Abstract
Background: Effective removal of plaque depends not only on the correct brushing technique but also on the type of toothbrush used.
Purpose: This clinical trial was designed to clinically compare the U-shaped manual toothbrush and the regular toothbrush in reducing microbial plaque in children aged 5–7 years.
Materials and Method: This randomized clinical trial study was conducted on the one hundred children aged 5–7 years. The participants were asked not to brush their teeth for 24 hours. The amount of plaque accumulation was assessed by two blinded examiners using the plaque index at two-time intervals. Initially, the baseline plaque index was recorded (T1). The participants were randomly divided into two groups (n=50). The children in the first group were taught the correct use of the U-shaped toothbrush, while participants in the second group were taught the horizontal scrub technique. The children in both groups brushed their teeth with the same toothpaste for two minutes, after which the plaque index was recorded (T2).
Results: In both groups, the mean plaque index after using the toothbrush decreased compared to baseline (p Value<0.05). The reduction in the mean plaque index in the U-shaped toothbrush group was significantly greater than that in the regular toothbrush group (p<0.05).
Conclusion: When children brushed their teeth independently, the U-shaped toothbrush was more effective than the regular toothbrush in removing dental plaque.
