The objective of this randomized, single use, single blind, single center, 4-group parallel clinical study was to evaluate the plaque removal efficacy of three power toothbrushes and a manual toothbrush.
One hundred forty-four (144) subjects completed the study. Subjects were randomly assigned to one of four toothbrush groups: Sonicare Elite, Oral-B Sonic Complete, Waterpik Sensonic or Oral-B Indicator (manual). Subjects abstained from brushing 23-25 hours prior to the pre-brushing data collection. Pre-brushing scores were obtained using the Rustogi modified navy plaque index (RMNPI). Post-brushing RMNPI scores were obtained after a supervised uninstructed two-minute brushing with the assigned toothbrush. Scores were recorded for whole mouth, marginal region, and approximal region for each subject.
Pre-brush comparability of whole mouth, marginal and approximal regions indicated no statistical differences among the four groups for any of the three measurement regions. All four toothbrushes showed statistically significant change from pre-brush to post-brush scores for whole mouth, marginal region, and approximal region. The Waterpik Sensonic provided significantly greater reduction in plaque as measured by the RMNPI compared to the other three brushes for whole mouth (89%), marginal area (81%) and approximal area (97%). The only exception was for adjusted p-values for the approximal area compared to the Oral-B Sonic Complete (p = 0.12).
All groups demonstrated a significant reduction in plaque. The single use plaque removal efficacy of the Waterpik Sensonic toothbrush compared favorably to the other two power toothbrushes, the Sonicare Elite and the Oral-B Sonic Complete, and compared favorably to the manual toothbrush, the Oral-B Indicator.
本随机、一次性使用、单盲、单中心、4组平行临床研究的目的是评估三款电动牙刷和一款手动牙刷的牙菌斑清除效果。
144名受试者完成了该研究。受试者被随机分配到四组牙刷组之一：飞利浦Sonicare Elite、欧乐-B Sonic Complete、洁碧Sensonic或欧乐-B Indicator（手动）。在刷牙前数据收集前，受试者23至25小时不刷牙。刷牙前使用Rustogi改良海军牙菌斑指数（RMNPI）获得分数。在使用指定牙刷进行无指导的两分钟监督刷牙后，获得刷牙后的RMNPI分数。记录每个受试者全口、边缘区域和邻面区域的分数。
全口、边缘和邻面区域刷牙前的可比性表明，四组在三个测量区域中的任何一个区域均无统计学差异。所有四款牙刷在全口、边缘区域和邻面区域的刷牙前分数与刷牙后分数之间均显示出统计学上的显著变化。与其他三款牙刷相比，洁碧Sensonic在全口（89%）、边缘区域（81%）和邻面区域（97%）的RMNPI测量中，牙菌斑减少幅度显著更大。唯一的例外是与欧乐-B Sonic Complete相比，邻面区域的调整p值（p = 0.12）。
所有组的牙菌斑均显著减少。洁碧Sensonic牙刷的一次性牙菌斑清除效果优于其他两款电动牙刷，即飞利浦Sonicare Elite和欧乐-B Sonic Complete，也优于手动牙刷欧乐-B Indicator。
