Aim: The purpose of this study was to evaluate the efficacy of collagen resorbable membrane on wound healing after lower posterior tooth extraction The primary objective of the study was to determine efficacy of using collagen membrane on wound healing and evaluation was done on the 7th day and 30th day postoperatively using wound healing indices. Materials and Methods: The study was carried out as randomized control trial, a split mouth design, in 15 patients who were seeking extraction of bilateral lower posterior tooth. A resorbable collagen membrane was placed on the test side after extraction to promote closure of the wound. Results: We were able to establish in this study that collagen has an upper hand in the healing when compared to socket healing in the control group. It was observed that collagen group showed rapid epithelial proliferation up to day 7 compared to the control group and it was statistically significant with P<0.05. Conclusion: In the study, appreciable amount of tissue regeneration and wound healing was seen in the collagen group when compared to the control sites, thus establishing the use of collagen as a biocompatible material for socket preservation and future rehabilitation in the oral cavity.
