Aug. 2024,Seiten: 1-36, Sprache: EnglischZheng, Wentian / Pang, Yongzhi / Gong, Hui / Shi, Min / Song, Ning / Guo, Tao / Jiang, YingyingObjectives: Diode laser represent a practical clinical strategy for treating gingival hyperpigmentation. However, its effectiveness remains controversial. We conducted a meta-analysis evaluating the quantitative effects of diode laser therapy on gingival hyperpigmentation. Method and materials: Pubmed, Embase, Web Of Science, and Cochrane Library were systematically searched for the use of diode laser in gingival hyperpigmentation. The primary outcomes assessed were the Dummett-Gupta Oral Pigmentation Index (DOPI), Visual Analog Scale (VAS) pain scores, and the Wound Healing Index (WHI) for overall evaluation. I2 index was calculated to identify heterogeneity and sensitivity analyses sources of heterogeneity. Funnel plots and Egger's test were utilized to evaluate publication bias. Results: Thirteen randomized controlled trials (RCTs) involving a total of 233 participants were included in this study. The analysis demonstrated that diode laser had a significant effect on DOPI (standard mean difference [SMD] = -0.245, 95% CI = -0.415 to -0.040, P =.019) and VAS (SMD = -0.089, 95% CI = -1.332 to -0.285, P =.002), with no significant effect on WHI (SMD = -0.224, 95% CI = -1.100 to 0.653, P =.617). Despite the significant heterogeneity in VAS and WHI indicated by the I2 index statistic, the sensitivity analyses' results demonstrated the main findings' reliability. While no significant publication bias was detected for DOPI and WHI, the VAS results exhibited notable publication bias. Conclusion: The study demonstrated that diode laser prolongs gingival repigmentation time and reduces pain compared to other treatments. However, the efficacy in wound healing did not significantly promote.

Aug. 2024,Seiten: 1-24, Sprache: EnglischSonnenschein, Sarah K. / Reccius, Ingvi / Kilian, Samuel / Kim, Ti-SunObjective: To evaluate two methods for assessing the changes in periodontitis grading in patients undergoing supportive periodontal therapy (SPT) ten years (T10) after retrospective baseline (BL) grading. Materials and Methods: The periodontitis grade of 51 SPT-patients was assessed using indirect evidence as the primary criterion for periodontitis progression at BL and T10 (radiographic bone loss/age index, periodontitis phenotype). Grading at T10 was also performed using the direct evidence for periodontitis progression (clinical attachment loss over the previous five years). The use of indirect evidence for periodontal progression at BL and T10 was defined as method 1 (M1) to assess the changes in periodontitis grading. The use of indirect evidence at BL and direct evidence at T10 was defined as method 2 (M2). Changes in periodontitis grading using M1 and M2 were evaluated (Wilcoxon signed-rank test). Agreement between M1 and M2 was assessed (Cohen's kappa). Results: Indirect BL-grading revealed five grade B and 46 grade C patients. The indirect grading at T10 revealed 17 grade B and 34 grade C patients. The direct T10-grading classified all patients as grade C. M1 led to an overall improvement in periodontitis grading after ten years of SPT (p=0.00297), whereas M2 led to a deterioration (p=0.0369). The comparison between M1 and M2 showed that they lead to different results in terms of grading (Cohen's Kappa=0.116208). Conclusions: Periodontitis grading may change during SPT. Using indirect or direct evidence as the primary grading criterion during SPT may lead to different results.

Aug. 2024,Seiten: 1-23, Sprache: EnglischThies, Anke / Backhaus, Joy / Olmos, Manuel / Eitner, StephanObjectives: Prevalence of work-related musculoskeletal disorders (WRMSDs) among dentists and orthodontists is approximated to range between 64%-93%. Etiology of WRMSDs in the mentally and physical demanding occupation remains unclear, for which reason aim of the study was to clarify the interplay of physical, psychological, and mental factors on WRMSDs Material and Methods: Of 94 orthodontists and 187 dentists, (Mage=35 years) questioned using an online-survey, 84% reported persisting tension or pain in the back, neck, or shoulders. While 71% of females were employed (29% self-employed), solely 39% of male participants were employed. Cluster analysis was used to characterize dentists according to their movement profile and the moderating effect of stress on WRMSDs scrutinized. Results: Three movement profiles of dentists and orthodontists were significantly predictive of WRMDS. The minority could be characterized as healthy (n=45), whereas twice as many reported nearly twice as much pain (n=90). Stress proved to be a strong, significant moderator of WRMDs in relation to gender, employment status, and BMI. Conclusion and Outlook: Prevalence of WRMSDs found in this study is alarming. Given the feminization of dentistry the being a female, stressed and an employee (rather than self-employed) a significant predictor of WRMSDs represents a serious danger to the German health system.

Juli 2024,Seiten: 1-27, Sprache: EnglischLy-Mapes, Oriana / Jang, Hoonji / Al Jallad, Nisreen / Rashwan, Noha / Castillo, Daniel A. / Lu, Xingyi / Fiscella, Kevin / Xiao, JinObjectives: Although early-life dental care is crucial for preventing early childhood caries and has numerous benefits, the utilization rate of such care remains remarkably low worldwide, especially in families of low socioeconomic status. The aim of this study was to systematically review the scientific evidence relating to the effectiveness of interventions on improving early-life dental care utilization of very young children. Method and materials: We reviewed scientific evidence relating to these positive changes, with 7 randomized controlled trials after qualitative evaluation. Interventions assessed included prenatal oral health promotion, motivational interviewing, intraoral camera use alongside social work consultations to aid in decreasing barriers to care, monetary incentives for tooth brushing, fluoride varnish applications, and probiotic usage. Results: The intervention was significantly effective in reducing the incidence of dental caries among children, especially in caries risk. Caries reduction was significant when oral health information was provided at frequent intervals prenatally. Caries increment was also reduced when probiotics were introduced when administered daily. Interventions that attempted to increase parental involvement in oral health care by increasing motivation and decreasing barriers had inconclusive results within the study groups. Conclusions: Considering high rates ECC, early establishment and preservation of a dental home should be a focus in public health measures. Continuous monitoring and parental involvement are key components to maintaining healthy oral conditions. Future studies could explore and test various innovative strategies that utilize technological platforms to engage with parents and promote early-life dental care utilization among the underserved population.

H. / Gopinath, Vellore KannanObjectives: This randomized clinical trial compared the effectiveness of music and informative videos as distraction tools to reduce the anxiety of patients during root canal treatment and retreatment. Method and materials: A total of 90 patients were enrolled in the study. The patients were randomly allocated to three groups: Group 1 listened to music during the treatment (n=30), Group 2 watched an informative pre-operative video (n=30) and a control group underwent treatment without a distraction method (n=30). Prior to treatment, the Corah Dental Anxiety Scale (CDAS) and a visual analogue pain scale (VAS) were used to assess anxiety and pre-operative pain. Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) and oxygen saturation (OS) were recorded before the intervention (T1), after the local anesthetic (T2), following pulp extirpation or removal of root fillings (T3), and immediately following rubber dam removal (T4). One-Way ANOVA, followed by post-hoc Bonferroni tests for multiple comparisons, were used to compare mean values of SBP, DBP, HR, and OS among the groups. A P-value of 5% was considered as significant. Results: Listening to music reduced SBP, HR (P <.001) and DBP (P =.003) in patients undergoing root canal treatment and retreatment at T4 compared to the baseline (T1). Music (P <.001) and informative video (P =.003) groups had significantly lower post-operative VAS-pain scores. Conclusion: Listening to music during root canal treatment and retreatment reduced anxiety levels in patients compared to informative pre-operative videos and no distraction technique.

Juli 2024,Seiten: 1-31, Sprache: EnglischTagger-Green, Nirit / Refael, Asaf / Szmukler-Moncler, Serge / Nemcovsky, Carlos / Chaushu, Liat / Kolerman, RoniBackground: Periodontal disease is caused by subgingival bacteria that adversely affect the host immune system and create and maintain unmitigated inflammation in gingival and periodontal tissues. The condition is also linked to systemic conditions including cardiovascular disease, diabetes, and arthritis. Periodontitis elevates the bacterial load and spreads systemic inflammation through infection and inflammation. The main radiographic sign of periodontitis is marginal bone loss. Risk factors, including medications, smoking, age, and gender, are known to influence periodontal health. However, there is little information about the impact of systemic conditions, and medications on tooth wear. Aim: To assess the association between systemic conditions and medications and radiographic signs of tooth wear (TW) and marginal bone loss (MBL) . Materials and methods: This retrospective analysis was conducted on a group of 2223 consecutive patients who came for dental treatment in the clinics of a large HMO in Israel. Data available for the study included details of concomitant systemic diseases and medication and full-mouth radiographic surveys. Odds ratio and logistic regression analysis were used to detect associations between systemic conditions and medication, and MBL and TW . Results: The results indicated an elevated odds ratio for TW associated with age, gender, and smoking across all age groups. Among young patients, those using proton pump inhibitors and psychiatric medications had an elevated risk of TW. Age, smoking, and diabetes conditions were associated with an increased odds ratio for MBL in all age groups. Psychiatric medications and gender elevated the odds ratio for MBL only among older patients. Conclusion: Our results highlight the significant impact of age, gender, and smoking on tooth wear and extend these risks to alveolar bone loss when combined with diabetes and psychiatric conditions.

DOI: 10.3290/j.qi.b5586051, PubMed-ID: 3901667117. Juli 2024,Seiten: 1-23, Sprache: EnglischWong, Kristal / Nadella, Srighana / Mupparapu, Mel / Sethna, ChristineObjective: The aim of this study was to identify the relationship between preventative dental practices and cardiometabolic health in adolescents.
Methods: Analysis included children aged 13-17 years enrolled in the National Health and Nutrition Examination Survey (NHANES) from 2011-2018 who completed an Oral Health Examination and Questionnaire. Deferred dental care was defined as not having a dental visit in the past year. Financial barriers to seeking dental care (vs. no financial barriers) were assessed among those with deferred dental care in the past year. Primary cardiometabolic outcomes included obesity, elevated blood pressure and hypertensive blood pressure. Secondary outcomes included dyslipidemia, glucose intolerance, uric acid, glomerular hyperfiltration, and albuminuria. Regression models adjusted for age, sex, ethnicity, household income, food insecurity, health insurance status, household education, and body mass index z-score examined associations using complex survey design procedures.
Results: Of 2,861 adolescents, 17.6% (SE 0.9%) did not receive dental care in the past year and 20.2% (SE 1.9%) had a financial barrier to accessing dental care. In adjusted regression models, adolescents with deferred dental care had higher odds of dyslipidemia (OR= 1.51, 95% CI 1.07, 2.11 p = 0.020). Having a financial barrier was associated with a lower odd of dyslipidemia (OR=0.35, 95% CI 0.14, 0.89 p = 0.03). Financial barriers were associated with lower non-HDL (b=-7.95, 95% CI -14.87, -1.05 p=0.03) and higher HDL (b=3.06, 95% CI 0.37, 5.75 p=0.03) in adjusted models. Deferred dental care and financial barriers were not associated with any other cardiometabolic parameters.
Conclusion: In this nationally representative cohort of adolescents, there was an association between lack of preventative dental care and the cardiometabolic health marker of dyslipidemia. However, financial barriers to dental care were surprisingly associated with higher HDL levels and lower odds of dyslipidemia.

Juli 2024,Seiten: 1-21, Sprache: EnglischMao, Tianfu / Wang, WeilinObjective: This review aimed to examine differences in outcomes with the use of intra-articular hyaluronic acid (HA) vs corticosteroids (CS) after temporomandibular joint (TMJ) arthrocentesis.
Methods: Studies were searched on PubMed, Embase, Web of Science, and Google Scholar up to 15th January 2024. Randomized controlled trials (RCTs) comparing HA with CS after TMJ arthrocentesis were included. The outcomes were pain and maximal mouth opening (MMO).
Results: Ten articles corresponding to nine RCTs were included. There was no statistically significant difference in pain scores at 1 week (MD: -0.30 95% CI: -1.25, 0.65 I2=0%), 1 month (MD: -0.55 95% CI: -1.23, 0.13 I2=0%), and 6 months (MD: -0.57 95% CI: -2.10, 0.96 I2=58%) between the two groups. However, pain scores were found to be significantly lower in the HA group at 3 months (MD: -1.07 95% CI: -1.84, -0.31 I2=0%). No statistically significant difference was noted in MMO at 1 week (MD: 0.78 95% CI: -1.79, 3.35 I2=0%), 1 month (MD: 0.32 95% CI: -1.83, 2.46 I2=0%), and 3 months (MD: -0.41 95% CI: -3.90, 3.07 I2=0%) between the two groups. Descriptive analysis for studies not included in the meta-analysis also presented similar results.
Conclusions: Low-quality evidence suggests that both intra-articular HA and CS have similar efficacy in improving pain scores and MMO after TMJ arthrocentesis.

DOI: 10.3290/j.qi.b5566187, PubMed-ID: 3898543910. Juli 2024,Seiten: 1-22, Sprache: EnglischBrandt, Silvia / Winter, Anna / Lauer, Hans-Christoph / Romanos, Georgios E.Objectives: To evaluate clasp-retained removable partial dentures (C-RPDs) with a metal framework for survival, maintenance requirements, and biological implications.
Method and Materials: C-RPDs were retrospectively analyzed based on patient records. Treatment failure was defined as fracture of a framework component (metal base or connector) or loss of an abutment tooth. Other outcome variables included factors that might conceivably impact C-RPD survival (maxilla vs. mandible, Kennedy classes, opposing dentitions, treatment by students vs. certified dentists), mobility and caries of abutment teeth (in relation to clasp designs), and maintenance requirements (relining, clasp or resin fractures). Differences were evaluated by appropriate statistical tests at the P ≤ .05 level.
Results: A total of 612 patients (339 men, 273 women) 60.0 ± 11.5 years old at delivery were included, covering 842 C-RPDs and a mean observation period of 42.1 ± 33.2 months. Kaplan-Meier C-RPD survival was 76.2% after 5 years and 49.5% after 10 years. Biological complications (i.e. loss of abutment teeth) accounted for the vast majority (95.6%) of C-RPDs failures, and Kaplan-Meier C-RPD survival was significantly better in the mandible (P = .015). Some clasp designs contributed significantly to caries and removal of abutment teeth (both P < .05). No other significant differences were noted.
Conclusion: Tooth loss both emerges as the main cause of C-RPDs failure and might be amenable to careful selection of clasp designs. Overall, better C-RPD survival should be expected in the mandible. A non-contributory role of Kennedy classes and opposing dentitions is tentatively suggested based on numerically heterogeneous subgroups.

DOI: 10.3290/j.qi.b5566159, PubMed-ID: 3898543810. Juli 2024,Seiten: 1-23, Sprache: EnglischDegirmenci, Kubra / Yalin, MelikeObjectives: This study aimed to evaluate the effect of the clinical removal of fixed partial dentures (FPDs) on oral health-related quality of life (OHRQoL) and the anxiety values of individuals and to determine the clinical factors of high anxiety levels.
Method and Materials: In total, 300 participants were included in this study. Six different reasons for the clinical removal of FPDs (oral examination, denture renewal, endodontic treatment, tooth extraction, periodontal treatment, and composite filling restoration) were defined. The United Kingdom Oral Health-Related Quality-of-Life Measure (OHRQoL-UK), the Modified Dental Anxiety Scale (MDAS), and the Spielberger State-Trait Anxiety Inventory- State (STAI-S) and Trait (STAI-T) were answered. The reason groups were compared using one-way analyses of variance (ANOVA). Binary logistic regression analyses were performed to evaluate the risk factors for high anxiety.
Results: There was no significant difference in OHRQoL-UK scores (P=.279) among the reason groups, but there were significant differences in MDAS, STAI-S, and STAI-T scores (P=.004, P<.001, P=.018 respectively) among the reason groups. Endodontic treatment, tooth extraction, and gender were determined to be risk factors, considering the anxiety scales.
Conclusions: Females are 2.2 times more likely to have trait anxiety than men. Although the effect of the reason for the clinical removal of FPDs on OHRQoL was similar among the groups, it is concluded that endodontic treatment and tooth extraction reasons for the clinical removal of FPDs could be risk factors for high anxiety regardless of FPD usage time.

Method and materials: Fifty bovine incisors were selected, cleaned, and stored before being divided into five groups: a conventional toothpaste group (C) and three whitening toothpaste groups containing different abrasive agents: silica (S), hydrogen peroxide (PH), and activated charcoal (CA). Specimens underwent simulated brushing, staining with black tea solution, and subsequent analyses of color, surface roughness, and microhardness. Statistical analysis was performed using three-way ANOVA and Tukey post-hoc tests (P < .05).
Results: The results showed that the color analysis revealed similar whitening potential among all toothpastes. Otherwise, showed significant differences in surface roughness (P < .001) and microhardness (P < .001) after simulated brushing. While all toothpastes caused a decrease in microhardness, the charcoal-based toothpaste showed a significant increase in surface roughness compared to the initial condition.
Conclusion: All toothpastes demonstrated whitening capability. Surface roughness changed after brushing with activated charcoal-based whitening toothpaste, but final roughness was similar across all groups. Whitening toothpastes led to a decrease in enamel microhardness, with similar final performance across all toothpastes analyzed.

Oliver / Roehl, Jakob C. / Jakstat, Holger A. / Kielbassa, Andrej M.Objectives: To evaluate the survival rate of minimally invasive semipermanent occlusal polymethylmethacrylate (PMMA) onlays/veneers in previous temporomandibular disorder (TMD) patients with severe tooth wear and with a loss of vertical dimension after up to 7 years.
Method and materials: This case series was designed as a follow-up evaluation with consecutive patient recruitment. All patients bearing the indication for this kind of rehabilitation were treated by the same clinician using the same adhesive methodology. The study included 22 patients (3 males/19 females), with a mean [SD] age of 50.7 [11.6] years. Controls followed within the first 4 weeks (and subsequently as required). Failure criteria included damage by fracture, chipping, and retention loss. Survival rates were determined based on the Kaplan-Meier analysis.
Results: 328 semipermanent occlusal/incisal veneers were included (142 maxillary/186 mandibular teeth). Almost 80% of the restorations were in place and in function when starting the follow-up treatment after 180 days; failures predominantly occurred within the first 3 to 6 months but proved reparable. Depending on the patients’ priorities, scheduled replacements followed successively, and more than 65% did not show repair or any renewal needs for more than 360 days.
Conclusion: Within the limitations of this study the survival rates of occlusal veneers made of PMMA were sufficiently high to allow for consecutive treatment of the respective teeth by means of permanent restorations while preserving the restored vertical dimension. In patients with severe tooth wear and a TMD history, semipermanent restorative therapy with occlusal PMMA onlays/veneers would seem a noteworthy option.

DOI: 10.3290/j.qi.b5503749, PubMed-ID: 3891267124. Juni 2024,Seiten: 1-32, Sprache: EnglischManor, Yifat / Safadi, Hanan / Shpack, Nir / Blumer, Sigalit / Gal, GabrielObjective: The study aims to provide a comprehensive case analysis from a single center, with the objective of clarifying the optimal timing and recommending a preferred treatment strategy customized to the specific presentation of each type of supernumerary tooth (SNT) identified in our research.
Methods and Material: A retrospective study was conducted on patients who presented with SNT and were treated through an interdisciplinary at the clinic.
Results: 55 patients with 81 SNT of the permanent dentition were analyzed. They included 30 males and 25 females. The dentition status of the patients was as follows: 31 patients with mixed dentition, 0 patients with deciduous dentition, and 24 patients with permanent dentition. The diagnosis of SNT diagnosis was primarily made by general or pediatric dentists and/or orthodontists. Patients were then referred to maxillofacial surgeons for treatment decision. The timing of treatment was mainly determined by the oral surgeon, based on the recommendations of the other specialists involved. Cases involving mal-eruption or malalignment of permanent teeth required both surgical and orthodontic treatment. Patients over 9 years old were treated either under local anesthesia or sedation, while those under 9 years old were treated under deep sedation or general anesthesia A comprehensive investigation of cases involved the utilization of cone beam computerized tomography (CBCT) at the SNT site to facilitate treatment planning. There was a significant correlation between younger age and the preference for treatment under sedation or general anesthesia (p=0.01, t-test). Similarly, a strong association was found between younger age and the need for additional orthodontic treatment (p=0.016, t-test). Cases of surgical removal of SNT at a young age typically did not require orthodontic traction of the permanent tooth, in contrast to cases of late surgical intervention (patients over 11 years old), which often did necessitate such traction. There was a strong tendency for treating supernumerary teeth (SNT) in the maxilla. The proximity of SNTs to vital anatomical landmarks significantly influenced treatment decisions. Patients with SNTs near the mental foramen or the inferior dental canal in the premolar area were exclusively placed under follow-up care (p=0.002, Pearson’s chi-square test). However, in the maxilla, the proximity of SNTs to vital structures such as the floor of the nose and the incisive nerve did not affect the treatment approach, and those supernumerary teeth were mostly removed.
Conclusions: A team approach for managing supernumerary teeth (SNT) is recommended. The timing of treatment should carefully consider the advantages and disadvantages of early versus late intervention. Early surgical treatment in cases where eruption is disturbed might result in spontaneous eruption, eliminating the need for orthodontic traction of the permanent teeth.

DOI: 10.3290/j.qi.b5465309, PubMed-ID: 3887421014. Juni 2024,Seiten: 1-32, Sprache: EnglischKrikeli, Eleni / Lambrianidis, Theodoros / Molyvdas, Ioannis / Mikrogeorgis, GeorgiosObjectives: The purpose of the present study was the radiographic evaluation of endodontically treated teeth presenting periapical radiolucency and unintentional overfilling with gutta-percha or sealer on treatment outcome and persistence of the extruded materials.
Method and Materials: After assessment using periapical index (PAI), 202 roots filled with gutta-percha and zinc oxide eugenol sealer (Roth 811, Roth International), exhibiting unintentional overfilling and periapical radiolucency were selected. All cases had at least 1 year follow-up. Type of extruded material, periapical status, and removal/persistence of the extruded material were evaluated by two independent observers. Data were statistically analyzed using logistic and linear regression analysis.
Results: Tooth location (P <.001), follow-up period (P <.001), and type of extruded material (P =.004) significantly influenced treatment outcomes. Specifically, posterior roots exhibited better outcomes compared to anterior, and cases with overfilling of sealer showed superior healing potential compared to those with gutta-percha overfilling. Additionally, longer recall periods were associated with improved treatment success. It is also seen that the type of extruded material (P <.001) and follow-up period (P <.001) have significantly affected the presence of extruded material in the follow-up radiograph. The persistence of extruded material was greater when gutta-percha was extruded as well as extruded materials were less detected when the follow-up period was longer.
Conclusion: Teeth with periapical radiolucency and unintentional overfilling require longer follow-up intervals for effective monitoring of healing. Treatment outcome was associated with the type of extruded materials used in the present study. The persistence of those materials in the periapex did not affect healing.

DOI: 10.3290/j.qi.b5437505, PubMed-ID: 388471397. Juni 2024,Seiten: 1-17, Sprache: EnglischVerma, Richa / Tewari, Shikha / Anand, DeeptiObjective: Varying levels of sex hormones across the menstrual cycle in young systemically healthy females may alter tissue responses to plaque, resulting in increased gingival inflammation. Also, higher severity and prevalence of gingivitis has been demonstrated in adult females than males, attributed to hormonal changes. Further, literature reported that Gingivitis raises the levels of systemic inflammatory markers such as C Reactive Protein. This interventional trial aimed to evaluate the effect of supragingival scaling on serum highsensitivity C-reactive protein (hsCRP) levels along with periodontal parameters in systemically healthy women of reproductive age group with natural gingivitis.
Material and Methods: 57 women of reproductive age were enrolled into two groups. Test Group (n=30) comprised of systemically healthy women with gingivitis who received supragingival scaling. Control Group (n=27) included systemically and periodontally healthy females. Periodontal parameters [gingival index (GI), plaque index (PI), pocket probing depth (PPD), bleeding on probing (BOP)], and serum hsCRP levels were recorded at baseline for both the groups. Follow up of Test Group participants was done at 3 and 6 months.
Results: Serum hsCRP and periodontal parameters were significantly higher in Test Group than control group at baseline which decreased significantly after treatment in Test Group at 6 months follow up (p≤0.05). GI, BOP and hsCRP in Test Group at 6 months were reduced up to the baseline levels of systemically and periodontally healthy females.
Conclusion: Treatment of gingival inflammation can help in lowering the systemic and local inflammation up to the levels of systemically and periodontally healthy females.

Materials and Methods: This retrospective study included 94 patients who underwent implant placement using freehand (FH) or tooth-supported computerized surgical guide (TSSG) by the same operator between 2015 and 2020. Early implant failures occurring within one-year post-rehabilitation were assessed.
Results: In the study, two types of implants were placed using two different techniques: TSSG and FH. The TSSG group consisted of 84 S implants and 100 LP implants, while the FH group included 90 S implants and 94 LP implants. The results showed that more implants survived when placed FH compared to TSSG (181 (98.4%) vs 172 (93.5%) respectively, p < 0.05). The only significant factor affecting the success rate was the type of implant, with LP implants having a higher survival rate in the TSSG group (p < 0.05).
Conclusion: Surgeons should consider the impact of implant type on survival rates when utilizing the TSSG system.

Mai 2024,Seiten: 1-33, Sprache: EnglischZhang, Qinglai / Zhang, Yue / Lin, Lili / Meng, Fei / Jia, MengObjective: To determine the oral health status of patients on maintenance hemodialysis (MHD) and to identify the factors influencing their oral health.
Methods: This observational study included 1,186 patients with chronic kidney disease who received MHD across 33 hospitals in China. The patients were recruited for a questionnaire survey between April and August 2023 at Beijing Chaoyang Hospital using stratified sampling. Data collection tools included the General Information Questionnaire for Maintenance Hemodialysis Patients, the Oral Health Assessment Tool, the Pittsburgh Sleep Quality Index, and the Hospital Anxiety and Depression Scale. Spearman’s rank correlation coefficients were used to assess the relationships between the oral health of patients on MHD and continuous variables such as sleep quality and emotional status. Multiple linear regression analysis was employed to explore the relationship between oral health and various variables.
Results: The oral health scores of the patients ranged from 8 to 22, with a mean score of 12.54 ± 2.63. The final model of the multiple linear regression analysis indicated a goodness of fit of 22.19%. Independent factors affecting the oral health of patients included smoking, the proportion of medical expenses, water consumption, sleep quality, and anxiety scores (all P < 0.05). High levels of smoking, substantial medical expenses, poor sleep quality, and elevated anxiety scores were risk factors for poor oral health (all P < 0.05). Adequate daily water intake served as a protective factor for oral health (P < 0.05).
Conclusion: This study proposes targeted interventions to enhance the management and improvement of oral health in patients on hemodialysis, aiming to provide highly personalised and effective oral health care. These interventions are expected to improve oral health outcomes in future clinical practice.

Mai 2024,Seiten: 1-21, Sprache: EnglischKablan, Fares / Fahoum, Abdallah / Moreinos, Daniel / Srouji, Samer / Slutzky-Goldberg, IrisObjective: An altered sensation during endodontic treatment can occur due to the extrusion of endodontic materials. This study aims to discuss intentional replantation to address paresthesia resulting from an endodontic file penetrating the inferior alveolar nerve canal (IANC) and provide a protocol for managing nerve injuries in such incidents.
Case presentation: A 12-year-old girl developed paresthesia when an endodontic file separated and was inadvertently pushed through the apical foramen into IANC during root canal treatment of the mandibular left first molar. A CBCT scan revealed the file penetrating the canal towards the inferior border of the mandible. After considering the treatment options, intentional replantation was deemed suitable. The tooth was a-traumatically extracted and preserved in sterile saline. The surgeon then carefully cleaned and irrigated the socket. The radiographic assessment confirmed successful file removal from the socket. The Root ends were resected, and retrograde preparation and obturation were conducted using ultrasonic tips and MTA. The tooth was then replanted into the socket. Successful replantation was confirmed by tooth stability and an audible click. The patient was prescribed antibiotics and steroids. Subsequently, after completing the endodontic treatment. a stainless-steel crown was cemented. The successful intentional replantation procedure resulted in rapid improvement in the patient's condition. The normal sensation had been restored, indicating nerve recovery. At the 15-month follow-up, Periapical bone healing and the eruption of the adjacent second molar were observed, affirming the treatment protocol's overall success.
Conclusion: Prompt intervention and immediate intentional replantation facilitated direct inspection of the separated file within the socket. Collaboration between an oral maxillofacial surgeon and an endodontist ensures expedited and targeted treatment, leading to favorable outcomes.

DOI: 10.3290/j.qi.b5223635, PubMed-ID: 3863462718. Apr. 2024,Seiten: 1-16, Sprache: EnglischAhmed, Eilaf E. A. / Vielhauer, Annina / Splieth, Christian H. / Schmoeckel, Julian / Mourad, Mhd SaidBackground: Pre-eruptive intra-coronal radiolucency (PEIR) is a rare dental anomaly often incidentally detected during routine radiographic examinations. This condition manifests as a radiolucent lesion beneath the enamel-dentinal junction of unerupted teeth, particularly in lower molars, posing diagnostic and management challenges due to its asymptomatic nature. The treatment of PEIR depends on the extent of the lesion and the degree of pulp involvement.
Case series: This case series reports on four patients with progressive pre-eruptive intra-coronal radiolucency. In case 1 and 2, lesions were incidentally discovered in an OPG during orthodontic planning (lower permanent 2nd molars), and additional surgical exposure to access the lesion was required as teeth were only partially erupted. Interestingly in case 3, the PEIR was not visible in earlier x-rays though the crown of the tooth was already mineralized (lower permanent 2nd molar). For case 4, the tooth presented with symptoms of reversible pulpitis (lower permanent 1st molar). All lesions were treated with indirect pulp capping using biocompatible material. The patients were followed-up for a period of up to 8 years to evaluate treatment success. Indirect pulp capping and restorations were found to be successful in all four cases in the last follow-up: 1 year (case 2), 1.4 years (case 1), 1.5 years (case 4), and 8 years (case 3).
Conclusion: This case series demonstrates the effectiveness of early intervention via surgical exposure and indirect pulp capping and restoration for managing severe cases of PEIR. However, further research with larger samples and long follow-up is necessary.

Apr. 2024,Seiten: 1-21, Sprache: EnglischSayed Taha, Aisha M. / Almahdi, Wael H. / Alhamad, Nada A.Objectives: The frenum is a mucous membrane fold that attaches the lip and the cheek to the alveolar mucosa, the gingiva, and the underlying periosteum. Frenectomy is the surgical removal of the whole frenum, including the area connected to the bones. This study's purpose was to compare the healing period and postsurgical pain experienced by patients operated with diode and erbium:yttrium-aluminium-garnet (Er:YAG) lasers.
Methods: Twenty referred patients need to excision of the abnormal upper labial frenum were included in this study. Patients were randomly assigned into two groups; Diode group (810 nm, 2W, continuous emission, initiated tip) and Er:YAG group (2940 nm, 2W, 200 mJ, 10 Hz). Both lasers were applied in contact mode. Post-operative pain was assessed with Numerical Rating Scale (NRS) at post-operative 3rd hour and every day during the first week. Epithelialization process of the wound surface was evaluated by hydrogen peroxide solution applied to the wound on days 7, 14, 30, 60 and 90 following operations.
Results: The result shows mean values in Pain index after 3 hours (Diode Group 2.1±2.0, Er:YAG Group 2.6±1.4), 1st day (Diode Group 1.1±1.1, Er:YAG Group 1.9±1.4), and 2nd day (Diode Group 0, Er:YAG Group 0.9±1.1) and shows no significant difference after (3-7 days); p =1.00). In Healing index the results shows a significant difference between the Diode Group and the Er:YAG Group (after 7 days; p = 0.029 and 14 days; p = 0.001) and show no significant difference after (30-60-90 days; p = 1.00).
Conclusions: The Er:YAG laser has better clinical results in healing wounds, whereas the diode laser is better in decreasing pain after frenectomy during follow-up periods.

DOI: 10.3290/j.qi.b4925761, PubMed-ID: 382995991. Feb. 2024,Seiten: 1-19, Sprache: EnglischSubramanian, Gayathri / Yeung, Vincent / Baredes, Soly / Kim, Sung / Bergsbaken, Tessa / Quek, Samuel Y. P.Radiation treatment plays a mainstream role in the management of head and neck cancers (HNSCC). Adverse effects from radiation therapy include osteoradionecrosis of the jaw, and rarely, pathological fracture. Immune checkpoint inhibitors (ICI) such as pembrolizumab are of growing relevance to the management of metastatic and recurrent HNSCC. Adverse impact on bone secondary to medications such as pembrolizumab and nivolumab have been sporadically documented in the literature. The objective of this manuscript is to raise awareness of possible increase in risk for adverse jaw outcomes in patients with HNSCC exposed to both radiation treatment to the jaws and ICI therapy.
This manuscript documents adverse jaw outcomes including osteonecrosis and pathological fracture of the mandible in two patients receiving pembrolizumab for management of HNSCC and had received prior radiation treatment.
A potential link between immunotherapy and adverse jaw outcomes is consistent with our growing understanding of osteoimmunology, investigating the closely interrelated processes in bone remodeling and immune system function, in health and disease. It is important to ascertain if pembrolizumab poses an incremental risk for such outcomes, beyond the risk from prior radiation, for patients managed with radiation treatment and ICI therapy for HNSCC.
The general dentist may encounter such patients either in the context of facilitating dental clearance prior to initiation of chemotherapy, or rarely, with poorly explained jaw symptoms and must be alert to the possibility of occurrence of such adverse jaw events to facilitate timely diagnosis and optimal patient management.

Jan. 2024,Seiten: 1-25, Sprache: EnglischHamadeh, Wiam / Alhabashneh, Rola / Abdelhafez, Reem / Khader, YousefObjective: Currently, there is no established treatment protocol to treat Interdental papillary loss. This research aimed to evaluate the outcomes of interdental papillary reconstruction using minimally invasive surgery, with injectable hyaluronic acid (HA) gel.
Materials and Methods: Seventeen patients were included, each with five sites of class 1 papillary recession; (forty sites in the upper jaw and forty-five sites in the lower jaw). Subperiosteal tunneling was performed through a horizontal incision made apical to the base of the papilla without penetrating it. The free gingival sulcus was sealed by 000 retraction cord. After that a total of 0.2-0.6 mL HA was injected gradually. The incision was sutured with polyglycolic sutures. Treated sites underwent clinical and digital evaluation at three follow up time points (1 month, 3 months and 6 months).
Results: The interdental papillary defect height in the upper jaw sites significantly reduced by 60%, 66%, and 42% at 1 month, 3 and 6 months, respectively. Also, in lower jaw sites, the reduction was of about 54%, 55%, and 40% at the same follow up time points. Regarding interdental papillary defect surface area in the upper jaw the reduction was about 65%, 71%, and 45% at 1 month, 3 and 6 months. In the lower jaw, a reduction of about 60%, 64%, and 48% was noticed at the same time points. Regarding patients’ pain level score, during the day of surgery, sixteen patients reported pain, the average pain score out of 10 was 3.94, and eleven patients (64.7%) needed to take analgesics. The pain generally subsided in the following days. Also, at the day of the treatment twelve out of the seventeen patients (70.6%) reported mild difficulty in speaking and eating. No complication, hypersensitivity or allergy was noted in any patient.
Conclusion: Subperiosteal tunneling with HA injection demonstrates clinical improvements in papilla height and papillary recession surface area reduction after 3 months of follow-up with reduction in improvement after 6 months.

DOI: 10.3290/j.qi.b4790573, PubMed-ID: 3812671721. Dez. 2023,Seiten: 1-21, Sprache: EnglischTobias, Guy / Khaimov, Alexander / Zini, Avi / Sgan-Cohen, Harod D / Mann, Jonathan / Chotiner Bar-Yehuda, Yael / Aflalo, Efrat / Vered, YuvalObjectives: To assess the effect of Community Water Fluoridation (CWF) in the prevalence of dental caries and dental fluorosis in 12-year-old children living in Israel. Considering that CWF is important in the prevention of dental caries. Between 2002 and 2014, the water in communities of at least 5000 individuals was fluoridated. In 2014 CWF in Israel stopped.
Methods: Data on 12-year-old children from all areas in Israel from the national crosssectional epidemiological survey conducted in 2011-2012 were stratified by city water fluoridation and by city and school socio-economic status (SES). Two dependent variables were defined: (1) DMFT index -caries experience in the permanent dentition; (2) dental fluorosis in central incisors using the Thylstrup-Fejerskov (TF) classification of fluorosis.
Results: Data from 2181, 12-year-olds was analyzed. the average DMFT was 1.17+1.72 and 49% were caries free. Based on DMFT, the caries experience was significantly higher in nonfluoridated cities (1.38 vs. 0.98 in fluoridated cities) and there were more caries free children 56.4% in fluoridated cities vs. 40.6% in non-fluoridated. DMFT was higher in cities with lower SES than high SES (1.29 vs. 1.05 respectively, p<0.001) and there were less caries free children in low SES (44.5% vs. 53% in high SES cities, p<0.0001). Almost all the 10.3% of children with signs of fluorosis (scoring at least 1 in TF index), had questionable to mild fluorosis (9.3%).
Conclusions: CWF is a cheap, simple method of dental health protection that reaches all socio-economic levels and cessation of water fluoridation reduced the health of Israel's children.
Clinical Significance: Water fluoridation provides substantial caries prevention, by reaching a substantial number of people. The relevance of this work is for policymakers to consider CWF as clinically proven method for reducing health inequalities.
