Article Overview

Aim: To evaluate components of smile among subjects with skeletal class I and class II malocclusion, in males and females.

Materials and Method: Frontal view digital photographs of 20 individuals with posed smile were divided into skeletal class I and class II and males and females. Six smile components were assessed in each photograph using Adobe Photoshop.

Statistics: Statistical evaluation was done using SPSS software (version 25.0). Pearson Chi-square test was carried out to analyze the data.

Results: For skeletal class I & II malocclusion, Smile line and Labiodental relationship had more statistically significant results. Buccal Corridor had a high statistically significant gender difference. Smile arc, Midline discrepancy, and Upper lip curvature had no statistically significant difference between malocclusions and genders.

 Non-consonant smile arc, average smile line, absent buccal corridor, presence of midline discrepancy, and straight upper lip curvature with a not-touching labiodental relationship were most frequently noted.

Conclusion: Components of smile esthetics act as guidelines for orthodontic treatment planning and help in achieving an esthetically attractive smile to satisfy patient’s expectations and to obtain successful treatment results in patients with Class I and Class II malocclusions as well as in males and females.
