Comparing the plaque-removal ability of a triple-headed toothbrush versus a conventional manual toothbrush in adolescents with fixed orthodontic appliances: A single-center, randomized controlled clinical trial.

The objective of this trial was to compare the plaque removal ability of a triple-headed toothbrush to a conventional manual toothbrush in adolescents with fixed orthodontic appliances. Sixty adolescent patients undergoing orthodontic treatment were randomly assigned to brush one time with either a conventional manual toothbrush or a triple-headed toothbrush. The main outcome was the post-brushing plaque index as measured by the Silness-Löe plaque index. Sixty patients (mean age, 14.2; standard deviation, 1.65) were randomized in a 1:1 ratio to either a manual toothbrush group or a triple-headed toothbrush group. Baseline characteristics were similar between the two groups. There were no dropouts. The mean post-brushing plaque index was 0.84 (95% CI, 0.67-1.02; SD, 0.60) for the conventional manual toothbrush group, and 0.31 (95% CI, 0.13-0.49; SD, 0.48) for the triple-headed toothbrush group. There was a statistically significant difference in the mean plaque index of 0.53 (95% CI, 0.28-0.78; P<0.001) between the two groups after brushing. No harms were observed. The results of this study indicate strong evidence that the triple-headed toothbrush leads to a significantly lower plaque index compared to the conventional manual toothbrush post-brushing.
