The purpose of this study was to compare the effectiveness of plaque removal of the Water Pik Automatic Toothbrush and Interplak brush versus the Oral B-40 manual brush. Thirty healthy patients having plaque on all tooth surfaces were admitted for this two-week, double-blind study. Patients served as their own control by brushing manually for one week, and then for a second week with a randomly-assigned electric brush. Three plaque indexes were scored at baseline, one week and two weeks. For all these indexes, results showed that the Water Pik Automatic Toothbrush removed significantly more plaque than manual brushing. The Interplak brush removed statistically more plaque than manual brushing only with the Turesky Index. The data for all indexes have a trend toward better plaque scores for patients who used the Water Pik Automatic Toothbrush. However, statistical analysis of these scores showed that both electric toothbrushes performed equally well.
本研究的目的是比较Water Pik自动牙刷和Interplak牙刷与Oral B - 40手动牙刷在清除牙菌斑方面的效果。30名所有牙面均有牙菌斑的健康患者被纳入这项为期两周的双盲研究。患者先手动刷牙一周作为自身对照，然后随机分配使用电动牙刷再刷一周。在基线、一周和两周时对三个牙菌斑指数进行评分。对于所有这些指数，结果显示Water Pik自动牙刷清除的牙菌斑明显多于手动刷牙。仅在Turesky指数方面，Interplak牙刷清除的牙菌斑在统计学上多于手动刷牙。对于所有指数的数据，使用Water Pik自动牙刷的患者牙菌斑评分有变好的趋势。然而，对这些评分的统计分析表明，两种电动牙刷的表现同样良好。
