C-Shaped Root Canal Anatomy: A Literature Review

Abstract

Recognition of unusual variations in the root canal system is critical because it has been established that the root with a single tapering canal and apical foramen is the exception rather than the rule. C-shaped canal system is a variation that has a racial predilection and is commonly seen in mandibular second molars. The intricacies present in this variation of canal morphology can pose a challenge to the clinician during negotiation, debridement and obturation. The early recognition of these configurations facilitates cleaning, shaping, and obturation of the root canal system. "C" configuration, which is an important anatomic variation, presents a thin fin connecting the root canals. Knowledge of the C-shaped canal system is essential to achieve success in endodontic therapy. Radiographic and clinical diagnoses can aid in identification and negotiation of the fan shaped areas and intricacies of the C-shaped anatomy. The aim of this review is to discuss the etiology, incidence, classification, diagnosis and management of the C-shaped canal system.

Manejo clínico endodóntico de la variación anatómica conducto en “C” tipo IV en un segundo molar mandibular

“…El diagnóstico clínico del conducto en forma de C puede reconocerse sobre la base de criterios observables definidos como la anatomía del piso de la cámara pulpar y la persistencia de hemorragia o dolor cuando se localizan los orificios separados del conducto 14 .…”
