Management of the Diagnostic and Therapeutic Obstacle to Successful Endodontics in C Shaped Canals: A Case Series

Abstract

Comprehensive knowledge of the anatomy of the root canal system is of paramount importance in successful
endodontic treatment. It has been stated that a single tapering canal with a single apical foramen is an
exception rather than a rule. Hence, awareness of unusual morphologies in the canal system is critical
for favourable outcome of treatment. Efficacious biomechanical preparation and obturation depends upon
the timely identification of the root canal system. An important variation of the root canal system is the
C shaped canal configuration. It presents with a fine fragile fins or webs joining the root canals causing
inadequate debridement of the root canal system compromising the prognosis of treatment. This case series
presents successful diagnosis, accurate radiographic visualisation of microanatomy using contrast media and
management of four cases of C?shaped mandibular second molars with different morphological variations.
