Study of Mandible Features in Sudanese using Digital Orthopantomography

Abstract

Mandible being largest and strongest bone of skull having various morphological features may show changes with reference to age and sex . It very important bone to find out sex of the body remains in anthropological practice .The study amid to study mandible features and their relationship to age and gender. In present study 100 mandibles (55 females and 45 males) underwent OPG in Khartoum dental teaching hospital , by using of panoramic digital machine (vatech) .during period of September2016 to January2017. Dental subjects age group from18 to 70 years (females mean 36.55_+14.325std and males mean38.07_+15.44std) participated in this study. The measurements of condyle height , coronoid height , minimum and maximum ramus width (on both sides), are taken also observe the shape of mandiblular eroded cortex, and ccount the number of teeth on mandible . The data were obtained from panoramic radiographs :ramus width , ramus height (on both sides) were measured digitally for each subject (by using of special soft ware) . The means _+ std values of the right and left ramus height of condyle and coronoid of females was (61.627273 _+ 3.7950482 ) ,(60.341818 _+ 4.5602425), (54.230909_+ 6.3160253), (52.844 4.8223) respectivly. The means -+ std of right and left ramus height (condyle and coronoid) on males was ( 67.14444 _+ 5.2016412), (65.806667 _+4.4366449 ), (60.217778 _+ 4.7209537), (58.777778 _+ 4.3690486) respectively . The mean_+ std of maximum and minimum ramus width on right and left sides on female was (28.798182 _+ 3.7982691), (26.724 _+ 2.7532), (24.994545 _+2.5921833), (23.429091 _+ 2.4432577) respectivly. the mean _+ std of minimum and maximum ramus width on right and left side on males was (29.62000 3.1339490), (27.960000 3.808946),(25.68000 2.7147409), (23.962222 3.2981599) respsctivly. The mean _+ std of number of teeth on mandible on females was( 14.64 _+ 1.840) and on males was( 14.67 _+ 2.153) . T cortical
