Introduction: Teeth may need root canal treatment for various reasons. The anatomy of the root canal varies not only between different types of teeth but also between similar teeth. Although there must be at least one canal in the root, some roots have multiple canal of different length. The goal of this study was investigation of the number of root canals in mandibular molars and premolars teeth in Ilam in 2020.
Material & Methods: This study was descriptive-analytic study that performed on 60 mandibular premolars and molars (first premolars 15, second premolars 15, first molars 15, second molars 15) randomly with considering of the sex of patients. Data were analyzed by SPSS22.
(Ethic code: IR.MEDILAM.REC.1399.064)
Findings: In the first and second premolars, the highest frequency of single canal as 86.7% and 93.3%, respectively. In the first and second molars, the highest frequencies related to the three channels were 53.3% and 86.7%, respectively. The prevalence of 4-channel molars was higher in women and 3-channel in men. This difference was not statistically significant. Between two radiologists and endodontists to determine the number of root canals in the first and second premolars and the first and second molars, a good agreement was reported with kappa agreement coefficient of 0.92 and (P = 0.000).
Discussion & Conclusion: According to the results of the present study, the first and second mandibular premolars had mostly single root and one canal, and the first and second mandibular molars had often   two roots and three channels.
