Abstract

Background and Aims: Successful ROOT canal therapy requires knowledge of tooth ANATOMY and ROOT canal MORPHOLOGY. For permanent mandibular premolars, great variety in size, shape and number of ROOTs and ROOT fusion expression has been reported in the literature. There is a wide variety of methods used in studies for evaluating the ROOT canal MORPHOLOGY. One of these methods is CONE-BEAN COMPUTED TOMOGRAPHY (CBCT) that reduces the limitations of two-dimensional X-ray image and with less exposure in comparison with other 3D radiographies. Thus, this study was designed to evaluate the differences in the ROOT and canal MORPHOLOGY of permanent mandibular premolars in an Iranian population by means of CBCT images.Materials and Methods: We searched a database of CBCT scans and evaluated 400 (20-60 years old) patients who met the inclusion criteria and teeth in this images (CBCT) were evaluated in three dimensions (Axial, Coronal and Sagital). Tooth length, number of ROOTs, number of canals, canal type, ROOT curvature and the effect of gender on any of the items mentioned were evaluated. Data were analyzed using T-test.Results: The average length of the first premolar of mandibular was 22.27 mm and second premolar was 22.28 mm. 98.4% of the first premolar and 98.2% of the second premolar were single ROOT., and 87.3% and 93.1% were single channel. The incidence of number of canals based on vertochy divisions were: type 1: 90.7% and 90.8%, type 0: 2.2% and 2.8%, type 4: 3.3% and 3.1%, type 6: 1.4% and 2.1% and type 3: 2.5% and 1.5% respectively. In any case, there was no significant difference between males and females (p<0.001).Conclusion: Results indicates that dentists can obtain valuable information about the ANATOMY and MORPHOLOGY of the ROOT canals using CBCT.
