Round 1

Reviewer 1 Report

The present study aimed to assess the need for orthodontic treatment, as well as the possible existence of differences in gender or socioeconomic status of the studied population. The data obtained are likely to help plan the local health care system to plan resources for timely and high-quality care for this patient population.

1. I would like the authors to more clearly reflect on the period in which the study was conducted. It would be helpful to indicate the recommended frequency of such epidemiological studies for dental practitioners. This will strengthen the value of conducted work.
2. In the materials section, the authors point to a periodontal probe and a mirror as the instruments used. Perhaps we are talking about a pair of sterile instruments for each patient. The protocol of infection control of the study raises doubts about its ethics, in particular, the examination of children in classrooms, and thus I would like to receive detailed comments from the authors on this issue.
3. The approval for publication from the patients who participated in your study is mandatory. Please provide a blank form of consent for publication.
4. As the paper reports the result of a randomized controlled trial, but does not include the randomized controlled trial registration number. Your manuscript should include the international clinical trials register and cite a reference to the registration in the Abstract and Methods section.
