Bisection And Bicuspidization: A Literature Review

HEMISECTION AND BICUSPIDIZATION – A REVIEW ARTICLE
Latest advances in dentistry has become a boon to patients to maintain a functional dentition for a lifetime. Retaining a teeth may involve combining restorative dentistry, endodontics and periodontics so that the teeth are retained in whole or in part. Thus tooth resection procedures are used to preserve as much tooth structure as possible rather than sacrificing the whole tooth.(1)(2)
The term tooth resection denotes the excision and removal of any segment of the tooth or a root with or without its accompanying crown portion. Various resection procedures described are : root amputation, hemisection, radisection and bisection. Root amputation refers to removal of one or more roots of multirooted tooth while other roots are retained. Hemisection denotes removal or separation of root with its accompanying crown portion of mandibular molars. Radisection is a newer terminology for removal of roots of maxillary molars. Bisection / bicuspidization is the separation of mesial and distal roots of mandibular molars along with its crown portion, where both segments are then retained individually.This is a review of various literatures citing Hemisection and Bicuspidization

Farshchian and Kaiser in their article have reported the success of a molar bisection with subsequent bicuspidization . They stated that the success of bicuspidization depended on three factors which included 1. Stability and adequate bone support for the individual tooth sections 2. Absence of severe root fluting in the distal aspect of the mesial root or in the mesial aspect of the distal root 3. Adequate separation of the mesial and distal roots to create an acceptable embrasure for effective oral
