Abstract

Teeth once designated obsolete for rehabilitation and deemed for extraction should be re-evaluated for salvaging two thirds or even one third component of the individual teeth. Advances in dentistry, as well as the increased desire of patients to maintain their dentition, have lead to treatment of teeth that once would have been removed. In order to carry out this present day mandate, periodontally diseased teeth with severe bone loss and/or mandibular molar teeth exhibiting furcation invasions may well be retained by removal of one or more of their roots. This article describes a simple procedure for root amputation in mandibular molar and its subsequent restorations. DOI: http://dx.doi.org/10.3329/updcj.v1i1.13949 Update Dent.

Highlights

In 1960's, the therapy involving root amputation was right on the cutting edge in both periodontics and endodontics
GV Black described almost the same methods in the nineteenth century and by sharp in 1920.1 With improvement in the dental procedures and materials in both periodontics and endodontics leading to more sophisticated therapy, teeth at marginal prognosis has provided the opportunity for patients to maintain a functional dentition for life time
Therapeutic measures performed to ensure retention of teeth vary in complexity.The treatment may involve combining dentistry, endodontics and periodontics so that the teeth are retained in whole or in part

Summary

Introduction

In 1960's, the therapy involving root amputation was right on the cutting edge in both periodontics and endodontics. Therapeutic measures performed to ensure retention of teeth vary in complexity.The treatment may involve combining dentistry, endodontics and periodontics so that the teeth are retained in whole or in part. Such teeth can be useful as independent units of mastication or as abutments in simple fixed bridges or individual crown with sufficient rest support. Hemisection denotes removal of separation of root with its accompanying crown portion of mandibular molars. Bisection or bicuspidization is the separation of mesial and distal roots of mandibular molars along with its crown portion where both segments are retained individually.[1] Weine[1] has listed the following indications for tooth resection.

Vertical fracture of one root

Severe destructive process
