Ameloblastoma is a common epithelial odontogenic tumor, representing 1 to 3% of all cysts and tumors of the oral and maxillomandibular region. It has been more commonly found in the mandible than in the maxilla. Treatment of ameloblastoma is essentially surgical, ranging from conservative therapy such as enucleation, marsupialization, and curettage, to more radical approaches, including marginal, segmental, or composite resection. It has a high tendency to recur and, in some instances, has shown malignant development when treated inadequately. When resection is indicated, reconstructive measures must be considered. The aim of the present study is to report on 2 cases of large ameloblastomas of the solid/multicystic type that were treated by hemimandibulectomy and reconstructed with a novel technique consisting of a custom-made TMJ Concepts prosthesis (TMJ Concepts, Ventura, CA). The role and outcomes of custom-made temporomandibular joint prostheses in these circumstances are discussed.

Geriatric oral health care encounters significant challenges with the increase in the proportion of older individuals. Age-related changes in the dentition, muscles, and joints result in a decline in objective masticatory function, subjective restoration requirements, and acceptability among the elderly population, with individual variations influenced by systemic health. Considering functional requirements, the adaptability of stomatognathic and systemic health conditions, health economics and other factors, the authors believe that it should not be limited to the conventional "one-to-one" strategy for replacing missing teeth in geriatric prosthodontics.

Background: Approximately 30% of the adult population experiences symptoms under the concept of temporomandibular disorder (TMD). To identify patients with TMD who may require further evaluation, three screening questions (3Q/TMD) have been introduced.
Objectives: The aim of this study was to explore the prevalence of self-reported TMD and the amount of treatment received by patients in the Public Dental Service in Stockholm and how many were referred to an orofacial pain specialist.

The aim is to assess the associations of jaw functional limitation and jaw overuse behavior with pain modified by function as a required diagnostic criterion for painful temporomandibular disorders. This cross-sectional study from the TMJ Impact Project utilized secondary data analyses of 249 participants who met the inclusion criteria of having facial pain in the prior 30 days and valid responses to the pain modified by function (Items 4A-D derived from the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) Symptom Questionnaire). Independent -tests (alpha = 0.

Background: In the realm of research, the single case study has been recognized as a valuable tool for sharing insights, demonstrating new concepts, discovering novel phenomena, consolidating hypotheses, and sparking original ideas. In this physician-guided narrative, phenomena previously unreported in the clinical context are explored. These case studies aim to offer insights that may inform an existing theoretical model that encapsulates a distinct therapeutic intervention.

Article Synopsis
- The increasing number of patients with temporomandibular disorders (TMD) and the diagnostic challenges faced by general dentists highlight the need for artificial intelligence in improving TMD diagnosis.
- This study assessed a machine-learning model that classifies TMDs using patient data aligned with the International Classification of Orofacial Pain.
- Results showed the model could accurately classify joint pain at 84% and myofascial pain at 78%, indicating that decision tree-based machine learning can significantly aid in diagnosing TMD.
