Evaluation Of Root Canal Morphology And Anatomical Relationship Of Root Of Maxillary Second Premolar To Maxillary Sinus By Cone-Beam Computed Tomography (CBCT) In Central Indian Population: The Cross-Sectional Retrospective Study

Abstract

Background: Clinician must be familiar with various pathways root canal taken to the apex. In this regard, CBCT is helpful and provides three-dimensional imaging that offers possibility to view an individual tooth in any plane.

Aims: To evaluate root canal anatomy, root canal morphology and anatomical relationship between the roots and maxillary sinus of maxillary second premolars using Cone Beam Computed Tomography (CBCT) in Central Indian Population.

Setting and Design: CBCT images of maxillary second premolars were collected from both sides of 141 patients.

Methods: Data of teeth were measured on axial, coronal and sagittal sections and evaluated properly for number of roots and canals, the morphology of canal system classified by Vertucci standard, inter-orifice distance (IOD) of canal orifices and the distance from root tip to maxillary sinus floor.

Statistical Analysis: Statistical analysis was done by using descriptive and inferential statistics using chi-square test and one way ANOVA.

Results: Of the 141 patients, 93.69% teeth are single-rooted. 30.63% of the teeth exhibited Vertucci Type I canal configuration followed by Type V configuration (29.72%), 23.42% of the teeth possessed Type III pattern. The mean Inter-Orifice Distance for multi-canal teeth is 1.6 mm. Whereas, commonest distance from root tip to maxillary sinus floor is found to be Type I ( >0.5 mm, 64.34%).

Conclusions: All kinds of canal morphology category can be detected in maxillary second premolars. IOD might be predictable factor for root canal morphology.
