This is the peer-review report for "Mothers' Knowledge of and Practices Toward Oral Hygiene of Children Aged 5-9 Years in Bangladesh: Cross-Sectional Study." Round 1 ReviewThis is an interesting piece of research [1], which highlights mothers' knowledge and practices regarding their children's oral health in Dhaka City.However, several issues made the study scientifically questionable.The major issues are as follows.The study included mothers from two hospitals in Dhaka City, but the title of the study does not mention this.The sample selection from the mothers visiting the hospitals might not represent general mothers from the whole of Dhaka.Thus, this study might not be generalizable to all mothers in Dhaka City.
