Abstract
OBJECTIVES: The aim of this study was to determine if the mandible (MD) experiences reductions in bone mineral density (BMD) similar to the lumbar spine (LS) and femoral neck (FN) in a postmenopausal population.
STUDY DESIGN: A total of 137 postmenopausal women underwent 3 types of densitometric examinations: LS, FN, and MD as measured in 3 regions (MD-R1, MD-R2, and MD-R3), as well as the entire mandible (MD-Net) using a dual photon bone X-ray densitometer. Densitometry of the LS and FN were performed according to the protocol of the International Society for Clinical Densitometry. Mandibular densitometry was performed using a modification of a previous technique, placing the patient in the left lateral decubitus position, with the head supported by a 13-cm-thick cushion above the temporomandibular joint.
RESULTS: Significant correlations were found between densitometry results for the LS and the MD, with P values of .021 at MD-R1 (ramus); .001 at MD-R2 (body); .050 at MD-R3 (symphysis), and .001 at MD-Net (total mandibular density). No correlation was found between mandibular and FN densitometry (P > .05).
CONCLUSIONS: According to the results, for this population, it can be affirmed that the MD responds to osteoporosis in ways similar to the LS.
