Round 1

Reviewer 1 Report

Thank you for submitting this study to our journal. Here go a few concerns and suggestions:

 

  • I recommend the author to place the keywords by alphabetic order
  • I suggest to add the study design (cross-section observation study) to the title
  • The introduction is good and provides a wide specter info to the study. However I suggest the author to debate the study DOI 10.1016/j.joen.2019.10.007 which has the prevalence of missed canals in the treatments of the premolars. 
  • What was the ethnic group of the patients?
  • The title mentions Saudi sub-population. Were all patients Saudi Arabian?
  • How were the patients selected? Random? By a specific order? All in?
  • Did the authors conducted inter-rated reliability tests?
  • What visualization software was used?
  • Mentioning that the study has followed a specific checklist will increase the reliability of the study. I recommend the authors to state and adjust the manuscript to the “Preferred Reporting Items for Epidemiologic Cross-sectional studies on Root and Root Canal Anatomy using Cone-Beam Computed Tomographic Technology” and mentioning the study DOI 10.1016/j.joen.2020.03.020
  • May the authors provide the standard deviation on the prevalences in the results?
  • I suggest the authors to debate the indications of using CBCT according to the AAE
  • Please debate the study strength, generalization of the results and further studies recommendations. 
  • Please notice the references are not according to the journal guidelines.
