Characterizing of normal Mandibular Bone Structures Using Three Dimensional CT Image

Abstract

Mandible is largest and strongest bone of skull, having various morphological structures and features show associated changes according to age, gender for human.

The aim of this study is to characterize the mandible and to find out it has relation with age and gender of the human and establish local reference for the Sudanese mandible measurement and compare these measurements with other population by using CT scan 3D imaging and applying axial

section projection as well as sagittal section for CT facial protocol. 160 patients were selected to participate in this study by choosing 92 men with a mean of age is (21-49) years and 68 women with a mean age of (23-45).

The result of this study showed that the measurement of bi condylar breadth of the mandible were differ between males and females and the males have greater measurement mean (115.24mm) than females mean (109.81mm),while The mandibular symphysis height mean was greater in females (35.76 mm) than males (34.30 mm). The study was showed that in Sudanese population the bi bicondylar breadth and mandibular body length measurement change significantly with increasing age Comparing with other populations in addition to that the mental foramen width mean in right side is (4.29mm) and left side is (3.53mm), This was considered to be greater measurement than other previously studied populations. Since, if Sudanese people their ages or gender were known, new equation will be establish in order to standardize a local reference for mandibles and mental for a means measurements.
