C-shaped Root Canal Clinical Trial
Official title:
C-shaped Root Canal System Prevalence and Configurations of Mandibular First and Second Molars in an Egyptian Sub-population Evaluated by Cone-beam Computed Tomography: A Cross-Sectional Observational Study
The aim of this study is to investigate the prevalence and configuration of C-shaped root
canal of mandibular first and second molars among members of an Egyptian sub-population using
cone beam computed tomography (CBCT). The prevalence and distribution of the C-shape canal
configurations with respect to gender and age will be also investigated.
Data regarding the prevalence and configurations of C-shaped root canal in the first and the
second mandibular molars in Egyptian sub-population is lacking which might affect the correct
implementation of chemo-mechanical instrumentation and obturation.
