A Cone -Beam C computed Tomographic Assessment of C-shaped canals in mandibular second molars in Delhi -NCR population.

Abstract

Background: The C-shaped root canal system is one example of an anatomic variation. The present study was conducted to assess the C-shaped canal in permanent maxillary and mandibular second molars in Delhi -NCR population.

Materials & Methods: 120 CBCT scans of mandibular second molars with fully formed apices and without signs of resorption were selected. Serial axial, coronal, and sagittal CBCT images were examined. The identification of a C-shaped canal and canal configuration was based on Melton et al.

Results: Out of 120 patients, males were 75 and females were 45.   The C- shaped canal was present in 30 and absent in 90 cases. The difference was significant (P< 0.05). C‑shaped canal configuration was continuous    in 62, semicolon in 41, and separated in 17 patients. The difference was significant (P< 0.05).

Conclusion: The most common C‑shaped canal configuration was continuous. The prevalence of C- shaped canals was 25%.
