Abstract

Objective: To compare soft tissue healing, suture slack and suture removal pain between two groups silk and polypropylene after surgical removal of impacted mandibular third molar. Method: A randomized clinical trial comparing two groups with a split-mouth design was performed. Total number of 38 patients undergoing surgical extraction of two symmetrically impacted third molars with similar difficulty were involved in the study. Patients were assigned to two groups and determine the type of silk or polypropylene suture used on each side. Soft tissue healing was scored at 3rd and 7th day postoperatively. Suture slack and removal pain were recorded on the 7th day postoperatively. Results: The polypropylene group had higher soft tissue healing score than silk group on both 3rd and 7th day postoperatively. At 3rd day, the soft tissue healing score in the polypropylene group (6.32 ± 1.32) was higher than the silk suture group (5.68 ± 0.70), p=0.029. At 7th day, the soft tissue healing score in the polypropylene group (6.42 ± 1.11) was higher than the silk group (5.97 ± 0.64), p=0.029. Compared to the silk, the polypropylene had less slack (0.51 ± 0.60 mm vs 2.70 ± 0.69 mm, p<0.001) and lower suture removal pain (3.58 ± 4.25 vs. 8.29 ± 8.00, p=0.003). Conclusion: Compared to using silk, polypropylene helped soft tissue heal better, reduced suture slack and removal pain after surgical removal of impacted mandibular third molar.
