“…13,14,18 The Chinese population also presented high prevalence of C-shaped canals, as reported by Yang et al, 12 Zheng et al 20 and Zhang et al 5 (32%, 39% and 29%, respectively). C-shaped root and canal configurations were seldom found in Caucasian populations: Cooke and Cox, 1 Weine 7 and Cimilli et al 8 reported a prevalence of 2.7%, 7.6% and 8.1% of C-shaped canals, respectively.…”

“…13,14 A study recently conducted in the Brazilian population evaluated the root canal configuration of mandibular molars, and showed that the prevalence of C-shaped canals in second molars was 3.5%; however, the authors did not report the characteristics of its configuration, bearing in mind that the study was not limited to evaluating only the Cshaped canals. 15 Therefore, the aim of this study was to use CBCT images to evaluate the prevalence and configurations of C-shaped canals in the permanent mandibular second molars of members of a Brazilian subpopulation.…”

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.

“…Standard radiography can provide only two-dimensional images for three-dimensional objects and can only show main canals along the root, with a low probability of showing the extent of the complexities of root canal systems, for additional root canals can be missed on the radiograph (Al Nazhan 1999). To visualize the buccolingual anatomy with greater accuracy, two preoperative radiographs are made: one with a 90° angulation to the tooth in a buccolingual direction and a second at a mesial angle of approximately 20° (Seo and Park 2004). The direct digital radiography (DDR) system is now in operation clinically and, as an addition to alternative radiographic documentation, offers more benefits than conventional radiography.…”

The morphological diversity of the inner anatomy of root canals in human permanent teeth is an issue mainly described in endodontics research. In recent years, it is a relatively new point in anthropological studies because it varies by sex, geographic and ethnic circumstances. An unusual number of root canals or their specific systems can differentiate populations around the world. The multiplicity of available methods for detecting root canal systems helps to better understand their complexity; however, most cannot be applied to anthropology due to limitations that occur in the bioarcheological material. Thorough knowledge of the heterogeneity and internal anatomy of the root canals supplies numerous classification systems proposed and improved over the years by many authors. A limited number of studies in the anthropological literature and future research will shed light onto the internal tooth morphology in historical populations. The aim of this paper is to describe various classification systems of root canals applied in endodontics. However, due to the often poor state of preservation and damage of archaeological derived remains, it seems that the best method is the approach that is the simplest and least complicated.

“…The prevalence of C-shaped canals in Koreans has been reported to be as high as 32.7% and this variation is most frequently found in the mandibular second molar [9]. Although studies have reported RE or C-shaped root canals in mandibular molars, few studies have investigated the Cshaped root canal in mandibular first molar with RE [3][4][5][6][7][8][9][10].…”

In our cases, non-surgical endodontic treatment based on the results of CBCT diagnosis, ProTaper rotary system, hand instrumentation, and passive ultrasonic irrigation along with periodontal treatment resulted in long-term and successful prognosis. Therefore, CBCT analysis an effective diagnostic tool for the treatment of teeth containing complex root canals.

C‐shaped root canals of mandibular second molars in a Korean population: clinical observation and in vitro analysis

Abstract: There was high prevalence of C-shaped root canals in the mandibular second molars of Koreans. C-shaped canals having semicolon and continuous shapes at the canal orifice have a high possibility of being divided into two or three canals in the apical region.
