5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Çapan reported on YouTube videos on space maintainers, and evaluated the efficiency of videos by parents and patients. The manuscript is overall clear, and methods are sound. I only have some minor suggestions to the authors.

In the “Selection and Analyzes of Videos” section, the author mentions two authors reviewed the videos. However, in the current version of the manuscript, there is only one author. Please, double check whether all authors have been correctly added to the submission system.

It is not clear who actually scored the usefulness. Considering the objective of the study, it would be perhaps helpful multiple rating from healthcare professionals and parents. If this is not the case, authors should consider this as a limitation of the study.

I would recommend author adds a study flow diagram with number and reasons for exclusions for all YouTube videos.

In table 3 some rows look empty. Could you please double check and remove any useless rows?

In the discussion, authors should specifically comment on the active role healthcare providers should play on social media in order to provide complete and balanced information (e.g., Lavorgna et al. Mult Scler Relat Disord 2018; Lavorgna et al. Front Neurol 2020).

Reviewer #2: In this study çapan assessed the content of YouTube as an information source on space maintainers and evaluated the efficiency of videos by parents and patients. 

There are some minor revision needed, given in the specific comments below.

1. It is unclear in the paragraph "Usefulness and viewers' interaction" what the author means with "and 9 rated video".

2. If all very useful videos were uploaded by healthcare professionals or professional organizations, table 3 not is correct. It showed that 1 useful video was uploaded by Health information Web sites and not by healthcare professionals or professional organizations. Moreover, always in Table 3, the total numbers of videos do not correspond to the sum of each category. Maybe some rows are empty.

3. In light of the findings revealing that all very useful videos were uploaded by healthcare professionals or professional organizations, the author should discuss widely the relevance of the role of health care providers in uploading and supervising the health related information on online platforms.

**********
