Περίληψη:

We describe a novel method of estimating reduced bone mineral density
(BMD) from dental panoramic tomograms (DPTs) which show the entire
mandible. Careful expert width measurement of the inferior mandibular
cortex has been shown to be predictive of BMD in hip and spine
osteopenia and osteoporosis. We have implemented a method of automatic
measurement of the width by active shape model search, using as training
data 132 DPTs of female subjects and tested on a test data set of 606
DPTs of female subjects whose BMD has been established by dual-energy
X-ray absorptiometry. We demonstrate that the sensitivity of the
automatic method to osteoporosis is equivalent to that of expert manual
measurement.
