Objective: To evaluate the profile changes following treatment in adult female patients with bimaxillary protrusion of Dakshina Kannada region. Materials and Methods: Twenty five Class I bimaxillary protrusive adult female patients treated with MBT appliance after first premolar extraction were included in the sample. Pre and Post treatment lateral cephalometric radiographs were evaluated and the obtained data was compared using Paired t test or Wilcoxon signed rank test. Results: Nasolabial angle showed significant increase of 7.560 post treatment (p value 0.001*) Upper lip thickness and lower lip thickness increased by 0.84mm and 0.12mm (P values 0.030*, 0.478* and respectively). Upper lip angle decreased by 7.080(p value 0.001*) Conclusion: Significant changes in nasolabial angle, upper lip angle and upper lip thickness were noticed post retraction in bimaxillary protrusive adult female patients of Dakshina Kannada region.
