Addressing Osteonecrosis: A preventable catastrophe - A multi-center study

To assess the knowledge of medical doctors about osteonecrosis who prescribe radiotherapy and bisphosphonates and dentists who receive these patients with such risk factors.

This cross sectional multicenter study was carried out from 15^th October 2021 to 20^th November 2021 in different set-ups of Pakistan. A validated and piloted questionnaire was sent to dental and non-dental doctors working in different set-ups of Pakistan through email. All data was analyzed in SPSS version 22 with p value <0.05 being significant.

A total of 400 completed responses were received. Only 58% and 67% of the participants were actively educating their patients regarding the hazards of bisphosphonate and radiotherapy, respectively whereas only 45% of the medical doctors referred their patients to dentists before prescribing bisphosphonates and/or radiotherapy. Although the medical doctors had a statistically better knowledge of the definition of osteonecrosis, overall both the dental and non-dental doctors performed poorly regarding answering the questions pertaining to definition, clinical features and risk factors. The dental doctors also showed a poor performance for more technical and in depth questions that was statistically related to lesser work experience, working in a tertiary care facility and previous exposure to such patients.

The inadequate awareness of dentists and physicians about the prevention and management of osteonecrosis of jaw is alarming. Efforts should be undertaken to raise the knowledge of dentists and physicians in this regard.
