Perception of changes in soft tissue profile in silhouettes after face mask therapy
Keywords:Animation, ; lateral profile, perception
Introduction: Soft tissue profile marks the basis for diagnosis and treatment planning in Orthodontics. The purpose of this study was to evaluate the change in soft tissue profile after treatment with face mask therapy in Class III patients as perceived by Orthodontists, General Dentists and Laypersons.
Material and Methods: 10 patients between ages of 8-10 years, treated with facemask appliance for 12 monthsâ€™ duration were included in the study. Pre and post treatment records were taken. Silhouettes were created from lateral profile images. Sample size of 81 evaluators including 27 Orthodontists, 27 General Dentists and 27 Laypersons were asked to rate the images of pre and post treatment to quantify the change they perceived on visual analog scale.
Results: Majority preferred post treatment profiles. On quantitative analysis it was found that there was variability amongst groups.
Conclusions: Orthodontists, General Dentists and majority of Lay persons appreciate improvement in lateral profile after treatment with face mask as indicated by the fact that all groups of examiners preferred the post treatment profile silhouettes. On quantitative assessment, magnitude of these changes was found to be insignificant among all groups of evaluators.
