Background: This study aimed to evaluate the tooth size discrepancy in patients with different types of malocclusions and compare it with that in patients with normal occlusion, using the three-dimensional (3D) measurement program Maestro Studio.
Methods and Results: Patients of both sexes who were aged between 13 and 16 years and who had never received orthodontic treatment were randomly selected. The participants’ mean age was 14.3±1.1 years; 62.0% of patients were girls. Fifty patients were divided into three groups. Group 1 included 16 patients with malocclusion Class I (controls), Group 2 included 19 patients with malocclusion Class II division 1 (II/1), and Group 3 included 15 patients with malocclusion Class II division 2 (II/2). The tooth measurements were made according to the Bolton analysis. Anterior ratio (AR) and overall ratio (OR) were calculated. There was no signiﬁcant difference in the AR between the groups. However, we found a significant difference in the OR between the groups (P=0.0129). Patients with Class II/2 malocclusion had a signiﬁcantly lower OR than patients with Class II/1 malocclusion (P=0.0155). However, there was no signiﬁcant difference in the OR between Class 1 and Class II/1 or Class II/2 malocclusions.
Conclusion: Individuals with different malocclusions show different tooth sizes.
