CLINICAL OUTCOMES OF PTFE AND SILK SUTURES IN THE SURGICAL EXTRACTION OF IMPACTED MANDIBULAR THIRD MOLARS
Main Article Content
Abstract
Objective: To compare the clinical effectiveness of PTFE versus silk sutures in the surgical extraction of impacted mandibular third molars, focusing on postoperative pain, facial swelling, and soft tissue healing. Subjects and Methods: A controlled, split-mouth study was conducted on 34 patients requiring bilateral impacted mandibular third molar extractions at Can Tho University of Medicine and Pharmacy hospital and Hoa Su Dental clinic from July 2024 to May 2025. Results: A total of 34 patients completed the study, the mean age was 25.15 ± 5.71 years, and predominance of females (64.7%). There were no statistically significant differences between the bilaterally impacted mandibular third molars (p > 0.05). Postoperative pain levels decreased over time in both groups. On day 1, the percentage of patients reporting no pain was 41.2% in the PTFE group versus 35.3% in the Silk group. By day 7, the majority of patients were pain-free, with 94.1% in the PTFE group and 88.2% in the Silk group, however, the difference was not statistically significant (p > 0.05). Facial swelling, evaluated using three linear measurements, peaked on day 1, gradually decreased by day 7, and showed no significant differences between groups at any time point (p > 0.05), although the PTFE group tended to have less swelling. Regarding soft tissue healing, the PTFE group showed significantly higher healing scores on day 3 (mean 4.0 ± 0.9 vs. 3.3 ± 0.8 in the Silk group; p < 0.05), indicating faster early tissue recovery. By day 7, both groups achieved high healing scores, with no significant difference (p > 0.05). Conclusion: PTFE sutures demonstrated superior performance in promoting early soft tissue healing compared to silk sutures, while providing comparable control of postoperative pain and swelling. PTFE may be considered a favorable alternative in clinical practice for impacted third molar surgery
