Root Canal Morphology of Permanent Maxillary and Mandibular Canines in Indian Population Using Cone Beam Computed Tomography

الملخص EN

Aim.

To investigate the root canal anatomy of single-rooted permanent maxillary and mandibular canines in an Indian population using cone beam computed tomography (CBCT).

Methodology.

A total of 250 permanent maxillary canines and 250 permanent mandibular canines were selected and scanned using CBCT.

The root anatomy of each tooth was evaluated for the following parameters: the pattern of the root canals, anatomic length of the crown and the root, the presence of accessory canals, the shape of the access cavity, the position of the apical foramina, root diameter, and dentin thickness of the root.

Results.

Majority of the teeth had a Type I canal configuration in both maxillary canines (81.6%) and mandibular canines (79.6%).

In maxillary canine the other canal patterns found were Type III (11.6%), Type II (2.8%), Type V (2%), Type XIX (1.2%), and Type IV (0.8%).

In mandibular canines the various other canal patterns found were Type III (13.6%), Type II (3.2%), Type V (2%), and Type XIX (1.6%).

Apical foramina were laterally positioned in the majority of the teeth, 70.4% and 65.6% in maxillary and mandibular canines, respectively.

12% of the maxillary canines and 12.8% of the mandibular canines had accessory canals.

Conclusion.

The root canal anatomy of permanent maxillary and mandibular canines varied widely in an Indian population.
