Incidence of antiresorptive agent-related osteonecrosis of the jaw: A multicenter retrospective epidemiological study in Hyogo Prefecture, Japan.

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.

Impact of polypharmacy on oral health status in elderly patients admitted to the recovery and rehabilitation ward.

Aim: The oral health status of elderly adults has implications for general health problems. Polypharmacy for elderly adults is associated with an increased risk of potentially inappropriate medicines and many adverse drug events; however, no report has shown that polypharmacy itself is associated with complex oral problems. This study aimed to determine the association between polypharmacy and oral health status in patients admitted to the recovery and rehabilitation ward.
