Abstract

The aim of this study was to provide an additional information about occlusal variations, and to determine the possible sex difference in a group of young Iraqi who were seeking for orthodontic treatment.A sample of (253) orthodontically treated patients (125 female and 128 male) selected from (3719) patients attending P.O.P department in college of dentistry in Mosul University, for each one the age, sex, molar occlusion in accompanied to some selected malocclusion criteria (crowding, spacing, crossbite and openbite) were recorded. The results of this research evaluated the number, percentage for each type of molar occlusion and the malocclusion criteria. The using of two sided Z-test of twoproportions at (p<0.05) indicate that significant sex difference in CL IIb, CL II1,crowding and spacing and a non-significant difference in CL Ib, CLIu, CL II, CL II2, CL III, CLIV, crossbite and openbite. The occlusal variation for Iraqi follows a universal general distributional pattern for most world populations.

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.
