BACKGROUND AND AIMS: A perfect endodontic treatment necessitates proper understanding of the morphology of canal and pulpal variations. This in vitro study was conducted to demonstrate the in-ternal anatomy of mandibular canine teeth in an Iranian population. MATERIALS AND METHODS: The samples consisted of 100 extracted mandibular permanent canines. The roots of the teeth were molded in acrylic boxes. The crowns of the teeth were cut and 2 mm cross sections were made from CEJ to the apex. Sections were examined using stereomicroscope to reveal the number and location of root canals. RESULTS: From 100 evaluated teeth, 12 (12%) had 2 canals from which 5 had type II canal configu-ration and 7 (7%) had type III. 88% of the specimens had one canal and none were seen to be of type IV. CONCLUSION: The findings of this study emphasize the importance of dentist's knowledge of varia-tions in root canal morphology, since leaving a canal untreated is one of the main reasons of endodontic failures. When treating mandibular canines, the existence of a second canal should be taken into consideration.
