ABSTRACT

Akhilesh Gurjar, Abhishek Purohit

ABSTRACT

Aim & Objectives: to compare the intercanine, intermolar and alveolar width among Class I, Class II div 1, Class II div 2 and Class III malocclusion for arch widths, the width of the maxillary and mandibular arches, gender dimorphism within groups, and gender comparisons in central India population. Methods: a cross-sectional study was comprised of patients pre-treatment study casts of 60 Class I, 40 class II div 1, 30 class II div 2 and 30 class III malocclusions. An electronic digital Vernier caliper with fine tips measuring within 0.01 mm (Aerospace) is used in this study to measure the parameters on the maxillary and mandibular study models. All subjects resided in central India with no history of orthodontic treatment. An analysis of variance test was used to compare the different malocclusion groups and genders. Result: Among the all comparison groups class I malocclusion group showed maximum maxillary inter canine, inter molar and alveolar width while class III group showed maximum mandibular inter canine, inter molar and alveolar width. Among the participants, all parameter were found increased in male subjects except for the maxillary inter canine width which is found higher in female participants. Conclusion: There was a significant difference among all malocclusion groups for the maxillary and mandibular inter canine, inter molar and alveolar width except for mandibular alveolar width. There was no gender dimorphism found within the malocclusions groups.
