Abstract

Background & Aim: The human teeth have a lot of anatomical variations and treatment of each tooth is under the influence of its configuration. The root canal anatomy, not only in various teeth, but also in one tooth might be different. The important point understands the canal anatomy that is essential for root canal therapy. One of these variations is C-SHAPED CANAL that has been mostly found in MANDIBULAR SECOND MOLARs. In various studies, different results have been reported from different regions of the world, therefore the information of each region or country is just useful for that region or country; so the present study has done to determine the frequency and Anatomic form of the C-SHAPED CANALs in MANDIBULAR SECOND MOLARs because of the lack of information about this subject in Iran.Method and Material: This study is descriptive, that has been done on 123 extracted MANDIBULAR SECOND MOLARs, which were collected from a number of clinics and private offices in Tehran. The CEJ (Cemento Enamel Junction), Mid Root and Apical cross sections have been prepared by a diamond disc and then tables on the basis of appearance of the roots and their cross sections have been provided and the results about frequency and classification of the C-SHAPED CANALs have been reported.Results: On the basis of Haddad et al classification, 17teeth have exhibited C-SHAPED CANALs (13.8% of the whole material) that 3 molars are from category I (True C-shaped) 2 are from category II and 12 have been considered as category Ill. The frequency of category II & I is 4% of the whole material.The frequency of category I & II in C-SHAPED CANAL that have more complexity and problems in treatment, is 4% of the whole material that should be considered.Conclusion: With due attention to the results of the other researches, frequency of the whole C-SHAPED CANALs in this investigation (13.8%) is between the results of the United States (west) and the results of Eastern Asia (Far East) that can prove high frequency of this kind of canals in Asian race and it's reduction towards west; further studies would be necessary to confirm this subiect.
