Occlusal variation among Sharkhan rural population

Abstract

The purpose of this study was to provide information about the occlusal variations among Sharkhan rural population and explore significant sex and age differences in occlusion. A sample of (194) subjects (117 male and 77 female) aged (12-50) year was examined. Many occlusal features were studied. The results indicate that most of the subjects had class I molar and canine occlusion, approximately (3/4) of the sample had normal overjet and correct midline relation, about (1/2) of the sample had normal overbite The most common malocclusion features was crowding in the lower anterior teeth and spacing in the upper anterior teeth followed by deep bite. While the crossbite and scissors bite were less likely to occur among the total sample. It was found the females had a high percentage of class II canine relation, and missing posterior teeth, while the males had a high percentage of class III canine relation, deep bite and upper posterior teeth rotation. With advancing age the prevalence of lower anterior crowding was decreased while the prevalence of missing posterior teeth were increased.
