[Association between bone mineral density of the general skeletons and jaw bones]

Associations between bone mineral density (BMD) of the general skeletons and jaw bones have been investigated to clarify the influences of skeletal low BMD or osteoporosis on periodontitis and tooth loss, especially in women. Some studies reported the significant associations between general skeletal BMD and BMD (or bone mass) of the jaw bones, however, the others failed to find this association. It is likely that the differences in the methods and regions in measuring BMD (or bone mass) of the jaw bones and in study sample size may contribute to this contradiction. Further systematical investigation in the large populations would be necessary in cooperation with medical professionals.
