The accuracy of the mental foramen position on panoramic radiographs and CBCT

Abstract

Data was analysed from 31 archived cone-beam computed tomography (CBCT) images and Digital panoramic radiographs (DP) for the same patients taken on the same x-ray machine (Carestream CS9000 3D). The position and demarcations of mental foramen were identified and then compared by means of linear measurements performed using the manufacturer provided software. Distances measured for the mental foramen in CBCT reformatted panoramic views (CRP) and digital panoramic radiographs (DP) were obtained and compared for both the vertical and horizontal positions. CBCT oblique coronal views (CORO) were studied for the vertical position of the mental foramen and compared to those obtained from CRP and DP for the same distance.
