Awareness Of Medical Doctor On Medication-Related Osteonecrosis Of The Jaw In Osteoporosis Patients, Nachapol Supanumpar
Chulalongkorn University Theses and Dissertations (Chula ETD)
Antiresorptive drugs are widely used to treat osteoporosis. A serious adverse effect of these drugs is medication-related osteonecrosis of the jaw (MRONJ). By informing and educating patients about MRONJ, providing proper dental referral, and monitoring the oral health of patients who receive antiresorptive agents, physicians can reduce the risk of MRONJ. We investigated the awareness and clinical practices of physicians in Thailand with regard to MRONJ. Physicians who prescribed antiresorptive drugs for osteoporosis filled out an online self-administered questionnaire about demographic characteristics, awareness, and practices related to MRONJ. Most respondents agreed that antiresorptive drugs may cause MRONJ (92.3%), that poor …
