Strengths
Several advantages of our study include its crossover design, which serves as a control since patients serve as their own. In addition to reducing confounders such as age, gender, and hand skills among participants, it is an ideal model to estimate the period, carryover, and treatment effects.Our methodology is another strength. The brushing technique was standardized to Modified Bass, and the brushing time was standardized to 2 min, as recommended by many orthodontists [Lastly, our study was short-term, single-use trials. Short-term trials are useful in controlling confounding variables, for example, participant compliance.
