Abstract

OBJECTIVE:

To retrospectively analyze the data of the patients with Bisphosphonate-related osteonecrosis of the jaw over the past five years in our hospital.

METHODS:

Twenty-four patients with bisphosphonate-related osteonecrosis of the jaw treated in our hospital from 2009 to 2013 were included. The medication, bisphosphonate types, clinical signs and symptom, treatment methods and results were also analyzed.

RESULTS:

Of the 24 cases, 20 cases suffered from malignant tumors and received intravenous infusion of bisphosphonates and 4 cases took oral bisphosphonates. Three of the 4 cases with osteoporosis had history of glucocorticoid (rheumatoid arthritis). All patients had oral clinical symptoms for an average of 11.6 months, and 19 patients had the history of tooth extraction. There were 11 cases with mandible involved, 10 cases with maxilla involved, and 3 cases with both mandible and maxilla involved. After conservative treatment (3 cases) or operation (21 cases), 10 cases had wound healing, 6 cases were stable with bone exposure, and 4 cases with died bone needed reoperation. During the follow-up period, there was one patient died of primary disease (renal carcinoma).

CONCLUSIONS:

Both intravenous and oral application routes of bisphosphonates can induce osteonecrosis of the jaw. Bisphosphonate-related osteonecrosis of the jaw can be caused by alveolar trauma. The treatment modality is to relieve the clinical symptoms of bisphosphonate-related osteonecrosis of the jaw.
