Microbiological Evaluation of Water Used in Dental Units
Round 1
Reviewer 1 Report
The authors have investigated the presence of micro-organisms in different component parts of a dental unit. Their special attention was water that dentists use during the dental treatments.
The introduction section is well written with enough background information which leads it to the goals of this study. However, I felt that introduction was ended abruptly. I would suggest you add a line or two after line 123 to mention very briefly the reasons of this study. You have mentioned the goals (what are you doing in this study) but didn’t mention what will come out of the findings.
Line 145: counted by what?
Section: Materials and methods: You could divide this section in to two parts a) Sample collection b) analysis. It should read better doing that. Otherwise, this section has enough details.
The results section is also well written with proper presentation of data through Tables.
Line 256-257: Revise this sentence.
Discussion section can be divided in least two subsections for better reading. There should a subsection for the recommendations based on your findings.

Answer: We would like to thank you for the comment. Additional information has been added to the manuscript.
Question 5
Line no-180: Please summarize the major pathogen only, and make a table of these bacteria isolated from samples of major units at the annex.
Answer: When discussing the results, the authors mention only the most frequently isolated species. 10 strains appear with a frequency of 24-1.5%, and 17 other strains occur with a frequency below 1%. The pathogenicity of all isolated microorganisms is presented in Table 3. According to the authors of the study, it is important to present all types of microorganisms grown from the collected samples. The pathogenicity of the mentioned microorganisms is presented in Table 3.
