| Abstract Objective: The aim of the present study is to assess impacted lower third molar coronectomy through vestibular bone window. Subject and Methods: Twenty patients were allocated into two groups. In group 1, the standard coronectomy technique was performed while in group 2, coronectomy through vestibular bone window was done. Preoperative evaluation included examination of the site of surgery for the presence of inflammation, ulceration, discoloration or infection and measurement of the crevicular depth, maximal mouth opening and cheek dimension. OPG and CBCT were used to give full details on tooth and its relation to IAN. Results: Out of 20 patients only one (5%) had IANI. The mean crevicular depth was significantly less in vestibular window group than regular coronectomy. The mean MMO was larger in vestibular window group than regular coronectomy, the difference was nonsignificant. The mean cheek dimension was less in vestibular window group than regular coronectomy, the difference was nonsignificant. The mean VAS value was higher in group 2 than group 1; however, the difference between the two groups was nonsignificant. Conclusion: Coronectomy is a safe technique that greatly reduces the risk of IANI. Coronectomy through vestibular bone window technique may reduce periodontal pocket formation distal to the lower second molar. Vestibular bone window technique has no effect on postoperative sequelae (trismus, swelling and pain). | ||||
