Insights on the digitalisation of dental practices: A cross-sectional pilot study in Hesse

Aim: Even though today, many fields in dentistry allow digital processes, analogue procedures are still widely used. This cross-sectional pilot study aimed to survey insights on the digitalisation of dental practices using the example of Hesse. Materials and Methods: Between April and June 2022, 4840 active practicing dentists registered by the State Dental Association of Hesse were invited via e-mail to fill out an online questionnaire regarding their technical requirements in dental practice, dental treatment procedures, and attitude towards digitalisation in dentistry. Demographic questions were asked. Besides descriptive statistics, correlations were analyzed (P < 0.05). Result: Questionnaires of 937 dentists (279 female, 410 male, four inter/divers, 244 no answer; mean age of 51.4 ± 10.4 years) were examined representing a respond rate of 19.36%. In the area of practice administration and dental radiography, the majority of the dentists surveyed is already working digitally, which is predominantly assessed as a positive development. Already one third of the respondents state that they use an intraoral scanner for dental treatments, but the indication is mainly limited to smaller restorations. However, many dentists rate the use of social media accounts and telemedicine rather negative. Conclusion: Within the limitation of this pilot study, many processes especially in dental treatments are still analogue. However, 60% of the participants plan digitalisation of their dental practices within the next five years, which indicates a clear shift from analogue to digital dentistry.

Oral health in the elderly: results of the 6th German Oral Health Study (DMS • 6)

Objectives: Oral health plays a central role in overall well-being, including in the elderly. The demographic transition and its effects are resulting in a higher proportion of older people, both with and without care requirements. This paper provides an overview of the dental situation of the elderly from the 6th German Oral Health Study (DMS • 6). Method and materials: DMS • 6 is a population-representative oral epidemiologic study that surveys oral health in Germany. Data from 797 younger seniors aged 65 to 74 were collected by calibrated examiners. The methodology remains largely consistent with that of the previous studies. Results: Among the younger seniors (65- to 74-year-olds), edentulism has more than halved to 5.0% compared to the Fifth German Oral Health Study (DMS V) (12.4% in 2014). The mean number of missing teeth (8.6) decreased further, compared to DMS IV (14.1) and DMS V (11.1). At 18.8 teeth, the FST Index (number of filled or sound teeth) has shown improvement compared to the previous studies (DMS IV, 13.6; DMS V, 16.4). The root caries (59.1%) increased compared to DMS IV (28.0%). Caries experience (decayed, missing, filled teeth [DMFT]: 17.6), in contrast, hardly changed from DMS V (17.7). Half of 65- to 74-year-olds were diagnosed with moderate periodontitis (49.4%) and almost a third (30.4%) with severe periodontitis. In younger seniors with care requirements, therapeutic capability was greatly reduced for almost half (47.4%) and oral hygiene ability for one fifth (18.5%). Conclusion: The prevalence of tooth loss and edentulism among younger seniors in Germany continues to decline. Due to further morbidity compression, the challenges of dental treatment lie in the continuous treatment of younger seniors to prepare them for older stages of life.

Tooth loss and denture status: results of the 6th German Oral Health Study (DMS • 6)

Objectives: The German Oral Health Study (DMS) is a series of consecutive studies designed to assess the oral health status of adults, seniors, and children in Germany. DMS is a major program of the Institute of German Dentists (Institut der Deutschen Zahnärzte) with the aim to produce health statistics for Germany. Tooth loss, edentulism, and prosthetic care have considerable socioeconomic significance; it is the aim of this paper to report findings on these aspects. Method and materials: The survey combines interviews and clinical examinations. Previous DMS studies focused primarily on tooth loss, edentulism, and prosthetic care. In the DMS • 6 survey, the condition of removable dentures and need for adjustments were additionally recorded, as well as necessary repair measures that were grouped according to their complexity (chairside or laboratory). Results: The prevalence of edentulism decreased considerably compared to that in the Fifth German Oral Health Study (DMS V) in 2014. Among younger adults (35- to 44-year-olds), the prevalence of edentulism was negligible, with an average of 26.6 teeth present. The younger senior group (65- to 74-year-olds) had an average of 19.3 teeth; the prevalence of edentulism was 5%, which is a reduction of > 50% compared to 2014 (12.4%). Lower education status was an important prognostic factor for tooth loss. Owing to the low prevalence of edentulism in younger adults, removable dentures were not prevalent in this age group, whereas combined fixed–removable dentures were most frequently used in seniors. Regarding the type of denture, a shift towards fixed as well as implant-supported types was observed. Of the removable dentures, 50% to 60% were in a very good or good clinical condition. Problems were mainly identified with simple acrylic dentures. Nonetheless, participants’ satisfaction with removable dentures was extremely high, and the dentures were used almost continuously. Conclusion: The most important finding in this study is the continued significant decline in the prevalence of complete edentulism among seniors that suggests a further reduction in edentulism in the future with an estimate of around 4% in 2030. The shift observed in primary prosthetic care from removable to fixed prostheses as well as the increasing prevalence of implants placed are positive developments. The data revealed further compression of morbidity compared to DMS V. Complete edentulism declined, and fixed partial dentures, including implant-supported prostheses, were increasingly used. Lower education status was an important predictor for tooth loss. Schlagwörter: dental care, dental prostheses, dentists, DMS 6, edentulous mouth, epidemiology, tooth loss

Update on the Accuracy of Digital Implant Impressions: A Coordinate-Based Analysis

Purpose: To update data on the transfer accuracy of digital implant impressions using a coordinate-based analysis, the latest intraoral scanners (IOS) were investigated in an established clinical close model setup. Materials and Methods: An implant master model (IMM) of the maxilla with four implants in the posterior area (maxillary first premolars and first molars) and a reference cube were scanned 10 times each with four different IOS: i700 (i7; Medit), Primescan (PS; Dentsply Sirona), and Trios 4 (T4) and Trios 5 (T5; 3Shape). Datasets were compared to a reference dataset of IMM that was generated with x-ray computed tomography in advance. 3D deviations for the implant-abutment interface points (IAIPs) were calculated. Statistical analysis was performed by multifactorial ANOVA (P < .05). Results: Overall deviations for trueness (mean) ± precision (SD) of the IAIPs ranged from 88 ± 47 μm for PS, 112 ± 57 μm for i7, 121 ± 42 μm for T4, and 124 ± 43 μm for T5 with decreasing accuracy along the scan path. For trueness, a significant difference between the PS and the T4 was detected for one implant position. For precision, no significant differences were noticed. Conclusions: Although the latest IOS showed a significant improvement in transfer accuracy, the accumulating deviation along the scan path is not yet resolved. Considering the Trios system, the innovation seems to be limited because no improvement could be detected between T4 and T5.

Marginal Quality and Wear of Bulk-Fill Composites: Differences Between Dentitions

Purpose: The aim of this study was to evaluate the marginal quality and wear of bulk-fill composite resins (BFs) for Class-II restorations of primary and permanent molars in comparison to a conventionally layered composite resin (RC) and to compare the results of the two dentitions. Materials and Methods: Eighty (40 primary and 40 permanent) extracted molars received standardized Class-II cavity preparations and were restored with either one of two flowable BFs, one of two high viscous BFs, or a composite resin (RC). Thermomechanical loading (TML; 2,500 cycles +5°C/+55°C; 100,000 cycles, 50N, 1.67Hz) followed. A quantitative marginal analysis using SEM images and a profilometric quantification of two-body wear were carried out using replicas. ANOVA, Kruskal–Wallis, Mann–Whitney U, and Wilcoxon signed-rank tests were used for statistical analysis (P < 0.05). Results: For both dentitions, a significant reduction of perfect margins was observed after TML (P < 0.02). For the primary dentition, the flowable BFs showed significantly less perfect margins than all high viscous materials (P < 0.005). For the permanent dentition, RC showed significantly fewer gaps than the flowable BFs (P < 0.04). Regarding wear, within the dentitions, no significant differences could be computed between groups with regard to the maximum height loss (P < 0.05). Conclusion: All of the investigated bulk-fill composite resins showed satisfactory in-vitro results for both tested parameters in primary and permanent teeth, with a superiority of the high-viscosity materials in terms of marginal quality.

Survival of Double-Crown-Retained Implant-and-Tooth- Supported Removable Partial Dentures: A ≥ 5-Year Clinical Follow-up Study

Purpose: To assess the survival of double-crown-retained implant-and-tooth-supported removable partial dentures (DCR-ITSRPDs), evaluate abutment survival, and identify first aftercare measures. Materials and Methods: The influence of various factors on the survival of the DCR-ITSRPDs and the abutments were observed in this retrospective and clinical follow-up study using the Kaplan-Meier estimate. In addition, the first-required aftercare measure for each prosthesis was evaluated. Results: In total, 47 DCR-ITSRPDs were investigated (mean observation: 4.3 ± 3.8 years; max: 14.3 years), 3 of which (6.4%) had to be replaced. The survival probability for DCR-ITSRPDs was 100% at 5 years and 75% at 10 years. A total of 297 abutments (120 natural teeth and 177 dental implants) were observed, 22 of which (7.4%; 6 teeth and 16 implants) failed. The survival probability for teeth was 90.2% at the 5- and 10-year mark; for dental implants, it was 90.4% at 5 years and 76.3% at 10 years. Conclusions: DCR-ITSRPDs are a successful and durable treatment option for patients with substantially reduced residual dentitions. Both prostheses and abutments show good survival times after 5 and 10 years in function. The patient-associated factors tested showed no influence on the survival of DCR-ITSRPDs and abutments. Peri-implant infection was the decisive factor for abutment loss; therefore, regular dental prophylaxis and examinations are of major importance.

Zusammenhang zwischen chronischen Lebererkrankungen und Parodontitis

Diskussionsbeitrag des Masterkurses „Parodontologie und Implantattherapie“ der DG PARO und DIU

Parodontitis ist eine multifaktorielle Erkrankung, welche primär durch organisierte Mikroorganismen des oralen Biofilms verursacht wird und im Zusammenhang mit einer Vielzahl entzündlicher Erkrankungen steht. Der Zusammenhang zwischen Parodontitis und chronischen Lebererkrankungen rückt dabei immer mehr in den Fokus der Forschung. Tierstudien und klinische Studien fanden parodontopathogene Bakterien in der Leber, die über den Gastrointestinaltrakt oder direkt durch die Entzündungsreaktion im Parodont in den Blutkreislauf der Leber gelangt sein könnten. Erkrankungen wie die nichtalkoholische Fettleber, die nichtalkoholische Steatohepatitis, die Leberzirrhose und das hepatozelluläre Karzinom können sich dadurch manifestieren. Nach einer Parodontitistherapie kann es zu einer Remission hepatogener Entzündungsparameter kommen. Ein kausaler Zusammenhang ist bisher noch nicht evident. Im Rahmen des DIU-Masterstudiengangs für Parodontologie und Implantattherapie der DG PARO erfolgte zu diesem Thema eine Literaturrecherche mit dem Fokus auf die nichtalkoholische Fettleber. Die Ergebnisse werden in dem folgenden Diskussionsbeitrag dargestellt, wichtige Studien werden präsentiert sowie kritisch evaluiert und ein Ausblick aufgezeigt. Schlagwörter: Parodontitis, Lebererkrankung, nichtalkoholische Fettlebererkrankung, nichtalkoholische Steatohepatitis, Oral-Gut-Liver-Axis

Marginal Quality and Wear of Bulk-fill Materials for Class-II Restorations in Primary Molars

Purpose: The aim of this in-vitro study was to evaluate the marginal integrity and wear of eight bulk-fill materials in comparison to a compomer in Class-II cavities in primary molars after thermomechanical loading (TML). Materials and Methods: Prepared Class-II cavities in 72 extracted primary molars were filled with eight bulk-fill materials. A compomer served as the control group. After water storage (incubator, 28 days, 37°C), samples were subjected to TML (2500 thermal cycles 5°C/55°C; 100,000 load cycles, 50 N, 1.67 Hz). Before and after TML, replicas were made which were used for both SEM analysis of marginal integrity and 3-D wear analysis. Statistical analysis was performed using Kruskal-Wallis and Wilcoxon tests (p < 0.05). Results: A significant reduction in perfect margins was observed for all groups, while marginal gap formation increased (Wilcoxon test, p < 0.02) for all groups but the compomer. Significant interindividual differences were observed between the tested materials regarding marginal integrity (Kruskal-Wallis test, p < 0.05). Wear analysis revealed no significant differences between groups (Kruskal-Wallis test, p > 0.05). Conclusion: Some of the bulk-fill materials investigated here achieved better results than the compomer and should be further evaluated clinically.
