The aim of the study was to determine the whitening efficacy of three different oral rinses.
Eighty extracted teeth were randomly divided into four groups, cleaned with a slow-speed handpiece with pumice and placed in a staining broth for 14 days. Measurements of tooth shades were measured with a spectrophotometer. Three groups (20 each) were then exposed to Colgate Plax Whitening Blancheur (A), White Glo 2 in 1 (B) and Plus White (C) for 21 days for 2 minutes a day and in between stored in artificial saliva. The other group acted as a control and was only stored in the artificial saliva.
The Kruskal-Wallis and Tukey-Kramer analysis showed no statistical significant differences (on a 5% basis) for the differences between base-line and after treatment (21 days) for deltaL*, deltaa*, deltab* and deltaE*ab median values amongst the control, Colgate Plax Whitening Blancheur, White Glo 2 in 1, and Plus White.
None of the 3 commercially available oral rinses resulted in any significant bleaching effect on the teeth over a 21 day treatment period.
本研究的目的是确定三种不同口腔含漱液的美白效果。
80颗拔除的牙齿随机分为四组，用低速手机配合浮石进行清洁，然后置于染色液中14天。用分光光度计测量牙齿颜色。然后，三组（每组20颗）分别使用高露洁全效美白漱口水（A）、皓齿二合一漱口水（B）和倍加洁漱口水（C），每天使用2分钟，持续21天，期间储存在人工唾液中。另一组作为对照组，仅储存在人工唾液中。
Kruskal-Wallis和Tukey-Kramer分析显示，对照组、高露洁全效美白漱口水组、皓齿二合一漱口水组和倍加洁漱口水组之间，基线与治疗后（21天）的ΔL*、Δa*、Δb和ΔEab中位数差异无统计学意义（基于5%）。
在21天的治疗期内，三种市售口腔含漱液均未对牙齿产生任何显著的漂白效果。
