Evaluation of the morphological changes in the mandible for dentate and totally edentate elderly population using cone-beam computed tomography

Abstract

Our study concluded that the mandibular basal bone morphology changes as a consequence of tooth loss. Cone-beam computed tomography is shown to be a good tool in investigating and achieving these results.

Three-Dimensional Analysis of Mandibular Foramen Location: A Cone Beam Computed Tomography Study

“…In our study distance to the occlusal plane is 3.47 mm in growth group while it is 7.28 mm in adult group. Due to the loss of teeth in senile ages, the size of mandible decreases and the mandibular ramus leans posteriorly, thus the mandibular angle increases [13,14]. In our study the mean distance from MF to the occlusal plane less than 7 mm after the age of 60.…”

The osseous and dental changes of patients with chronic renal failure by CBCT

“…Panoramic radiography cannot illustrate the width of the buccolingual alveolar ridge and also distorts the images. 6 Calcification of soft-tissue structures in the head and neck can present as physiological or pathological mineralization. 19 Calcium absorption in the intestines is diminished early in renal failure because the kidneys cannot convert vitamin D to its active form.…”

“…5,6,10,11 This is the first CBCT study associated with MCI measurements and other osseous and dental findings in patients with CRF. CBCT does not magnify or overlap neighbouring structures, which are inherent problems in panoramic radiography.…”

“…[7][8][9] It was shown that CBCT can also be used to determine mandibular indexes in several studies. 5,6,10,11 Panoramic radiography cannot illustrate the buccolingual width and also distorts the images. 6 CBCT is capable of providing accurate, submillimetre-resolution images in formats allowing three-dimensional visualization of the complexity of the maxillofacial region.…”

“…Mandibular bone quality can be assessed using intraoral radiographs, panoramic radiographs, CBCT, quantitative and dual-energy X-ray absorptiometry. [4][5][6][7][8] There are several radiomorphometric indices that use measurements in panoramic radiographs, which have been suggested as possible indicators of decreased value of bone mineral density. [7][8][9] It was shown that CBCT can also be used to determine mandibular indexes in several studies.…”
