Survey on maloccluslon in Iraqi dental student sample

Abstract

The aim of this survey is to investigate the prevalence of malocclusion and
different morphological features of dental occlusion in an Iraqi sample. The sample
consisted of (218) dental student at college of Dentistry, Baghdad university, aged (18-21
year) & of both sexes. Were clinically evaluated after exclusion of students who have
received any type of orthodontic treatment. The students also divided into two groups, the
group who have received extraction of any tooth and the other group who have no
extraction. Ag
,Of the sample (26.14%) had normal occlusion, (6o)05%) had CL.l malocclusion
had CL.II malocelusion and (0.45%) who had CLIII malocclusion. The )%3,77(
differences in prevalence of maloeclusion was statistically significant between these
groups. On the other hand. This statistical difference was significant in eases with
extraction than those cases without extraction (P< 0.05). clearly, there is a need for
further epidemiologeal research aiming to increase the knowledge a bout the prevalence
and type of malocclusion as well as the extent of need & demand for orthodontic treatment.
