Background/purpose: The incidence of medication-related osteonecrosis of the jaw is increasing worldwide, mostly due to the use of antiresorptive agents (ARAs) such as bisphosphonate (BP) and denosumab (Dmab). However, the proportion of BP-related osteonecrosis of the jaw (BRONJ) and Dmab-related osteonecrosis of the jaw (DRONJ) among all ARA-related osteonecrosis of the jaw (ARONJ) cases is not clear; this hinders appropriate treatment, recurrence-prevention planning, and avoidance of unnecessary Dmab withdrawal. Moreover, the causative drug administered at each disease stage remains unknown.

The patient had a history of tongue carcinoma and had undergone a radical neck dissection for the treatment of gingival carcinoma. She underwent combined chemotherapy consisting of S-1 (80 mg on days 1-14, followed by a 7-day rest), docetaxel (35mg/m2 by intravenous infusion on days 1 and 8), and CDDP (10mg/m2 by intravenous infusion on days 1 and 8) every 3 weeks.

Purpose: Aging is clinically related to tooth eruption; however, there are no known studies that have elucidated the relationship. We examined whether tooth eruption would occur normally in a mature subject.
Materials And Methods: Using vascularized composite tissue mandibular transplantation, we extracted portions of immature mandibles including the tooth germs from young beagle dogs and placed them into unrelated immature and mature beagle dogs.
