Assessment of mandibular bone mineral density in patients with type 2 diabetes mellitus.
OBJECTIVE
To assess mandibular bone mineral density in patients with type 2 diabetes mellitus using panoramic radiographs.


METHODS
Nineteen patients with type 2 diabetes mellitus and 17 control subjects participated in the study. Bone mineral density measurements were performed on the panoramic radiographs with the help of a five-step copper stepwedge phantom, attached to each film cassette, which was calibrated before hand by dual energy X-ray absorptiometry (DXA). The analysis was performed on digitized images by dedicated software (Scion Image). The accuracy of the measurement technique was also evaluated by cross-calibration with a DXA phantom.


RESULTS
Mean mandibular bone mineral density (g cm(-2)) was 1.53+/-0.27 in women and 1.52+/-0.29 in men with type 2 diabetes. In age and gender matched control subjects the values were 1.56+/-0.28 and 1.46+/-0.23 in women and in men, respectively. No statistically significant difference was observed between groups in mandibular bone mineral density.


CONCLUSIONS
The present study showed that bone mineral density of the mandible does not seem to be affected in patients with type 2 diabetes mellitus. We also observed that a panoramic radiograph could serve for accurate mandibular bone density determination, when calibrated well with the DXA method.
