Root Canal Configuration of One-rooted Mandibular Canine in an Iranian Population:An In Vitro Study

Abstract

<p><strong><em>Background and aims</em></strong><strong><em>. </em></strong>A<strong> </strong>perfect endodontic treatment necessitates proper understanding of the morphology of canal and pulpal variations.<strong> </strong>This in vitro study was conducted to demonstrate the internal anatomy of mandibular canine teeth in an Iranian population. </p> <p><strong><em>Materials and methods</em></strong><strong><em>.</em></strong><em> </em>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.</p> <p><strong><em>Results</em></strong><em>.</em><em> </em>From 100 evaluated teeth, 12 (12%) had 2 canals from which 5 had type II canal configuration and 7 (7%) had type III. 88% of the specimens had one canal and none were seen to be of type IV.</p> <p><strong><em>Conclusion.</em></strong><strong> </strong>The findings of this study emphasize the importance of dentist's knowledge of variations 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.</p>
