“…Similar results but with a statistically significant difference were found in Koreans [31], Saudis [28] and Malaysians [32]. Regarding tooth location, Cshaped canals occurred almost even on both sides in this study with no significant difference similar to reports in Chinese [4], Iranians (35), Indians [29], and Koreans [31].…”

“…C-shaped canals were found in females more than males with no significant difference same as reported in Chinese [4], Indians [29] and Iranians [8]. Similar results but with a statistically significant difference were found in Koreans [31], Saudis [28] and Malaysians [32].…”

“…Closer percentages were reported in Chileans (8.93%) [10], Indians (8.1%, 9.7%, 13.12%) [9,26,29], Sudanese (10%) [5], Belgians (10.71%) [10] and Iranians (6.7%) [23]. However, it was far lower than results in Iranians (17.6%, 21.4%) [8,24] .…”

“…MSMs with C-shaped root showed mainly both lingual and buccal grooves, followed by lingual groove only and then by buccal groove only unlike study's findings in Saudis [28], Koreans [7] and Chinese [4,21] which showed mainly lingual groove only. Moreover, Wadhwani et al [29] reported MSMs mainly with a buccal groove only in Indians.…”

Background: This study aimed to identify and characterize root and canal morphology and the prevalence of C-shaped canals of mandibular second molars (MSMs) in a Yemeni population using cone-beam computed tomography (CBCT). Methods: CBCT images of 500 right and left MSMs with mature roots were taken from 250 Yemeni individuals and analyzed for the following features: number of roots, total number of canals orifices within the tooth and number of canals orifices in each root, type of roots, either fused or separated, shape of root in cross section, type of canal configuration in each root, presence of C-shaped canal, and primary variations in the morphology of root and canal systems. Results: Molars with separated two roots predominated (89.6%), fused two roots were 9%, separated three roots were 0.6% and one root MSMs were 0.8%. Molars with three canals orifices were the most common. Mesial root was mainly ribbon-shaped (60.5%) and distal root was mainly kidney-shaped (50.7%). Type II and Type I canal configurations were the most frequent in mesial root (56.9%) and distal root (91.3%), respectively. C-shaped canals were found in 9%. Six variants were found with variant 3 was the most common (71%). Conclusions: Yemeni permanent MSMs have mainly two separated roots. Mesial root is mostly ribbon-shaped and distal root is mainly kidney-shaped. Vertucci type II and I canal configurations showed the higher incidence in mesial and distal roots, respectively. C-shaped canals were found in 9%. Keywords: Cone-beam computed tomography, C-shaped canal, mandibular second molar, morphology, root canal, Yemen

Objective: This study aimed to identify and characterize root and canal morphology and the prevalence of C-shaped canals of mandibular second molars (MSMs) in a Yemeni population using cone-beam computed tomography (CBCT). Methods: Three-dimensional digital images of 500 MSMs with mature roots were taken from 250 Yemeni individuals and analyzed for the following features: number of roots, shape and type of roots, type of canal configuration in each root, prevalence of C-shaped canal, and primary variations in the morphology of root and canal systems. Chi square and Fisher’s exact tests were employed for statistical analysis. Results: 89.6% of MSMs had two separate roots, 9% had two fused roots, 0.6% had three separate roots and 0.8% had one root. Mesial root was mostly ribbon-shaped (60.5%) and distal root was mostly kidney-shaped (50.7%). Type II and Type I canal configurations were the most frequent in mesial (56.9%) and distal (91.3%) roots, respectively. C-shaped canals were found in 9%. Six variants were found with variant 3 being the most common (71%). Conclusion: Yemeni MSMs are mainly two-rooted. The prevalence of three- and one-rooted MSMs was relatively low. Various canals configurations were found in MSMs among this sample of Yemeni population. The clinicians should consider C-shaped roots and canals when treating Yemeni MSMs and should be aware of their morphological variations to ensure successful root canal treatment. Although bilateral similarity of many anatomical features of MSMs was found, individual evaluation of each MSM is necessary while performing endodontic treatment on both sides.
