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.
本试验的目的是比较三头牙刷与传统手动牙刷对佩戴固定正畸矫治器青少年的牙菌斑清除能力。
60名接受正畸治疗的青少年患者被随机分配,分别使用传统手动牙刷或三头牙刷刷牙一次。主要观察指标是刷牙后采用Silness-Löe菌斑指数测量的菌斑指数。
60名患者(平均年龄14.2岁;标准差1.65)按1:1比例随机分为手动牙刷组或三头牙刷组。两组的基线特征相似。无失访病例。传统手动牙刷组刷牙后的平均菌斑指数为0.84(95%可信区间,0.67 - 1.02;标准差,0.60),三头牙刷组为0.31(95%可信区间,0.13 - 0.49;标准差,0.48)。刷牙后两组的平均菌斑指数差异有统计学意义,为0.53(95%可信区间,0.28 - 0.78;P<0.001)。未观察到不良影响。
本研究结果有力表明,与传统手动牙刷相比,三头牙刷在刷牙后导致的菌斑指数显著更低。
