Management of C-shaped root canal configuration with three different obturation systems

Abstract

Unusual root canal anatomy always poses a diagnostic and treatment challenge. Identification of such variation is important for the success of the root canal treatment outcome. The C-shaped root canal configuration is one of the aberrant morphology of molar teeth, commonly the mandibular second molar. In this configuration, the canals are connected by slit or web. The presence of fin, slit and web makes through debridement obstacle for the clinician. This case reports present successful management of C-shaped mandibular molars with three different obturation systems.

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

“…Las teorías sobre la morfología en forma C son diversas y las más conocidas son: la falla de la vaina epitelial de Hertwig o formarse por la coalescencia debido a deposición del cemento con el tiempo 4 . Actualmente, se sabe que el gen que da origen a raíces y conductos en forma de C es atribuido al cromosoma 5 7 .…”

“…La configuración en forma de C del conducto radicular es una de las variaciones anatómicas más importantes 4 , reciben ese nombre debido a la morfología de la sección transversal de su raíz y conducto 5 y poseen un orificio único en forma de cinta con un arco de 180° o más 6 .…”

A Case Report on Mandibular Second Molar Regarding Single C-Shaped Canal

“…4 There is possibility of tooth having single root canal. 5 The C-shaped root may also be formed by coalescence because of deposition of the cementum with time. 6 Melton et al, in 1991 classified C-shaped canals on basis of cross-section.…”

“…Following proper biomechanical preparation obturation is done with thermoplasticized obturation technique with warm vertical compaction. 5…”

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

“…[3] Amongst the different anatomical variations in the root canal systems, the unconventional and complex configuration of the C shaped roots and root canals presents with clinical adversities and challenges, compromising the objectives of endodontic therapy. [4] Cooke and Cox in 1979 first documented the C shaped configuration in root canal anatomy, which was termed owing to the 'C' shaped cross sectional anatomy of the root and/or root canal. [5] A high prevalence of C-shaped canal configuration has been reported in mandibular second molars ranging from 2.7% to 44.5%.…”
