This study was aimed to assess the efficacy of wet and dry brushing on cleaning outcome of tooth surfaces.
Forty-three children aged 10-12 years were randomly selected and instructed for this brushing project. Each case served as self-control. Each patient was requested to brush through one of the wet/dry techniques for 1 week and other technique on the 2 week. Samples had a washout step using pumice prophylaxis prior to each brushing week. Tooth Cleanliness Index was used to measure the plaque removal level. Two uniform Oral-B toothbrushes were used one for each week through the Modified Stillman technique. Mann-Whitney test was employed along with the Wilcoxon signed-rank test to analyze the data.
The level of brushing efficacy was slightly higher in males with no statistically significant difference between sexes. Remaining plaque measured was higher in wet group with significant difference (7.3 ± 1.7 for dry brushing and 7.6 ± 2.6 for wet brushing) (P < 0.05).
Dry and wet brushing did not show a significant difference in their capacity to remove plaque indicating that dry brushing could be considered as an acceptable brushing technique.
本研究旨在评估湿刷法和干刷法对牙齿表面清洁效果的影响。
随机选取43名10至12岁的儿童参与本次刷牙项目并给予指导。每个病例均作为自身对照。要求每位患者采用湿刷法或干刷法中的一种刷牙1周，然后在第2周采用另一种方法刷牙。在每个刷牙周之前，样本均有一个使用浮石进行预防性清洁的冲洗步骤。使用牙齿清洁指数来测量牙菌斑清除水平。通过改良Stillman刷牙法，每周使用两支统一的欧乐B牙刷。采用Mann-Whitney检验和Wilcoxon符号秩检验来分析数据。
男性的刷牙效果水平略高，性别之间无统计学显著差异。湿刷组剩余牙菌斑测量值较高，差异有统计学意义（干刷为7.3±1.7，湿刷为7.6±2.6）（P<0.05）。
干刷法和湿刷法在清除牙菌斑的能力上没有显著差异，这表明干刷法可被视为一种可接受的刷牙方法。
