The objective of this randomized crossover designed study was to compare the efficacy of plaque removal between a triple-headed toothbrush and a conventional single-headed toothbrush in 4-6-year-old children.
A total of 73 children, aged 4-6 years, were randomly divided into two groups (triple-headed toothbrush and conventional single-headed toothbrush). The children were instructed on how to use the toothbrush by watching a video clip for each toothbrush type and then brushed their teeth for 2 min. The remained plaque was recorded by Greene and Vermillion plaque index (PI). After a 3-week washout period, the toothbrush type was switched, the children brushed their teeth with the alternate toothbrush, and the PI scores were re-recorded.
Plaque scores in the triple-headed toothbrush group were statistically significantly lower than those in the single-headed group in almost all (10 out or 12) surfaces measured ( < 0.05). Plaque scores were not significantly different on the buccal surfaces of the upper posterior teeth.
The triple-headed toothbrush showed better efficacy in plaque removal and could potentially be a good alternative to the conventional single-headed toothbrush in young children with limited hand skill.
本随机交叉设计研究的目的是比较三头牙刷和传统单头牙刷对4至6岁儿童牙菌斑清除的效果。
总共73名4至6岁儿童被随机分为两组(三头牙刷组和传统单头牙刷组)。通过观看每种牙刷类型的视频片段指导儿童如何使用牙刷,然后刷牙2分钟。使用Greene和Vermillion菌斑指数(PI)记录残留菌斑。经过3周的洗脱期后,更换牙刷类型,儿童使用另一种牙刷刷牙,并重新记录PI分数。
在几乎所有(12个中的10个)测量表面上,三头牙刷组的菌斑分数在统计学上显著低于单头牙刷组(P<0.05)。在上颌后牙颊面,菌斑分数无显著差异。
三头牙刷在清除牙菌斑方面显示出更好的效果,对于手部技能有限的幼儿,可能是传统单头牙刷的良好替代品。
