This study investigated the brushing times and patterns of two groups of children who used either a translucent gel dentifrice or a conventional paste dentifrice during a one month period. The children brushed without supervision and were examined without their knowledge. Examinations after the initial use and after a month of use of the two dentifrices showed no significant differences in toothbrushing times or patterns. Also, there were no significant deviations from the baseline scores. The study further demonstrated that uninstructed children in this age category brushed their teeth for approximately one minute per brushing, but failed to brush 38% of the tooth surfaces. The lingual surfaces were the areas most often missed, whereas the buccal, labial, and mandibular occlusal surfaces were the areas brushed most thoroughly.
本研究调查了两组儿童在一个月期间使用半透明凝胶牙膏或传统膏状牙膏时的刷牙次数和方式。这些儿童在无人监督的情况下刷牙，且在他们不知情的情况下接受检查。在初次使用两种牙膏以及使用一个月后进行的检查显示，刷牙次数或方式没有显著差异。此外，与基线分数相比也没有显著偏差。该研究进一步表明，这个年龄段未受过指导的儿童每次刷牙约一分钟，但有38%的牙面未刷到。舌面是最常被遗漏的区域，而颊面、唇面和下颌咬合面是刷牙最彻底的区域。
