Incidence of three canals in maxillary first premolar-a case report

ABSTRACT

This paper reports successful endodontic treatment of a maxillary first premolar with three canals. Maxillary premolars have highly variable root canal morphology, but it is rare, especially in the first premolar, to find three canals. However, in everyday endodontic practice, clinicians have to treat teeth with atypical configurations. Extra roots or root canals if not detected are a major reason for failure. Systematic examination of preoperative X-rays and correct access. Ni-Ti rotary instrumentation technique was chosen for root canal preparation, and Canals were obturated with gutta percha cones [Sure-Endo, Seoul, Korea] and Sealapex [Ken, Sybron, USA] root canal sealer using cold lateral condensation filling technique This methology led to efficient preparation and suitable definitive root canal obturation
