Influence of Pre-Etched Area and Functional Monomers on the Enamel Bond Strength of Orthodontic Adhesive Pastes
and Mitsuru Motoyoshi 1,2Round 1
Reviewer 1 Report
congratulate the Authors for all the effort that they did to conduct this study. The topic is very interesting and appreciable from a scientific and clinical point of view. The study is well designed and conducted, and the manuscript is clear. There are some comments below:
The English is clear and spelled correctly
Abstract
The abstract correctly summarizes the study design and purpose.
Keywords
The keywords are correct and perfectly fitting the study design.
Introduction
The introduction is well organized and clear.
Materials and Methods
The methodology is well described and complete. The sample size and statistical procedures are correct. The Authors correctly revised the adhesive procedures better explaining this operative step.
Results
The results are clear and supported by an adequate number of figures and tables. The statistical analysis is correct.
Discussion and Conclusions
The discussion is well conducted and justified by the literature. I would add only in the discussions a reference that I attach, on all the pre bonding prophylaxis systems that I can induce an early detachment of the brackets in order to complete the manuscripy.
Pre-bonding prophylaxis and brackets detachment: An experimental comparison of different methods (2014) International Journal of Clinical Dentistry, 7 (2), pp. 191-197.
The conclusions are correct.

We appreciate your dedicated work in providing suggestions that have strengthened this manuscript. We have shown the revised sentence using Track changes.

Our response: As you suggested, we have revised the sentence in discussion and have added the literature you recommended [28]. (fifth paragraph in discussion)

Reviewer 2 Report
Very interesting work is done on the pre-etched area of orthodontic adhesive pastes. The results and discussion are well represented, drawing significant reference to the literature.
There are few minor changes that I would recommend, which would enhance the article for the readers
Line 49 - "Some Concerns" - These concerns need to be elaborated and also cited, with references or article links
Line 70 - Describe in 2-3 lines on the outline of the article, on how the remaining of the article is organized and arranged, so that readers know where to look
Figure 1 - Its a good representation of the work, but If real - actual images captured during experimentation were used, it would be better and enhance the article
Throughout the article - There is a wide amount of literature/references cited as needed in the discussion session. It is also recommended to cite the Materials suppliers in Section 2 - either a link to the website would be nice, Similarly cite the equipment used such as SEM, Instron - and the test standard is not mentioned in Section 2.1 and 2.3. Also do cite the statistical methods in section 2.5

Response to reviewer 2
We appreciate your dedicated work in providing suggestions that have strengthened this manuscript. We have shown the revised sentence using Track changes.
- "Some Concerns" - These concerns need to be elaborated and also cited, with references or article links
Our response: As you suggested, we added a sentence and literatures as follows; However, there are some adhesion concerns due to low elastic modulus and gap formation at marginal region…than previous adhesive systems [4, 5] (page 2, line 4)
- Describe in 2-3 lines on the outline of the article, on how the remaining of the article is organized and arranged, so that readers know where to look
Our response: As you suggested, we added the explanation as follows; Therefore, in order to compare their adhesive effects, the adhesion strength was examined by shear bond strength test and the adhesive state at enamel-adhesive interface were evaluated by adhesive remnant index, Knoop hardness test and scanning electron microscopy observation. (page 2, line 26)
- Figure 1 - Its a good representation of the work, but If real - actual images captured during experimentation were used, it would be better and enhance the article
Our response: We added the picture of specimen in Figure 1.
- Throughout the article - There is a wide amount of literature/references cited as needed in the discussion session. It is also recommended to cite the Materials suppliers in Section 2 - either a link to the website would be nice, Similarly cite the equipment used such as SEM, Instron - and the test standard is not mentioned in Section 2.1 and 2.3. Also do cite the statistical methods in section 2.5
Our response: 1) We have reduced the number of wide amount of literature/references [26-29] and [31-37] in discussion.
2) we have added the link of Materials supploers in Section 2.
3) The link of equipment suppliers (SEM and Instron) have also been added in Section 2.1 and 2.3.
4) As for shear bond test or Knoop hardness test, the test standards such as ISO/TS 11405 and ISO 4545 are not followed in this study because they do not target the orthodontic materials. Thus, we did not explain those test standards. We are sorry.
5) As you suggested, we have cited the literature [11] and [12] to indicate referred statistic methods.
