Unlabelled: This cross-sectional study aimed to compare, by using Cone-Beam Computed Tomography (CBCT), temporomandibular joint (TMJ) morphology among patients with degenerative joint disease (DJD) with or without arthralgia, as well as a control group.
Methods: Thirty-one patients and their respective CBCT TMJ exams were assessed. These individuals were selected from an Orofacial Pain Service and classified into three groups based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD): group 1 (10 patients with TMJ DJD and arthralgia), group 2 (11 patients with TMJ DJD without pain), and group 3 (the control group, consisting of 10 healthy individuals without any signs or symptoms of TMD). A second examiner, who was calibrated and blinded for the patient's diagnosis, evaluated the CBCT images.
Results: Group 1 showed a statistically significant association with the variables of erosion (p = 0.003) and osteophyte (p = 0.04) on the condyle surface, as well as concentric condyle position with reduced joint space (p = 0.01). The Kappa concordance index between the clinical diagnosis of DC/TMD and CBCT images was k = 0.134 (p ≤ 0.001).
Conclusion: The presence of erosion, osteophyte, and concentric condyle position with reduced joint space was statistically associated with DJD and ongoing TMJ joint pain.

Background: Non-surgical method is a treatment option for mandibular condylar fracture; however, it is questionable whether bone fragments are adequately reduced and remodeled. The purpose of this study was to identify three-dimensional positional changes in the mandibular condyles in patients treated non-surgically, analyze factors influencing the extent of positional changes, and evaluate clinical prognosis.
Methods: This retrospective study included 31 patients with unilateral mandibular condylar fractures treated non-surgically at the Ajou University Dental Hospital between 2005 and 2023.
A considerable portion of the global population is affected by pulpitis and periapical lesions. While the impact of infections caused by various microbes and host effector molecules in pulpal and periapical diseases is widely recognized, disease susceptibility and progression are also influenced by the dynamic interaction between host genetic factors and environmental influences. Apical periodontitis occurs as an inflammatory response to microorganisms present in the root canals of infected teeth.

Extracellular vesicles (EVs) are membrane vesicles derived from cells and serve as an endogenous mechanism for intercellular communication. Since the discovery of their capacity to effectively transfer biological information, their potential as drug delivery vehicles has garnered significant scientific interest. Particularly, EVs derived from mesenchymal cells (MSC-EVs) have emerged as a highly promising method for drug delivery.

This study aimed to evaluate changes of the temporomandibular joint (TMJ) following maxillomandibular advancement surgery (MMA), long-term postoperative skeletal relapse, and progressive condylar resorption (PCR) development. Preoperative and postoperative cone beam computed tomography(2 weeks, 5 years) of 50 patients (33 female, 17 male; mean age 25.6 years) were assessed three-dimensionally.

Purpose: To investigate the functional and structural characteristics of temporomandibular joint(TMJ) in introverted deep overbite patients with severe wear, to analyze the correlation between the vertical distance of the lower 1/3 of the face and TMJ space, and to compare the clinical efficacy of multidisciplinary treatment with orthodontics and prosthodontics on TMJ function.
Methods: Eighty patients with deep overbite and severe abrasion and forty subjects with normal occlusion admitted to our hospital from January 2019 to June 2023 were enrolled in this study. The clinical data were collected and the functional and structural characteristics of TMJ were collected.
