The risk of bisphosphonate-related osteonecrosis of the jaw in children. A case report and literature review.

UNLABELLED Bisphosphonate use has been described in children diagnosed with osteogenesis imperfecta (OI), fibrous dysplasia, neuromuscular disorders, bone dysplasia, idiopathic juvenile osteoporosis, rheumatologic disorder and even Crohn's disease. In OI patients, bisphosphonates have become an important symptomatic therapy for moderate and severe forms of the disease, because their inhibitory effect on osteoclasts increases bone mineralization and density, thereby reducing the risk of bone fractures. Bisphosphonate-related osteonecrosis of the jaw (BRONJ) has become an increasingly common complication as the use of these drugs is becoming more widespread in adults. However, the evidence for BRONJ in paediatric patients is scarce. We present a case of a patient with OI on IV bisphosphonate therapy who required dental extractions and review the literature of the risk of BRONJ in this group of patients. CLINICAL RELEVANCE Dental clinicians need to be aware of the potential risk of BRONJ in paediatric patients who have had intravenous bisphosphonate therapy. It is important that these patients are identified and managed appropriately.
