Abstract
Medication-related osteonecrosis of the jaws (MRONJ) still is increasing in Japan according to the reports from the Japanese Society of Oral and Maxillofacial Surgeons at 2022. New MRONJ Japanese position paper released at 2023 emphasizes cooperation between physicians and dentists to prevent MRONJ. Japan Osteoporosis Society (and Adequate Treatment of Osteoporosis Research Group) conducted questionnairebased survey regarding cooperation between them at 2014, 2015 and 2018. We investigated new questionnairebased survey at 2022 and compared the results at 2022 with those of previous surveys. The rates of physicians who requested oral health care by a dentist before antiresorptive agent therapy and reported cooperation between physicians and dentists were 72.7％ and 42.4％ in 2022 compared with 32.9％ and 24.8％ in 2015, respectively. The rates of cooperation among the 47 prefectures in Japan were significantly different, ranging from 10.0 to 83.3％. A further increase of a similar magnitude in cooperation across Japan would be necessary to prevent MRONJ.
