Proposals for improvemet of the paper

Abstract 1) The study design was a cross‑sectional analytical study. 2) add the p values and confidence intervals

Methods 3) For the sample calculation, why was used the expected prevalence of 20.4% referenced in a study Klinber (2008) and ten Berg (2008)? Are there 4) what were the exclusion criteria? 5) 6-year-olds filled out the questionnaire on their own? 6) how was the calibration process of the examiners? 7) conducted pilot test? 8) the authors performed the normality and homostatic test? 9) performed the cromback alpha confiabiliade test?

Results and discuss 10) important to specify where each statistical test was used

conclusions 11) how did the inverse relationship be reached? “Untreated decayed permanent teeth have a direct relationship with dental fear, while restoration of caries has an inverse relationship with dental fear.” 12) We hope that these observations and suggestions will be useful to the authors. We reiterate the perception of the relevance of the theme, in the expectation of encouraging them to make the possible adjustments, in order for the paper to be published. Thank you for learning.
