Endodontic treatment of a maxillary first premolar with three canals: Case report

Abstract

The purpose of this paper was to report on the possibility for successful endodontic treatment of the complex case of maxillary first premolar with three roots and three canals. Systematic examination of preoperative X-rays and correct access cavity preparation were performed. Crown-down Ni-Ti rotary instrumentation technique was chosen for root canal preparation, and obturation was accomplished using resin cement and greater taper gutta-percha cones (monocone technique). This methodology contributed to efficient preparation and suitable definitive root canals obturation.

Cilj ovog rada je bio da se prikaže mogućnost uspešnog endodontskog tretmana u kompleksnom slučaju kod prvog maksilarnog premolara sa tri korena i tri kanala. Pristupilo se sistematičnoj analizi preoperativnih rentgen snimaka, kao i adekvatnoj preparaciji pristupnog kaviteta. Za instrumentaciju je odabrana krunično apeksna tehnika uz primenu Ni-Ti rotirajučih instrumenata, a opturacijaje ostvarena uz primenu cementa na bazi smole kao i gutaperka kocica veće koničnosti, monokonom tehnikom. Ova metodologija je pomogla da se izvede kako efikasna preparacija tako i zadovoljavajuća definitivna opturacija kanala korena zuba.
