ABSTRACT
The treatment, management and long-term retention of mandibular molar teeth involving furcation, have been a challenge to the dental specialist. This is especially true when the furcation involvement has progressed to a Class III furcation. Successful management of such teeth requires a multidisciplinary approach involving endodontic, restorative and prosthetic interventions, especially in multi-rooted teeth. Hemisection of a mandibular molar may be a suitable treatment option when the decay is restricted to one root and the other root is healthy. Hemisection involves sectioning of a periodontally involved mandibular molar so as to remove the involved root and preserving the remaining tooth structure, alveolar bone and cost savings (time and money) over other treatment options. This article describes a simple procedure for hemisection in mandibular molar and its subsequent restoration.
