An Outlook on Dental Practices to Avoid the Oral Transmission of COVID-19

Round 1

Reviewer 1 Report

Dear authors,

thanks for submitting to “Microorganism” the paper entitled:

“An Outlook on Dental Practices to Avoid Oral Transmission of 2 

COVID-19 Infection”

the topic is original and relevant in the field. It does address a specific gap in the field especially because Covid-19 pandemic is not over.

Nevertheless, here are some suggestions to improve your manuscript.

 

Lines 129-130:

Please add a reference to support the sentence:

“That’s why people, who have a high level of saliva production, seem to have healthy teeth and low dental caries. ”

 

Lines 166-167:

The authors wrote:

“Many cross-sectional studies have suggested that patients with COVID-19 show dysbiosis of the oral microbiome ”

Please add the reference of these many cross-sectional studies.

If the authors are referring to references: 1,23,24 the authors should define them “Some cross-sectional studies”

 

Line 198:

Please do not refer to “Scientists”. Use the name of the researchers. In this case: Zheng M. et al.

 

Lines 232-233: The authors could add a link to allow the readers to download a high-resolution pdf image to use in their clinics.

 

Lines 255: please change “is” to “has”

 

Lines 271-7

The authors could emphasize even more the risks of aerosol generation during the Pandemic outbreak.

A sentence that could be added could be the following:

“Paolone et al., in a survey of 614 dental professionals, reported that increased use of preoperatory mouthwashes and rubber dam was referred during the pandemic, while aerosolization (i.e. ultrasound) was drastically reduced. The need of devices to reduce aerosol was clearly reported.”

Reviewer 2 Report

The review aimed to describe the interplay between SARS-CoV-2 infection, oral microbiome, and oral hygiene, as well as the practice to control COVID-19 in dental clinic. However, this review is still very preliminary and has a number of issues that need to be addressed.

Major issues:

1.       The authors should discuss more about the challenge and gap in the relationship between SARS-CoV-2 infection, oral microbiome, and oral hygiene.

2.       The authors should consider comparing the policy and practice to control COVID-19 in dental clinical in different countries and descript their input on those policy and practice.

3.       The authors should cite references for each statement properly, except those proposed in this article. Some of the statements which need references are listed here: Lines 53, 64, 67, 72, 76, 84, 93, 96, 115, 132 and so on.

4.       The authors should use the term of SARS-CoV-2 and COVID-19 properly. For example, in Line 34, SARS-CoV-2 should be a pathogen instead of a respiratory syndrome. In Lines 90 and 101, it should be SARS-CoV-2 instead of COVID-19. The authors should check the terms in the whole article.

5.       The author should make their statements more specific. For example: In Lines 52-53, the authors should give examples of those diseases. In Line 73, the author should describe what the “rest of the lower respiratory tract” indicated. Line 71, what did “most studies” indicate?

6.       The figure legend of Figure 1 is not accurate. First, the figure is not showing the “COVID-19 transmission” but SARS-CoV-2 viruses aspiration form oral cavity to lung. Second, The assumption has already been demonstrated (at least in partial) on an animal model conducted by a HKU team (https://www.sciencedirect.com/science/article/pii/S2666379120301634).

7.       Line 150, there have already been a lot of animal models and organoid studies which tried to address this question. The authors should summary them.

8.       Rewrite L152-164. This paragraph is confusing.

9.       Line 170-171, the statement has already been proposed by a lot of literature. The author should summary those literature.

 

Minor issues:

1.       The number of COVID-10 related death needs to be updated to a more recent data.

2.       Line 80, the “with” should be within.

3.       All the terms should be referred to by full name when they appear the first time in this article and by abbreviation afterwards. For example: “S. mutans” in Line 113, “PPE” in Line 260.

4.       A comma needs to be added after “As a result” in Line 120.

5.       Line 148, it should be angiotensin.

6.       It should be SARS-CoV-2 instead of “SARSCOV-2” in Lines 157 and 161.

7.       The grammar and spelling need to be double checked for the entire article.

General Comment: The review aimed to describe the interplay between SARS-CoV-2 infection, oral microbiome, and oral hygiene, as well as the practice to control COVID-19 in dental clinic. However, this review is still very preliminary and has a number of issues that need to be addressed.

Response: We really appreciate your support of the purpose of this manuscript. We carefully read all of your comments and have done our best to respond to each one individually. After this revision, we hope that the manuscript has been raised to MDPI in Microbiology of oral diseases standards.

Major issues:

1. The authors should discuss more about the challenge and gap in the relationship between SARS-CoV-2 infection, oral microbiome, and oral hygiene.

Response: Thank you for pointing this out. We made the required changes as recommended. Please find it in line 232-246.

2. The authors should consider comparing the policy and practice to control COVID-19 in dental clinical in different countries and descript their input on those policy and practice.

Response: Thank you for the suggestion. Here in our review paper, the goal is not to compare between different methods in different countries, we are just present the policies and procedures that have been recommended by WHO, Centres for disease control and prevention and American dental association.

3. The authors should cite references for each statement properly, except those proposed in this article. Some of the statements which need references are listed here: Lines 53, 64, 67, 72, 76, 84, 93, 96, 115, 132 and so on.

Response: Thank you for pointing this out. We made the required changes as recommended. However, sometimes several sentences are having the same references, so instead of repeating the same references after each sentence, we put the citation at the last sentence that belongs to the same references. Therefore, all the sentences before the last one will have the same citation.

4. The authors should use the term of SARS-CoV-2 and COVID-19 properly. For example, in Line 34, SARS-CoV-2 should be a pathogen instead of a respiratory syndrome. In Lines 90 and 101, it should be SARS-CoV-2 instead of COVID-19. The authors should check the terms in the whole article.

Response: Thank you for pointing this out. We made the required changes as recommended.

Response: Thank you for pointing this out. We made the required changes as recommended. Please find it in lines 52-53, line 59, and lines 57-58.

6. The figure legend of Figure 1 is not accurate. First, the figure is not showing the “COVID-19 transmission” but SARS-CoV-2 viruses aspiration form oral cavity to lung. Second, The assumption has already been demonstrated (at least in partial) on an animal model conducted by a HKU team (https://www.sciencedirect.com/science/article/pii/S2666379120301634).

         Response: Thank you for pointing this out. We made the required changes as recommended.  Please see Figure 1.

7. Line 150, there have already been a lot of animal models and organoid studies which tried to address this question. The authors should summary them.

Response: Thank you for pointing this out. We made the required changes as recommended. Please find it in lines 154-170.

8. Rewrite L152-164. This paragraph is confusing.

Response: Thank you for pointing this out. We made the required changes as recommended. Please find it in lines 141-153.

Round 2

Reviewer 2 Report

The manuscript has been improved a lot after revision, but there are still some issues:

1) L34, pathogenic virus instead of pathogen virus;

2) Figure 1 still need improvement, e.g., the dots on the top right need to be removed.

3) The use of full name and abbreviation of the bacteria is still not consistent in the manuscript, e.g., L185, Streptococcus (S.) mutans instead of Streptococcus (S) mutans; L225, abbreviation should be used for Streptococcus mutans and so on. 

4) L249, TMPRSS2 is not a receptor.

5) L250-266: The authors did not make a clear point. It seems the two animal studies do not suppot their statement.

6) L259, how to define "extremely" susceptible?

7) L463, the authors should double check if the ACE2 can break S protein?

8) L466, the author should consider describing details how bacteria directly cleavage the S protein
