“…When it appears as two distinct roots with a communication, the C-shaped canal may not be easily recognized on conventional periapical films. 17 CBCT makes this canal system more predictable, and is a good option clinically speaking, because it can detect Cshaped canal configurations. 5,18 Today, some studies have been using micro-CT to investigate root canal morphology.…”

Prevalence of C-shaped root canal in a Brazilian subpopulation: a cone-beam computed tomography analysis Abstract: The aim of this study was to use cone-beam computed tomography (CBCT) images to evaluate the prevalence and configurations of Cshaped canals in permanent mandibular second molars among members of a Brazilian subpopulation. CBCT exams of 214 patients (406 teeth) were evaluated for: presence of C-shaped root canals, number of canals and direction of the root grooves (buccal or lingual). Of the 214 CBCT images examined, 192 showed intact bilateral molars, which were used to analyze the distribution of unilateral and bilateral occurrences of Cshaped canals. The prevalence of these canals was correlated with gender and age, and the number of canals was correlated with the direction of the root grooves using the chi-squared test (α = 0.05). The prevalence of C-shaped canals was 15.3%. This prevalence did not differ with gender or age. Most of the C-shaped molars had three (43.5%) or two (37.1%) canals; 69.4% of the C-shaped canals were grooved in the buccal direction; 68.3% of the C-shaped cases were unilateral. In conclusion, there was a significant prevalence of C-shaped canals in the mandibular second molars of the population studied; the C-shaped canal system varied in configuration, with a higher prevalence of three and two canals and unilateral occurrence; CBCT is a useful tool for endodontic diagnosis and treatment.

“…However, anatomical configuration of roots and RCS of molars is variable [3]. Despite, there is not enough information available about morphological variations of RCS in specific to this tooth [9,10]. A possible variation is the presence of a three-rooted first molar [1,6].…”

“…Within main causes of endodontic treatment failure, has been described incomplete removing of pulp tissue and microorganisms from pulp chamber and RCS [1,3]. The causes could be a poor endodontic instrumentation technique or failure in identification of one or more root canals [2,3,5,9,10]. Thus, understanding root anatomy will contribute to improve endodontic treatment outcomes and increase success rates [2].…”

“…The importance of understanding and achieving an accurate description of both, normal anatomy and anatomical variations in teeth roots and root canal system (RCS), is relevant when dentists are going to execute procedures in zones surrounding roots and/or inside RCS. Then, exposed topics are of major interest to endodontists, considering that the main goal of endodontic treatment is to achieve a mechanical and chemical cleaning of the pulp chamber and RCS [3,5,6,9,10]. Within main causes of endodontic treatment failure, has been described incomplete removing of pulp tissue and microorganisms from pulp chamber and RCS [1,3].…”

RODRÍGUEZ-NIKLITSCHEK, C. & OPORTO, V. G. H.Determinación de la longitud de trabajo en endodoncia. Implicancias clínicas de la anatomía radicular y del sistema de canales radiculares. Int. J. Odontostomat., 8(2):177-183, 2014. RESUMEN:La endodoncia estudia la morfología y fisiología del sistema de canales de un diente. Su objetivo principal es prevenir lesiones pulpares y periodontales y tratar las ya instaladas. La determinación de la longitud de trabajo es una de las etapas más importantes del tratamiento de endodoncia. Imprecisiones en este proceso pueden favorecer la ocurrencia de accidentes y complicaciones postoperatorias. Esta revisión de la literatura describe la importancia de la anatomía dentaria aplicada a endodoncia y su estudio en cada población, además de presentar las principales técnicas para determinar la longitud de trabajo. La longitud de trabajo limita la preparación y obturación del canal radicular. Este límite debe ser la constricción apical. Diversos métodos de determinación han sido utilizados, donde el uso de localizadores apicales resulta ser el método más confiable. No obstante, es necesario conocer la morfología del sistema de canales en este proceso. Las longitudes radiculares referenciales a nivel mundial fueron publicadas por Ingle & Bakland. No existen estudios que determinen la longitud de trabajo para cada diente en población sudamericana; tampoco los hay que determinen la longitud de trabajo en pacientes con localizadores apicales. Estudiar y conocer la anatomía radicular es un requisito fundamental para un tratamiento de endodoncia exitoso. Es esperable que existan diferencias entre las descripciones anatómicas dentarias clásicas y la anatomía dentaria de poblaciones específicas. Surge la necesidad de determinar parámetros de normalidad en cada población a nivel mundial.PALABRAS CLAVE: endodoncia, raíz dentaria, tratamiento de canales, cavidad dentinaria pulpar, ápice dentario.
