Back ground: Extraction versus non-extraction is long debated topic. Decline of extraction in orthodontic treatment is observed over years. Impact of extraction and non extraction in soft tissue has been investigated for long. Aim: To study soft tissue profile changes in borderline patients treated with extraction vs. non extraction protocol. Method: 50 patients were selected for the study. Patients were divided into two groups. Group 1 consist of 25 patients treated with four first premolar extractions and group 2 consist of 25 patients treated without extraction. The pretreatment and post treatment radiographs were analyzed digitally, and seven measurements were assessed for vertical skeletal changes. Result: Mean duration of treatment observed in extraction group was 2.66+1.11 where as in non extraction group it was found to be 1.9+0.61. So in current study result showed that extraction treatment lasted significantly longer than non-extraction treatment (P < 0.01). The mean difference in Nasolabial angle observed between two groups was found to be significant (<0.005). The mean difference in Z angle observed between two groups was found to be highly significant (<0.001).
Conclusion: significant soft tissue change was observed in extraction group.
