Poster AwardPoster 2528, Sprache: EnglischGoudar, Archana Rangangouda / Puranik, R S / Puranik, Surekha R / Ramesh, Saahil / Amaran, E G Yog NaagThe Importance of Histopathological AnalysisOral soft tissue growths and swellings encompass focal reactive overgrowth (FROG), benign and malignant tumours. The diagnosis of these lesions is usually based on characteristic clinical and histopathological features. On rare occasions the clinical appearance of these is deceptive, exhibiting a benign appearance, whereby histopathology of the lesion will resolve the problem. This poster presents a rare case of high grade mesenchymal chondrosarcoma (MS) of mandibular gingiva in a 34 year-old male that was clinically misdiagnosed as pyogenic granuloma (FROG). MS is rare and represents approximately 1% of all chondrosarcomas with a predilection to affect the maxillofacial skeleton area. MS usually presents as a lobulated firm mass with a tendency to erode and expand bony confines. The current case radiologically showed ill-defined and ragged borders originating from the medullary portion. Histologically the tumour exhibited a classic biphasic pattern. The diagnosis was confirmed with IHC markers. This case illustrates the importance of a thorough clinical, radiological and histopathological evaluation to avoid mismanagement.

Poster AwardPoster 2551, Sprache: EnglischMahajan, Arjun / Jaiswara, Chandresh / Singh, Akhilesh Kumar / Nagarajan, Nachammai / Bansal, VyomikaAim: To establish a protocol for effective rehabilitation after maxillofacial injury, with loss of soft tissue, alveolar and basal bone. Background: Gunshot injuries to the head, neck and face account for 33.57% of overall gunshot injuries from North India, with interpersonal conflicts being the most common reason of all. Cavitation produced by short ranged projectiles cause extensive hard and soft tissue damage with degloving injuries. The complexity in facial skeletal anatomy poses multiple medical and surgical challenges to an operating surgeon, demanding elaborate soft and hard tissue reconstruction. The following case illustrates management of maxillofacial trauma caused by a point blank pistol projectile resulting in a degloving injury to the upper lip, premaxillary and mandibular anterior region. Case Description: Management of such critical cases commences with basic life support and ends with prosthetic rehabilitation. Hard tissue reconstruction was performed with a cortico-cancellous iliac crest bone graft and soft tissue restoration with microvascular radial artery forearm flap. After complete healing, mandibular cortical and maxillary zygomatic implants were placed. After successful loading with an interim prosthesis, a final prosthesis was planned. Conclusion: A multidisciplinary approach with an oral and maxillofacial surgeon, ENT surgeon, prosthodontist is indispensable to avoid therapeutic and restorative mishaps.

Poster 2614, Sprache: EnglischChatterjee, Puja / Devi, Anju / Narwal, Anjali / Kamboj, MalaIntroduction: Oral potentially malignant disorders (OPMDs) are a group of conditions that have the potential to transform into cancer if left untreated. Approximately 16–62% of OPMDs undergo a malignant transformation and eventually develop into oral squamous cell carcinoma (OSCC). The five-year survival rates of OSCC patients decrease from 80 to 40% if diagnosed at an advanced stage. Early detection of OPMD allows for prompt intervention and treatment. Although biopsy is the gold standard, patients still prefer a non-invasive approach for diagnosing his/her disease. Aim: This poster aims to present a review on the current advances in non-invasive tools for early diagnosis of oral potentially malignant disorders. Method: A comprehensive search of online databases including Pubmed, Medline and Scopus were conducted to identify studies from (January 2010 to Dec 2022) using search keywords ‘Oral screening devices’, ‘autofluorescence’, ‘chemiluminescence’, ‘oral malignant lesions’, ‘imaging techniques’, ‘non-invasive tools’, ‘oral dysplasia’, etc. A total of 24 studies were reviewed and evaluated based on their sensitivity and specificity. Result: Results of the studies were tabulated and representation of their sensitivity and specificity was done to evaluate the diagnostic accuracy. Conclusion: None of the analysed techniques based on assessing oral images can replace biopsy. Further studies are needed to explore the role of these emerging techniques to identify an early non-invasive screening method for early detection of OPMDs.

Poster 2615, Sprache: EnglischBarve, Madhura / Bhoosreddy, Ajay / Bhadage, ChetanIntroduction: Pain, swelling, pus discharge and ulceration of gingival tissue are the most common complaints that an oral physician encounter. Most of the time, these symptoms indicate gingival or periodontal pathology. Although this scenario is very common, such cases should be investigated thoroughly. We are presenting a similar case which presented to us with pain, swelling, pus discharge, and ulceration of gingival tissue. An episode of high-grade fever, malaise, nausea, and dysphagia led us to investigate the case further, thus identifying a severe disease. Case presentation: We present a case of acute necrotising ulcerative gingivitis (ANUG) in a 51-year-old woman with a history of diabetes and hypertension. The patient presented with a one-week history of fever and white, necrotic patches on the surface of the gingiva. Oral examination revealed halitosis, ulcerated, and painful and swollen gingiva, especially the anterior part. The differential diagnoses considered were gingival ulcers of viral origin and desquamative gingivitis. CBCT revealed mild to moderate bone loss. Lab investigation revealed underlying leukopenia, which later improved, and poorly controlled diabetic status. The case was managed by conservative oral treatment and management of the underlying systemic condition. Conclusion: This case highlights the importance of a thorough case history and appropriate investigations in diagnosing ANUG. In addition, a successful outcome of acute necrotising gingivitis depends on a multidisciplinary approach involving an oral medicine specialist, periodontist and general physician.

Poster 2616, Sprache: EnglischDokoupilová, Eliška / Vašáková, Jana / Borovec, Jiří / Koťová, MagdalenaBackground: This retrospective study describes the prevalence of dental caries and tooth number anomaly in primary and permanent dentition in children with a cleft lip and palate (CLP). Methods: In 47 children with CLP (24 boys, 23 girls; age 4-14 years) panoramic x-rays were investigated, 28 with primary and 23 with permanent dentition. Caries index dmft/DMFT was applied. Gender, type of the cleft (LAHSAL classification), and number of teeth in both dentitions were recorded. The statistics were performed using the chi-squared test, significance level p=0.05. Result: There was tooth agenesis in 34 % (n=16) children. The most commonly missing tooth was maxillary lateral incisor. The prevalence of supernumerary teeth was 45 % (n=21), praecaninus being the most common (n=20). There was a relationship in supernumerary teeth prevalence between cleft of primary and secondary palate (p=0.01). The prevalence of caries in children with primary dentition was 79 % (n = 22), in permanent dentition 56.5 % (n=13). No association between caries prevalence and gender was found. The average dmft was 4.64 (boys 4.0; girls 5.5); the average DMFT was 1.61 (boys 0.9; girls 2.31). There was no significant difference in DMFT in children with cleft of the primary and secondary palate. Conclusion: The prevalence of caries in children with CLP was higher in primary dentition and lower in permanent dentition than previously reported in a Czech population. There was no significant association between caries prevalence and gender. There were significantly more supernumerary teeth in children with cleft of the primary palate.

Poster 2620, Sprache: Englisch, DeutschWurche, Caroline / Wirth, Julia / Igelbrink, Sebastian / Renz, Cornelius / Kleinheinz, JohannesEinleitung: Die tumorassoziierte Mangelernährung stellt ein oftmals unbeachtetes Problem dar, obwohl bereits fast 60% aller onkologischen Patienten vor der Diagnosestellung mangelernährt sind und über 25% an den Folgen versterben. Material und Methoden: Im Rahmen dieser prospektiven Beobachtungsstudie wurde der Ernährungszustand von Patienten mit oralem Plattenepithelkarzinom (PEC) prä-, peri- und postoperativ mittels Body- Mass- Index (BMI), Subjective Global Assessment (SGA) und Bioelektrische Impedanzanalyse (BIA) über vier Monate erhoben. Dysgnathiepatienten dienten aufgrund der vergleichbaren nasogastralen Sondenernährung als Kontrollgruppe. Ergebnisse: Patienten mit oralem PEC zeigten prätherapeutisch einen schlechteren Ernährungszustand als die Kontrollgruppe und erfüllten in SGA und BIA die Kriterien der Mangelernährung. Peri- und posttherapeutisch verschlechtere sich der Ernährungszustand in beiden Gruppen. In der Gruppe der Patienten mit oralem PEC verbesserte sich der Ernährungszustand ab der zweiten postoperativen Woche, dennoch war der Zustand zum Ende des Beobachtungszeitraums, weiterhin überwiegend im pathologischen Bereich gemäß BIA und SGA. In der Kontrollgruppe wiederum glich sich der Ernährungszustand in dem Beobachtungszeitraum dem Ausgangszustand wieder an. Schlussfolgerung: Mangelernährung ist basierend auf diesen Daten auch im Kollektiv der onkologischen Patienten mit oralem PEC weit verbreitet. Um den Ernährungszustand von oralem PEC-Patienten generell zu verbessern und somit auch die Prognose des Patienten wird empfohlen schon vor Therapiebeginn den Ernährungszustand mittels zu etablierendem Standardverfahren wie SGA oder BIA zu erfassen. Der BMI alleine ist hierfür nicht geeignet. Als integraler Therapiebestandteil sollte gezielt eine professionelle Ernährungstherapie eingeleitet werden, um die Prognose der Patienten zu verbessern.

Poster 2621, Sprache: EnglischAnand, Deepti / Tewari, Shikha / Kumar, Rajinder / Tanwar, NishiIntroduction: Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder causing hyperandrogenism and menstrual dysfunction. Periodontitis and PCOS are associated with systemic inflammation and insulin resistance and may influence each other. Hence, these two disorders may be linked through common pathophysiologic pathway. Therefore, reduction of insulin resistance offers the possibility of improving effects of metabolic derangements and inflammation. For this purpose many insulin-sensitising agents like metformin and myoinositol have been tried. Metformin decreases serum CRP levels where as myoinositol helps in reduction of inflammation by increasing plasmalogen synthesis. The aim was to assess inflammatory periodontal status in PCOS patients undergoing different medical treatments. Materials and Method: Patients (n=75) were recruited and divided into three groups: Control Group: Newly diagnosed PCOS Women, Group A: Patients taking metformin for 6 months, and Group B: Patients taking myoinositol for 6 months. The clinical examination included a full-mouth periodontal assessment: BOP (bleeding on probing), PD (probing depth), CAL (clinical attachment level), PI (plaque index) and GI (gingival index). Results: The comparison between the control group and test groups showed significant differences with respect to GI and BOP whereas non-significant differences were seen with respect to AGE, PI and PD and CAL. Non-significant differences were seen in periodontal parameters between group A and group B. Conclusion: Newly diagnosed PCOS females have higher measures of GI and BOP as compared to PCOS women on medical treatment, whereas no significant difference is seen in periodontal parameters between women taking different medical treatment. Thus despite having different mechanisms of action, both drugs may reduce the systemic inflammation and hence are helpful in reducing the local inflammation.

Poster 2627, Sprache: EnglischVašáková, Jana / Borovec, Jiří / Dokoupilova, Eliska / Duskova, JanaBackground: The aim of study was to evaluate parents’ and children's perception of two ways of conscious sedation in outpatient practice (inhalation nitrous oxide-oxygen factory prepared mixture N, and peroral intake midazolam mixture - M), and change in children's approach to food and oral hygiene afterwards. Methods: Parental informed consent was obtained for every patient. Inclusion criteria were ASA I, II, no medical contraindications for N/M, and fasting prior to sedation followed EAPD guidelines. 129 children (66 M ♀27♂39, mean age 5.07; 63 N ♀23♂40, mean age 6.63) participated in the study. Parents were asked to complete a short questionnaire immediately after sedation and were questioned about the change in the children's approach to food and oral hygiene at the next check-up. The Wilcoxon sign-ranked test was used to compare study groups at 5 % statistical significance level. Results: All parents would choose the same type of sedation next time p<0.001. Parental reasons for children's sedation were not dependent on sedation type, p = 0.17. Parents of M-treated children had more information about the sedation prior to it, p<0.001. There was a change in the children's approach to oral hygiene (p=0.018) and to sweet food (p=0.048) after N. Conclusions: No differences in parental perception between the two sedation methods were found. They would choose the sedation method they already experienced for the child at the next visit. Results revealed significant changes in the children's approach to food and oral hygiene after nitrous oxide sedation.

Poster 2629, Sprache: EnglischSrividya, A.Objective: The advent of AI in the field of dentistry and in forensic odontology is gaining momentum in the recent times. The current systematic review aims to determine the use of AI in dental age estimation. Methods: Using PRISMA guidelines, original articles from “PubMed”, “Scopus” and “Google Scholar” were searched using terms, viz “dental age estimation”; “artificial intelligence”; “neural networks”; and “convolution networks” from the period of 2017 to present. Inclusion criteria included English language original research with completely free access. Non-English, in vitro studies, and abstract only articles were excluded from the study. Results: Total 11 articles were included in the study. The studies were retrospective in nature. The studies showed that AI-based applications estimate the dental age more precisely and in a large population. The majority of the studies used machine learning, deep convolutional networks, and deep learning types of AI in their study. Conclusion: The use of AI in age estimation is an excellent tool for dental age estimation of large populations with precision. Further, large-scale studies using other imaging modalities are recommended.

Poster 2631, Sprache: EnglischBudakoti, Nancy / Khan, Saif / Gupta, N.D. / Rafat, Dalia / Ashraf, Hamid / Khan, Asad U.Introduction: Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance with onset during pregnancy and is associated with increased feto-maternal morbidity. Chronic inflammation has been implicated in the pathogenesis of GDM. Saliva being a biofluid can serve as a non-invasive and economical alternative to serum for diagnosing various local and systemic diseases. Objectives: To assess the relationship between salivary inflammatory biomarkers and GDM. Methodology: A PICOS framework was developed and keywords used to electronically search the relevant literature in PubMed. Four relevant and authentic articles were included which are written in English and published from 2011 to 2023. Result: Obesity and GDM in pregnant patients have been found to be associated with raised salivary inflammatory biomarker. A direct relationship was observed between GDM and salivary inflammatory biomarkers. Conclusion: GDM have a recognized association with systemic inflammation, and they are also at risk for adverse pregnancy outcomes. Saliva provides an easy, non-invasive, cost effective alternative to frequent serum inflammatory markers estimation. This review shows the potential of salivary inflammatory biomarkers as an adjunctive to serum biomarker and a potential scope of further research on larger more homogeneous populations, preferably following a longitudinal design to form statistically sound recommendations.

Poster 2633, Sprache: Englisch, DeutschWillich, Leon / Oelerich, Ole / Hanisch, MarcelFragestellung: Ziel dieser Studie war es, Patienten mit klassischem (cEDS) und hypermobilem (hEDS) Ehlers-Danlos Syndrom (EDS) im Hinblick auf Prävalenz und Qualität craniomandibulärer Dysfunktionen (CMD) zu untersuchen. Zusätzlich wurde der Zusammenhang zu chronischen Schmerzen und psychischer Belastung untersucht. Die EDS sind als seltene Krankheiten klassifiziert, von der nach aktueller Klassifikation 13 Subtypen unterschieden werden können (1). hEDS und cEDS zählen zu den beiden häufigsten Subtypen (1,2). Ein Charakteristisches Merkmal ist Hypermobilität der Gelenke. Laut aktueller Literatur leiden Patienten mit EDS häufiger an Kiefergelenksproblemen (3). Die hier durchgeführte Studie soll ein weiterer Schritt in der Erforschung der Erkrankung und der Entwicklung individualisierter Behandlungsmethoden sein. Methoden: Die Teilnehmer wurden über Selbsthilfegruppen in Deutschland, Österreich und der Schweiz sowie über soziale Medien rekrutiert und einem Onlinefragebogen unterzogen. Es wurden Freitextfragen zu CMD-spezifischen Symptomen sowie bereits diagnostizierten CMDs und deren Behandlung, die deutsche Version der Depression Anxiety and Stress Scale und die deutsche Version des Graded Chronic Pain Status verwendet. Ergebnisse: 259 Teilnehmer wurden eingeschlossen (230 hEDS/29 cEDS). 49,2% der Teilnehmer hatten schmerzhafte oder eingeschränkte Kieferbewegungen und 84,9% hatten Schmerzen in der Kaumuskulatur, wobei 46,3% eine bereits diagnostizierte CMD hatten. Eine Signifikanzanalyse zeigte ein 2,5-fach höheres Risiko für chronische Schmerzen bei Teilnehmern mit diagnostizierter CMD. 22% der Teilnehmer wiesen einen kritischen Wert für Depressionen auf, 53,3% einen kritischen Wert für Angst und 34,0% einen kritischen Wert für Stress. Schlussfolgerung: CMD-Probleme und chronische Schmerzen sind bei Patienten mit cEDS und hEDS weit verbreitet. Der Mangel an Wissen über diese Probleme kann zu psychischem Stress führen. Es bedarf weiterer Forschung, um Patienten mit EDS adäquat zu therapieren und individualisierte Behandlungskonzepte zu entwickeln.

Poster 2635, Sprache: Englisch, DeutschDaume, Linda / Hegemann, Pascal / Jaber, Mona / Bucklitsch, Anja / Kleinheinz, JohannesDie zahnärztliche Behandlung von Patienten mit Epidermolysis bullosa ist komplex und herausfordernd. Generell sollte eine festsitzende Versorgung angestrebt werden, da diese die fragile Schleimhaut nur gering belastet. Implantate können die Lebensqualität der oftmals jungen Patienten maßgeblich verbessern. Der vorliegende Fallbericht beschreibt die Therapie einer 19-jährigen Patientin mit Epidermolysis bullosa. Bei ihr wurden zunächst alle retinierte Zähne entfernt und Hilfsimplantate eingesetzt. Anschließend wurde Knochen augmentiert, so dass in der Folge 8 Implantate inseriert werden konnten. Abschließend konnte die Patientin festsitzend prothetisch versorgt werden.
