Attachment levels and crevicular depths at the distal of mandibular second molars following removal of adjacent third molars

Abstract

The effect of root planing and curettage on the crevicular depth and periodontal attachment at the distal of mandibular second molars following removal of adjacent impacted or partially erupted third molars was evaluated in 18 patients, between the ages of 18 and 25, presenting with similar bilateral impactions. No significant difference was demonstrated in the crevicular depths and attachment levels between the curetted, root planed side, and the untreated controls. Thus, any benefits derived by root planing and curettage of mandibular second molars immediately following removal of adjacent impacted third molars are minimal. The best means of preserving periodontal attachment on mandibular second molars may be the removal of third molars at an early stage of tooth development.
