Abstract

Background: Impacted mandibular wisdom teeth often cause complications such as gingivitis, abscesses, cellulitis, osteomyelitis, and sepsis, necessitating extraction. This common procedure carries a complication rate between 4.6% and 30.9%, including damage to adjacent teeth and tissues, jaw fractures, swelling, pain, trismus, dry socket, and infections. Selecting an appropriate surgical method is crucial to minimize these risks. Objectives: To evaluate outcomes of partial versus complete closure techniques in mandibular wisdom tooth extraction. Materials and methods: A crosssectional descriptive study with clinical intervention and control group was conducted on 70 patients with Class II A mandibular wisdom teeth, according to Pell and Gregory classification, at Can Tho University of Medicine and Pharmacy Hospital from May 2023 to March 2025. Results: The mean operative time for the partial closure group (14.83±1.6 minutes) was significantly shorter than that of the primary closure group (19.37±2.3 minutes) (p<0.001). The partial closure group also reported significantly lower pain scores on postoperative days 1, 3, and 7 (p<0.05). Horizontal and vertical facial swelling significantly increased on days 1 and 3 postoperatively but gradually subsided to near baseline by day 7 (p<0.001); vertical swelling difference was not statistically significant on day 7 (p=0.084). Conclusion: These findings highlight the advantages of partial wound closure in reducing surgical time, postoperative pain, and facial swelling following the extraction of impacted mandibular third molars classified as Pell and Gregory class IIA.
