Abstract
Hemisection is the splitting of a two-rooted tooth into two separate portions. This process has also been called bicuspidization in the mandibular molar because it changes a molar into two separate bicuspids. A case involving a 19-year-old patient with perforation of pulpal floor of tooth #47 and extruded gutta percha that could not be retrieved is presented. Following endodontic treatment of the distal root of #47 the tooth was hemisected and the mesial root removed. Preservation of the distal root was necessary in order to serve as abutment for restoration of the edentulous portion of mesial root and the missing #46 with fixed partial denture as tooth #48 was also missing. This article reports the procedure of hemisection of mandibular 2nd molar and its subsequent restoration with post and core in distal root of #47 followed by fixed prosthesis using #45 as an anterior abutment.
