Objective:
The purpose of this study was to test a new method of dental panoramic tomogram (DPT) analysis to show the differences of mandibular bone volume and relative bone density (RBD) in order to detect osteoporosis.
Materials And Methods:
A case-control study compared 62 women with osteoporosis (O) and 24 women with osteopenia (o) to a control group of 33 women with normal bone mineral density (N). DPTs were analyzed using an original method resulting in anatomic and RBD indexes as well as using previously described methods: panoramic mandibular index (PMI) and mandibular cortical width (MCW).
Results:
One anatomic and four RBD indexes differed statistically significantly between the group O and N and three RBD indexes differed statistically significantly between o and N. PMI did not show statistically significant differences between the groups. The MCW differed significantly at two measured sites between O and N.
Conclusions:
Average values of RBD indexes were statistically significantly different between O and N and also between o and N. Important differences regarding RBD were confirmed using a new and original method of common DPT analysis. This method could serve as a screening tool for osteoporosis.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
