Abstract

Aims: This study aimed to evaluate the orthodontic treatment needs of children aged 12–14 years using the dental health component (DHC) and aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN). Methods: A total of 407 children who presented to the Pediatric Dentistry Clinic of Batman University Faculty of Dentistry were included. IOTN-DHC and IOTN-AC scores were recorded. The distribution of treatment needs by sex and age was analyzed using the chi-square test. The relationship between AC and DHC was evaluated using Spearman correlation analysis. Statistical significance was set at p0.05). A positive, moderate correlation was observed between AC and DHC (r=0.722; p
