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: Dear Authors

1-The research topic is well-chosen, interesting and important in dental caries prevention policy and behavioral management in your context.

2. The methodology is well-designed and appropriate for the research questions followed by an acceptable data analysis

3. You have effectively integrated previous research and contextualized their work.

4. The manuscript is well-structured, which increases the readability of the article.

5. Please include the POPB questionnaire.

6. Using a translated questionnaire for study requires standardization of the translated version (translation, back translation, expert opnion...). Please explain more if you have standardized the question.

Reviewer #2: Comments regarding the manusript entitled "Oral processing behaviour and dental caries; a new relationship".

I think the manuscript is very interesting, and it provides new insights regarding the caries disease. However, there are some major concerns.

Inital lesions were not recorded, and radiographic imaging was not used, why? As the authors must know, without radiographs there will be problems with false negative outcomes. I know this is discussed in the discussion but this is truly a major issue.

DMFT was significantly higher in one of the groups, however, when looking at the individual aspects, only the M = missing was significantly higher. Is it a correct conclusion to draw that dental caries has a correlation with eating behaviours in this study? For me, it is rather oral health and not specifically dental caries that can be discussed since decayed and filled were not significantly higher in one of the groups. The limitations of the DMFT-index is that the M = missing part is always unknown regarding the aethiology.

In the manuscript, the aspect of seeking dental care is discussed, and how this affects the results. The question of seeking dental care, and specifically asking about why and what kind of care (only emergency, regular check-ups, filling therapy) should have been included in the questionnaire.

The largest limitation in this manuscript is that the fluoride aspect has not been accounted for. Toothbrushing was included in the questionnaire, but not fluoride concentrations in toothpaste, toothpaste behaviours (such as amounts of fluoride toothpaste used, rinsing with water during or after brushing), or usage of additional fluoride products. The usage of fluoride in the treatment and prevention of dental caries is of great importance, and probably affects the results in this study. This is not even discussed in the manuscript, why?

Additionally, saliva secretion rates, and buffer capacity has not been included either which is a limitation since this affects the caries risk.

Regarding supplementary information, I cannot see the pictures used in the questionnaire about food preferences, and I cannot find the questionnaire used for collecting the general information.

Reviewer #3: thank you for your work, I have a few comments to address prior to publication:

-Would it have been meaningful to include patients with minimal missing teeth or possible none to eliminate this confounding factor?

-with the information you have collected would it not have been more meaningful to perform caries risk assessment? I encourage you to present it in caries risk format if you are able to. It would simplify data presentation and make comparisons with literature easier since most studies are reporting in that way.

what is the importance of collecting plaque indices since its relationship with dental caries has proven to be weak

Dear Dr. Alazzam,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

In my perspective, your research warrants attention and publication due to the originality of its concept. In the last paragraph of the M&M (lines 255-256), however, I noticed that you mentioned about a GLM analysis but I did not find any related table or text in the result section in this regard. As you have a lot of confounding variables in your study, it is essential to perform a multivariable analysis like a binary logistic regression. Please, add a table and explain it in the text of the result section.

Fortunately, my viewpoint about the merits of your study is supported by three referees. Simultaneously, one of the referees has provided recommendations that ought to be taken into account and implemented, if feasible. Please consider and apply the comments of that reviewer as far as possible. Just, do not consider the following comment since it is completely inappropriate and not related:

• Few paragraphs should be incorporated to introduction about the details of other oral diseases and their diagnosis and treatments. suggestive reference:

Reviewer #4: Dear authors

Thanks for sharing your work with us, the following are the suggested changes and comments that should be kept in consideration:

Manuscript title: Oral processing behavior and dental caries; a new relationship.

The comments

• Both the quality and data presentation of this manuscript are acceptable and of great importance to clinicians as well as patients.

• The manuscript expands our knowledge about oral processing behavior and oral diseases including dental caries

• The title should be revised and reduced its characters ( precise & and informative)

• The abstract should reflect the content of the article and must be with range of 250-300 words.

• Three to ten keywords representing the main content of the article

• Few paragraphs should be incorporated to introduction about the details of other oral diseases and their diagnosis and treatments. suggestive reference:

Aldelaimi TN, Abood SW, Khalil AA. The Evaluation of Impacted Third Molars Using Panoramic Radiograph. Al-Anbar Medical Journal, 2010, 8(1): 26-33

Afrah A Aldelaimi, Hamid H Enezei, Tahrir N Aldelaimi, Khalil Abdulla Mohammed, Tumors of Craniofacial Region in Iraq (Clinicopathological Study), J Res Med Dent Sci, 2021, 9 (1): 66-71

• Although the results are impressive and interesting but need to be revised to be more informative by precised presentation of your finding.

• The statements in discussion are acceptable but more paragraphs about the justification of your findings and comparison with other recent relevant studies.

• Up to date references should be kept in your reference list and the old should be omitted.

Good Luck

Reviewer #2: Comments regarding: "Oral processing behaviour and dental caries; a new relationship".

The manuscript has now been revised and is much improved.

I still think the manuscript is very interesting, and it provides new insights regarding oral health related to oral processing behaviours.

I still consider the largest limitation in this manuscript to be that the fluoride aspect has not been accounted for in the method. However, this has now been addressed in the discussion. I am still concerned that excluding this factor might have provided a large bias in the study.

Additionally, saliva secretion rates, and buffer capacity has not been included either which is a limitation, since this greatly affects the caries risk. I have commented on this previously. Saliva flow rates related to oral processing behaviours his is briefly discussed in the discussion, aknowledging that there might be differences between the studied groups, but authors should recognize that the neglect of measuring this factor in current study is as a limitation.

In the discussion, (line 446 and forwards) reference 13 is used. This paragraph is confusing. The study by Liu et al 2021 does not support the statement that SPL demonstrated generally lower sweet taste perceptions compared to FPL. In the two groups of the study, Danish and Chinese test persons were compared. For Chinese individuals, the FPL:s demonstrated lower sweet taste perception compared to SPL:s, but the results were the opposite for Danish test persons. The relationship between oral processing behaviour and sweet taste perception is therefore, at least based on the referred study, not clear. I think this paragraph must be rewritten.

Reviewer #3: It is unclear where the modification have taken place. The authors response does not detail that. Kindly respond to each question in the authors response letter stating where the modifications happened in the mauscript.

Reviewer #4: • Still more recent studies should be mentioned and more paragraphs should be added to the introduction and discussion with other relevant studies

Reviewer #2: I have again reviewed the manuscript. As a whole, I think the manuscript now is suitable for publication. However, I have a few comments.

In the discussion, there is a minor language error. Line 422: “Despite being controversial [68], hard food (including apples) was found to reduce the accumulation levels of dental plaque [69]”. This statement is referring to a study, thus this should be clearly stated : “Despite being controversial [68], a study has found that…".

In contrary to the authors, I am not surprised by the findings that there was no difference in dental caries prevalence related to plaque levels. Several previous studies have shown that in general, there are only weak correlations between dental caries and dental plaque levels, except from root caries where a stronger correlation can be observed.

On line 475, a statement has been included to clarify the bias of not accounting for fluoride in the study. However, I think this statement should be rephrased (referring to the authors themselves in the text as “we” is not proper academic language).

As a side note, I must say that I am surprised that the authors have not addressed and responded to the reviewers’ questions one by one, as is expected when resubmitting a revised manuscript.

Reviewer #3: Kindly respond in detail to original comments while making the change clear in the authors response. for example: materials in methods, line 2: change is the so and so
