摘要
目的 对平切型和波浪型牙刷的刷牙效果作一比较。方法 将实验对象分成两组 ,分别使用平切型和波浪型牙刷 ,刷牙前后分别各做一次菌斑检查。结果 统计分析结果显示使用波浪型牙刷清除菌斑效果较平切型牙刷略为有效 ,相差率为 5 .2 6 % ,主要表现在牙齿的唇颊面 (P <0 .0 1)和近中牙面的 (P<0 .0 1)清洁效果相差显著 ,而在牙齿的远中牙面和舌腭牙面的清洁效果两者没有明显差异 (P <0 .0 5 )。结论 波浪型牙刷与平切型牙刷相比较更易清除唇颊面和近中牙面菌斑。
Aim This cilinical studies were performed to compare two toothbrushes for their ability to remove dental plaque. Methods Subjects were randomly assignd to one of two groups. The flat bristled toothbrushe was compared to the wave bristled tootbrushe. Subjects were screened for dental plaque on the all natural teeth except thirdmolar, using the O'Leary plaque record after and before toothbrushing. Results The wave bristled toothbrushe was significantly more effective (P<0.01) than the flat bristled toothbrushe to remove plaque on the facial and near centrol line dental surfaces of all natural teeth, difference rate wes 5. 26 percent. Conclusions The wave bristled toothbrushe removed significantly more plaque than the flat bristled toothbrushe,dental plaque remove efficiency difference were significant when the facial and near centrol line dantal surfaces was evaluated.
