Article Abstract
Background: Some odontogenic cysts (OCs) and odontogenic tumors (OTs) are infiltrative and often recur, causing bone destruction and tooth loss. In the elderly, in particular, these injuries cause significant morbidity, making rehabilitation difficult and compromising the quality of life of these individuals. Objective: To determine the prevalence and demographic characteristics of OCs, non-odontogenic cysts (NOCs), and OTs diagnosed in an elderly Brazilian population (≥60 years).
Material And Methods: A retrospective descriptive cross-sectional study was carried out in three Brazilian pathology referral centers (1999-2019). Data regarding age, sex, ethnicity, anatomical location, symptomatology, and histopathological diagnosis were obtained from histopathological records and analyzed. Pearson's Chi-squared and Fisher's exact tests were used to evaluate the association between the different groups of oral lesions and demographic findings, adopting a P-value of ≤ 0.05 and a 95% confidence interval.
Results: A total of 7,476 histopathological records were evaluated, of which 389 (5.2%) cases were classified as OCs, 86 (1.15%) as NOCs, and 83 (1.11%) as OTs. The most common lesions in each group were periapical cysts (n=166; 68.9%), ameloblastomas (n=65; 77.4%), and salivary duct cysts (n=45; 52.3%). Overall, males were slightly more affected (n=279, 50.2%). Most individuals were between 60 and 69 years (n=358; 64.2%). OCs and OTs preferentially affected the mandible (n=280; 62.2%). NOCs occurred more frequently in the lips (n=19; 22.1%), followed by buccal mucosa (n=18; 20.9%). The overall concordance between clinical and histopathologic diagnoses was 47.2% (213 of 451 cases).
Conclusions: OCs were relatively common, whereas NOCs and OTs were rarer among the elderly. The low concordance between clinical and histopathological diagnosis highlights the importance of histopathological analysis to ensure an accurate diagnosis. Dentists and geriatricians must be familiar with these lesions to ensure an early diagnosis, reduce morbidity and improve the quality of life of these individuals.

The association between genetic syndromes and odontogenic tumors encompasses several entities, reflecting the intricate interplay between genetic factors and the development of these lesions. The present study aimed to comprehensively investigate the associations between genetic syndromes and odontogenic tumors. We delineated the diverse spectrum of syndromic connections, including key syndromes such as Gardner syndrome, Gorlin syndrome, Schimmelpenning syndrome, and others.

Ameloblastoma (AM) is a benign but locally infiltrative epithelial odontogenic neoplasm of the jawbones that may reach grotesque proportions and be highly recurrent if inadequately removed. The BRAF mutation has been demonstrated as key molecular event in its development, nevertheless, there are many queries about its aetiopathogenesis that are yet to be answered. In this study, we aimed to integrate results from whole-exome sequencing (WES) and RNA-sequencing in AM samples to identify novel candidate genes that may be relevant to its pathogenesis.

Odontomas are the most prevalent odontogenic tumors, often classified as hamartomas due to their slow growth and non-aggressive nature. Typically asymptomatic, they can obstruct the eruption of adjacent teeth. While the exact causes of odontomas remain unclear, potential factors include local trauma, infection, growth pressure, and hereditary influences.

Objective: and rationale: Odontogenic myxoma is an uncommon odontogenic tumor with locally aggressive behavior. The clinicopathological studies of odontogenic myxoma in Asian countries are very limited and only few studies have investigated the immunohistochemical profiles of the tumor. This study aims to investigate the clinicopathological and immunohistochemical features of odontogenic myxoma at the Faculty of Dentistry, Mahidol University over a 15-year period.
