“…There is also no statistically significance between the occurrence and age group which implies that age is not a strong determinant on occurrence of C-shaped canal. This is also consistent with what reported by Zheng et al (2011) that the prevalence of C-shaped canal did not differ with age 17 .…”

Background: The recognition of unusual canal's configurations and variations are essential for successful endodontic diagnosis and treatment. This study was aimed to investigate the occurrence of C-shaped root canal in Malaysian population. Design: This is an in vitro study whereby 241 extracted human first and second molars with intact root were collected from several dental clinics in Malaysia. Materials and Methods: The roots were sectioned at three levels: subpulpal level, 3mm from apical tip and middle level between the first and last level. The appearance of the root canal sections were assessed using stereomicroscope (Leica, Germany) and pictures were taken. Data were analyzed statistically using Fisher's Exact and Binomial test with p<0.05 indicates statistically significant difference. Results: The occurrence of C-shaped canal among molars collected is 3.73%. Hundred percent of the molars with C-shaped root canal configuration are mandibular molars and 77.8% are belonged to Chinese racial. Conclusion:The findings show that C-shaped root canals do occur among Malaysian people especially Chinese racial. Besides, all the teeth that possess C-shaped root canal configuration are lower molars.

“…21 In this study, no correlation was found between gender or age and the prevalence of C-shaped canals. These data are similar to the findings of the study by Zheng et al 20 Sert and Bayirli 22 claimed that gender is an important factor to be considered in the preoperative evaluation of canal morphology for root canal treatment; however, the authors evaluated second premolars.…”

“…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.…”

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.

“…Plenty of document information studied its incidence, morphology and clinical impact [11,12]. It is reported that the prevalence of C-shaped root canals in mandibular second molars was 39% in the Chinese population [13]. Although the occurrence of C-shaped root canals in the maxillary first molars is far less than it in the mandibular second molars, the basic principles are similar when clinicians encounter such cases.…”
