“…To our knowledge, only one study evaluated the canal configurations in a Brazilian subpopulation; the authors found a 3.5% prevalence of C-shaped canals in second mandibular molars. 15 The present investigation revealed a higher prevalence of C-shaped canals (15.3%). However, it is difficult to make a direct comparison between both studies, since the authors did not indicate the features adopted to classify the root canal as C-shaped; moreover, they did not mention where the population studied was from.…”

“…As indicated from the aforementioned studies, there is a strong relation between this type of anatomic variation and the characteristics of the population from which the sample was selected. 2,[8][9][10][11][12][13][14][15] We also encourage more studies to be conducted to determine the prevalence of anatomical variations in different ethnic groups, especially those that have not been evaluated previously.…”

“…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.

“…Despite their simple external anatomy, mandibular incisors have a complex internal morphology, and studies have reported varying anatomic features for this group of teeth (5)(6)(7)(8)(9)(10)(11)(12)(13)(14). Madeira and Hetem (5) used a tooth-clearing technique to study the root canal morphology of 1,179 mandibular incisors and reported that 11.5% of the teeth had two canals.…”

“…Recently, computed tomography (CT) was used for the observation of root canal systems (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25). CT can be applied in patients whose gender and age are identified, and without tooth extraction.…”

<b>Morphological Variations of the Root Canal System in C-shaped Roots of the Mandibular Second Molar in a Japanese Population </b>

Morphological variations of the root canal system of C-shaped roots in mandibular second molars of young Japanese patients (aged 20 to 29 years old) were analyzed by using multidetector row computed tomography (MDCT) in order to clarify the entire picture from the orifice to the apex. CT images were reconstructed so that the axial image was inclined perpendicular to the long axis of teeth. C-shaped roots were more frequently found in females (54.0%) than in males (36.7%) (p<0.01). One root canal was most frequently found on the coronal side, and the root canal numbers increased to the apex. Thus, in many cases at the coronal level the canal formed letterC , but it ramified into increasingly smaller canals towards the apex. The complex configuration of the root canals may be related to various degree of fusion in the roots. The results of this study might be used for understanding the nature of C-shaped root canals.
