Abstract

Aim- To evaluate the root and canal morphology of maxillary first and second premolar by Cone Beam Computed Tomography (CBCT) -A retrospective study. Material and method- The following study was conducted at CBCT centre where CBCT scans of patients who were undergoing various dental treatment were evaluated. The scans were evaluated to study the number of canals and their morphology in maxillary first and second premolar. Result- Out of 120 maxillary first premolar 54 (45%) had one root, 61 (51%) had two root and 5 (4.1%) had three root. Out of 135 maxillary second premolar 110(81.4%) had one root, 20 (14.8%) had two root and 5 (3.7%) had three root. Conclusion- No significant correlation was found between root number and tooth position in both first and second maxillary premolar (P=0.35 & P=0.41 respectively for first and second maxillary premolar.
