Background and aim: Recognizing canal configuration is necessary for a correct endodontic therapy and lack of information about canal configuration leads to failure in therapy. Since one of the most effective factors in caral configuration is race, an in in vitro and in vivo study was conducted in the city of Isfahan. The aim of this study was to recognize different canal configurations of mandibular anterior teeth and compare the clinical and laboratory results.

Materials and Methods: In the laboratory study (In vitro),314 mandibular anterior teeth were selected and then cleared. The cleared canine teeth were also studied by sectional method. The number of roots and their canals, according to the existing orifices, were recognized. In the clinical study (In vivo),415 radiographs of mandibular anterior teeth treated in graduate and under graduate departments of Isfahan University Faculty of Dentistry were selected and studied. Finally, the results of two methods were analyzed and compared.

Results: In the clearing (In vitro) method, out of 100 mandibular centrals with one root, canal configurations, based on weine classification, were type I (%69) type II (%27), type IV (%4) and type III was not observed. Out of 130 mandibular laterals with one root, canal configurations were type I( %58.43), type II (%13.59), and type IV (%0.98) and type III was not observed. Out of 111 mandibular canines, 2 of them had two toots and 109 had one root, canal configurations in this tooth were type I (%91), type II (%4.5), type III (%1.8) and type IV (%2.70). Canal configuration in this tooth by, sectional method was type I (%88.3) type II (%7.2), type III (%1.8) and type IV (%2.7). In the clinical (In vivo) method, out of 146 mandibular centrals with one root, canal configurations were type I( %78.68), type II (%10.95), and type III (%1.73), and type IV was not observed. Out of 115 mandibular laterals with one root, configurations in this tooth were type I , (%82.60) type II (%41.79) and type III (%2.61). Out of 154 mandibular canines, all of them had one root, canal configurations were type I (%95.45), type II (%2.60), type III (%1.30) and type IV (%0.65).

Conclusion: The results of this study were different from those of other researches, which could be caused by factors such as race and method. Moreover, the clinical results were different from the laboratory ones, possibly resulting from more precise laboratory studies. Additionally, considering high percentage of two canals in lower anterior teeth, more attention for the detection of the second canal, is recommended.

Key Words: Lower anterior teeth - Canal configuration.
