Abstract

Introducion: The Human teeth have many anatomical variations and treatment of each tooth is under the influence of its configuration. Therefore, recognizing canal configuration is necessary for correct endodontic therapy, and lack of information about canal configuration causes failure in therapy. Since one of the most effective factors on canal configuration is race, we planed to have a laboratory (in vitro) research in the city of Isfahan. Materials & Methods: This study was descriptive, and was done on 160 extracted first maxillary premolars and second mandibular premolars, which were collected from a number of university clinics and private offices in Isfahan. Teeth were decalicfied, injectetd with dye, and made transparent to determine the number of root canals and their type. Finally, the teeth were additionally cut in cross sections in three points of the root and canal configurations of teeth were evaluated. The specimens were classified according to the Weine configuration by naked eye. Results: 1- In the clearing method: a) First maxillary premolars: 80 total sample size Type I (6/25%), Type II (22/5%), Type III (67/5%) and Type IV (3/75%). b) Second mandibular premolars: 80 total sample size: Type I (91/25%), Type II (6/25%), Type III (0%) and Type IV (2/5%). 2- In sectional method: a) First maxillary prmolars: 80 total sample size: Type I (2/5%), Type II (23/75%), b Type III (70%) and Type IV (3/75%). b) Second mandibular premolars: 80 total sample size: Type I (88/75%), Type II (8/75%), Type III (0%) and Type IV (2/5%).Conclusion: In other countries many researches on this subject have been done using different methods on the internal anatomy of teeth and the results are different form this study. It appears that the differences are due to genetic or race factors and methods used. Additionally, results of different studies indicate that more attention should be paid to studies on canal configuration of these teeth.
