Hemisection and Partial Retention of Carnassial Teeth in Client-Owned Dogs

Abstract

Nine client-owned dogs presented with periodontally and/or endodontically involved mandibular or maxillary carnassial teeth that were either individually affected or adjacent to a jaw fracture. A total of 10 teeth were hemisected (8 mandibular first molar teeth and 2 maxillary fourth premolar teeth), and one crown-root segment was extracted for each tooth. Gingival tissues were approximated and sutured over the extraction sites, and the retained tooth portions were treated by means of standard root canal therapy or vital pulp therapy followed by standard root canal therapy. Retained crown-root segments of 2 of the 10 hemisected teeth were extracted following short- and long-term postoperative examinations due to continued periodontal complications. It was concluded that resection of a portion of a tooth can be a useful treatment for periodontally and/or endodontically involved carnassial teeth that are affected individually or located adjacent to a jaw fracture in dogs.
