Dental arch form and arch dimensions among a group of Egyptian children and adolescents

Abstract

Patients whose casts fulfilled the previously mentioned inclusion and exclusion criteria were included in the current study, to analyze dental arch dimensions in children and adolescents with normal occlusion in primary, mixed and permanent dentitions as well as detection of the most common forms of dental arches among Egyptian children.

Results showed that total lower and upper arch lengths showed increase during transition from mixed to permanent dentition. The increase in total lower arch length was from (29.19) in mixed dentition to (30.42) in permanent dentition. Likewise, the maxillary total arch length showed an increase from (32.86) in mixed dentition to (35.74) in permanent dentition
