“…The included studies (n = 25) reported data on 25 445 teeth from 13 142 patients including 2540 maxillary first molars, 3300 maxillary second molars, 5240 mandibular first molars, 11 308 mandibular second molars, 1656 mandibular first premolars and 1401 mandibular second premolars. Evaluation included at least 4110 males and 5559 females, once six studies reported incomplete data regarding gender ratio (Yu et al 2012, Zhang et al 2015, Rogazkyn et al 2016, Pawar et al 2017, von Zuben et al 2017, Pedemonte et al 2018.

Background and aim To perform a systematic review of anatomical studies using cone beam computed tomography (CBCT) to assess the influence of demographic factors (age, gender and geographic region) on the prevalence of C‐shaped canal anatomy in maxillary molars, mandibular premolars and molars. Data sources A search was conducted between May and August 2018 in four electronic databases and five peer‐reviewed journals. The authors of included articles were also contacted for additional studies and the bibliographic references hand‐searched. Study eligibility criteria, participants and interventions The research protocol was previously registered in the International Prospective Register of Ongoing Systematic Reviews (CRD42018095201) and included defined inclusion/exclusion criteria. Prevalence studies on C‐shaped canal anatomy in maxillary molars, mandibular premolars and molars were searched. Study appraisal and synthesis methods The selected studies were submitted to full‐text analysis and critical appraisal by two evaluators using the Joanna Briggs Institute Critical Appraisal tool. The final group of papers (n = 25) were pooled and forest plots with proportions and odds ratio with a 95% confidence interval performed. Meta‐regression was undertaken to evaluate possible sources of heterogeneity and funnel plot visual analysis to assess publication bias. Results The included studies reported data on 25 445 teeth of 13 142 patients. A significant difference in the average prevalence proportion of C‐shaped configuration was observed between mandibular first (0.3%; 0.1–0.6%) and second (12%; 10.3–13.7%) molars (P < 0.05). No significant difference in the prevalence of C‐shaped configurations was observed comparing males (13.5%; 8.8–18.3%) and females (20.5%; 13.7–27.4%) in mandibular second molars (P > 0.05), although males were associated with significantly lower odds (0.573; 0.511–0.641) (P < 0.05). The pooled proportion of C‐shaped anatomy in mandibular second molars in East Asian countries (39.6%; 36.0–43.1%) was significantly higher compared with other regions. Limitations Because of the limited number of studies, no statistical analysis was performed for maxillary molars and mandibular premolars. Conclusion Meta‐analysis revealed that gender and geographic region may act as a confounding factor for the prevalence of C‐shaped anatomy in mandibular second molars, whilst age did not influence the prevalence of C‐shaped configurations in this tooth group. Knowing these preoperative factors would help to anticipate complex morphologies in clinics.

“…In general, the frequencies of Type I are very variable worldwide, ranging from 53.7 % to 88.5 % (Vertucci; Trope et al; Sert & Bayirli, 2004;Lu et al, 2006;Greco-Machado et al, 2009;Liu et al, 2013;Yang et al, 2013;Singh & Pawar;Chen et al, 2014;Sun et al;Martins et al;Pedemonte et al, 2017). Caucasoid (European) populations had the highest frequencies (Trope et al; Khedmat et al, 2010;Pedemonte et al), and Asian populations had the lowest (Liu et al; Sun et al). This study shows that the Yucatecan population falls well within the range of variability of Asian populations-51.4 % were Vertucci's Type I.…”

VEGA-LIZAMA, E. M.; TIESLER, V.; CHI-KEB, J. R.; RAMÍREZ-SALOMÓN, M.; HERNÁNDEZ-MEJÍA, A. & CUCINA, A. Root canal morphology of the mandibular first premolars in a Yucatecan population using cone beam computed tomography: An in vitro study. Int. J. Morphol., 36(4):1216-1221, 2018. SUMMARY:A successful endodontic treatment requires knowledge of the internal configuration of dental root canals. Most of the people who live in Yucatan are of Maya origin, characterized by a Mongoloid dental pattern. Because of their ethnicity, variations are expected. The purpose of this investigation is to assess the morphological characteristics and variability of this population. One hundred and five extracted first mandibular premolars of Mexican Maya population were analyzed; the sample was obtained from the Oral Surgery Clinic in the School of Dentistry at the Autonomous University of Yucatan with written informed consent. Analyses were performed by means of Cone Beam Computed Tomography. Vertucci´s Type I was the most prevalent configuration with 51.4 %, but 41 cases (39.1 %) presented a radicular groove and a C-shaped canal configuration. Overall, we documented 1, 2, 3, and 4 root canals. Mandibular first premolars are very variable in the Yucatecan population. The variability and frequency of C-shape is similar to mandibular second molars confirming the importance of the ethnic background for the endodontic treatments. VEGA-LIZAMA, E.
