Bisphosphonate-associated osteonecrosis of the jaw. Knowledge and attitudes of dentists and dental students: a preliminary study

Abstract

Objective: The objective was to determine the knowledge of dentists and dental students of bisphosphates and osteonecrosis of the jaw (ONJ) in the Autonomous Community of Murcia, Spain.

Material and method: A structured questionnaire was elaborated on knowledge, attitude and practice regarding aspects of the aetiology, diagnosis and prevention of bisphosphonate-associated ONJ. The questionnaire was administered to two groups: group I with 60 dental students and group II, 60 dentists with well-established professional activity.

Results: As regards the subjects' knowledge of bisphosphonate-associated osteonecrosis, 30 (50%) students and 41 (68.36%) dentists (P = 0.0041) had up to date knowledge. Most correctly identified risk factors involved. Only eight (13.33%) students and 20 (33.33%) dentists (P = 0.010) knew how to treat osteonecrosis once established.

Conclusions: Training strategies need to be established as regards bisphosphonate-associated ONJ.
