Title

Anatomic Features of C-shaped Mandibular Second Molars in a Selected Iranian Population Using CBCT

Pages

  120-125

Abstract

 Introduction: The aim of this retrospective study was to analyze the frequency of C-shaped root Canal Configuration and characterize mandibular root canal morphology using Cone-beam Computed Tomography (CBCT) with 3D images in an Iranian population. Methods and Materials: This study consisted of retrospective evaluation of CBCT images from 231 adult patients (153 with bilateral second mandibular molars). Two endodontists examined 384 Mandibular Second Molars of a population in Tabriz, Iran to determine the presence of C-shaped Canals and their anatomical characteristics. Root Canal Configurations were categorized at three different levels. Bilateral or unilateral occurrence of C-shaped Canals and their relationship to gender, age and tooth position were examined and statistically analyzed using chi squared test and Fisher’ s exact test in SPSS 17. The significance level was set at 0. 05. Results: Of 384 Mandibular Second Molars examined, 82 (21. 4%) molars from 58 patients had a C-shaped root Canal Configuration. The prevalence of bilateral C-shaped Canals was 15. 6% amongst 153 patients with bilateral Mandibular Second Molars. There were no significant differences in the distribution of C-shaped Canals with respect to gender or age (P=0. 06 and P=0. 86, respectively). Only 4 teeth (4. 9%) had the same root Canal Configuration from the orifice to the apex. In the remainder of the teeth, the cross-sectional root Canal Configuration changed at different levels of the root. Conclusion: There were significant variations in the number of roots and canal morphology in Mandibular Second Molars, which should be considered during debridement and obturation of the root canal system.
