The purpose of this randomized, single-use, single-blind, two-group, parallel pilot study was to compare the plaque removal ability of a water flosser and interdental brush when used in combination with a manual toothbrush.
Twenty-eight (28) subjects completed the study. Subjects were randomly assigned to one of two groups: Waterpik®Water Flosser (WF) plus manual tooth brushing or interdental brushes (IDB) plus manual tooth brushing. Pre-cleaning plaque scores were obtained using the Rustogi Modification of the Navy Plaque Index (RMNPI). Subjects were instructed on the use of their interdental product. Post-cleaning scores were obtained after a supervised brushing and use of the interdental device. Scores were recorded for whole mouth, marginal, approximal, facial, and lingual regions for each subject.
There were no differences between the groups for pre-cleaning plaque scores for whole mouth, marginal, approximal, facial, or lingual regions. Both groups showed significant reductions in plaque from baseline for all areas measured (p < 0.001). The WF group was significantly more effective than the IDB group for removing plaque from all areas measured. Specifically, the WF was 18% more effective for whole mouth and marginal areas, 20% for approximal areas, 11% for facial areas, and 29% for lingual areas.
The Waterpik Water Flosser and manual toothbrush removes significantly more plaque from tooth surfaces (whole mouth, marginal, approximal, facial, and lingual) than interdental brushes and a manual toothbrush after a single use.
本随机、一次性使用、单盲、两组平行的试点研究旨在比较水牙线和牙间隙刷与手动牙刷联合使用时的牙菌斑清除能力。
28名受试者完成了该研究。受试者被随机分配到两组中的一组：Waterpik®水牙线（WF）加手动刷牙或牙间隙刷（IDB）加手动刷牙。使用海军牙菌斑指数的Rustogi改良版（RMNPI）获得清洁前的牙菌斑评分。指导受试者使用牙间隙清洁产品。在监督刷牙和使用牙间隙清洁装置后获得清洁后的评分。记录每个受试者全口、边缘、邻面、颊面和舌面区域的评分。
两组在全口、边缘、邻面、颊面或舌面区域的清洁前牙菌斑评分无差异。两组在所有测量区域的牙菌斑均较基线有显著减少（p < 0.001）。在所有测量区域，WF组清除牙菌斑的效果明显优于IDB组。具体而言，WF在全口和边缘区域的效果高18%，邻面区域高20%，颊面区域高11%，舌面区域高29%。
一次性使用后，Waterpik水牙线和手动牙刷比牙间隙刷和手动牙刷能显著清除更多牙齿表面（全口、边缘、邻面、颊面和舌面）的牙菌斑。
