{Abstract}: <B>OBJECTIVE: </B>The purpose of this study was to determine how the surgeon's decision to perform a mandibular third molar coronectomy or surgical removal is associated with the impaction pattern as classified using Pell and Gregory or Winter's system.<BR><B>METHODS: </B>This observational, cross-sectional study was conducted on 813 mandibular third molars belonging to 565 patients. All patients were referred for removal of the mandibular third molar and had radiographic signs indicating a close relationship with the inferior alveolar nerve. Panoramic images were classified according to the impaction pattern.<BR><B>RESULTS: </B>A coronectomy was performed on 492 (60.5%) mandibular third molars. Most impacted mandibular third molars were class IIB with a mesioangular inclination. A significant association was found between the Pell and Gregory classification and the surgeon's choice (p = 0.002). Winter's classification was not significantly associated with surgeon choice (p = 0.425).<BR><B>CONCLUSIONS: </B>Mandibular third molar coronectomy is chosen more frequently than surgical removal if molars are class III and position B.<BR><B>BACKGROUND: </B>Not applicable.
