Trifid mandibular condyle is an exceptionally rare entity, diagnosed accidentally on radiographic examination. Its etiology is controversial. Dental professionals should have knowledge of this anatomic abnormality and of the problems caused by it in normal function, as well as appropriate treatment modalities. In the literature, only three such cases have been reported. The current case report (the fourth reported) is of a unilateral trifid condyle reported in a 37-year-old woman seeking treatment for a missing tooth. A panoramic radiograph accidentally revealed a discrete modification of the right mandibular condyle. Computed tomography (CT) with 3-D construction was done to confirm the diagnosis.

Purpose: Periarticular and generalized osteoporosis are well-known comorbidities of rheumatoid arthritis (RA), associated with either the disease itself or glucocorticoid therapy. This study was performed to quantitatively evaluate changes in the jawbones of patients with RA using fractal analysis (FA).
Materials And Methods: The study comprised 186 participants, including 144 women and 42 men.

Fractures of the condylar region of the mandible, although fairly common, also generate the most debate regarding management-both closed and open treatment options have been recommended and shown to yield good results. We present our experience with a minimal access retromandibular approach to fractures of the vertical mandible. This is a retrospective study of all patients who underwent open reduction and internal fixation for fractures of the vertical mandible (condyle, subcondylar region, ramus) using a retromandibular approach at a tertiary care hospital in a metropolitan city in India between January 2022 and July 2023.

Mandibular bone defect reconstruction remains a significant challenge for surgeons worldwide. Among multiple biodegradable biopolymers, allogeneic bone scaffolds derived from human sources have been used as an alternative to autologous bone grafts, providing optimal conditions for cell recruitment, adhesion, and proliferation and demonstrating significant osteogenic properties. This study aims to investigate the bone microstructure of the human scapula as a source for allogeneic bone scaffold fabrication for mandibular tissue engineering purposes.
