Abstract

Objectives: This study aimed to evaluate the outcomes of mandibular wisdom tooth extraction requiring bone removal at the School of Dentistry in 2023–2024. Subjects and Methods: A cross-sectional descriptive study was conducted on 42 patients with 50 impacted mandibular wisdom teeth indicated for surgical extraction with bone removal, from July 2023 to July 2024 at School of Dentistry, and the Department of Odonto-Stomatology, Hanoi Medical University Hospital. Results: Regarding intraoperative complications, the rate of fractured tooth apex was 8%, and the rate of lingual bone plate fracture was 2%. No cases of second molar mobility were noted. In terms of surgical duration, 64% of extractions lasted 30–60 minutes, 34% lasted under 30 minutes, and 2% lasted over 60 minutes. Postoperatively, 38.1% of patients experienced severe pain (level 3), and 82% had bleeding within 24 hours. The average swelling index 24 hours after surgery was 17.4 ± 5.3 mm. The rate of no new bone formation at the distal aspect of the second molar was 44%, and 38% showed bone resorption at the distal side of the second molar after 3 months. New bone formation at the distal side of the second molar after 3 months was observed in 18% of cases. Conclusions: Although removing bone to extract impacted mandibular wisdom teeth can lead to certain complications, no serious complications were observed, and this method remains a safe approach. However, larger-scale studies are required to more accurately assess the prevalence and long-term complications of this treatment method.
