Maxillary Dental Arch Dimensions in a Sample of Iraqi Children at the Mixed Dentition Stage

Abstract

The purpose of this study was to estimate the maxillary arch dimensions in a selected sample of Iraqi children from Baghdad city at the mixed dentition stage, aged 8 – 9 years. Measurements were picked out from 50 study models for the whole selected sample using Auto sketch computerizing program, then The data collected were subjected to a statistical analysis. The results show that the mean values of maxillary arch dimensions of Iraqi children represent a median between North American and Indian samples. The mean values for both maxillary arch lengths and widths for the children of the present study shows lower values than that estimated from previous Iraqi studies done on older age groups, the findings of this study can be used as a basis for future Iraqi studies in other cities of Iraq rather than the capital for the same age group.
