摘要

目的:合成含四种不同聚合物(线性聚磷酸钠[LPP];壳聚糖(气);六偏磷酸钠;和焦磷酸钠[PP]),并测试其预防和去除牙齿外源性染色的能力。方法:将牙齿标本随机分为6组(n = 10):对照组(人工唾液)、普通牙膏(RT-no美白声明)、ET 5% LPP、ET 0.5% CHI、ET 5% HMP和ET 5% PP。每个周期包括氯己定(2 min)、染色汤(30 min)、人工唾液(30 min)、刷牙(45次)和人工唾液(30 min)。在基线和21个周期后评估颜色参数(L*, a*和b*)。ΔEab、ΔE00、ΔWID、ΔL、Δa、Δb采用方差分析和Tukey检验,显著性水平为5%。结果:ET 5% PP低于对照组ΔEab和ΔE00, RT (p p, PP)高于对照组。对于ΔL (p = 0.265)和Δb (p = 0.119),组间差异无统计学意义。对于Δa (p = 0.01), ET 5% PP与对照组有差异。结论:ETs在预防和清除牙齿外源性污渍方面具有相似的效果。然而,含焦磷酸钠的牙膏是唯一一种与RT或不使用牙膏相比效果更好的牙膏。临床意义:使用牙膏治疗牙齿外源性色斑是牙科常用的方法。除了磨料外,它们的效果可以通过一些聚合物的存在进一步增强。含有焦磷酸钠的牙膏显示出控制牙齿外来污渍的优越能力。

Polymer-Based Toothpastes and Their Ability in Control Tooth Extrinsic Stain.

Objectives: To synthesize experimental toothpastes (ETs) containing four different polymers (sodium linear polyphosphate [LPP]; chitosan [CHI]; sodium hexametaphosphate [HMP]; and sodium pyrophosphate [PP]) and test their ability in preventing and removing tooth extrinsic stain.

Methods: The tooth specimens were randomly assigned into six groups (n = 10): control (artificial saliva), regular toothpaste (RT-no whitening claim), ET 5% LPP, ET 0.5% CHI, ET 5% HMP, and ET 5% PP. Each cycle consisted of chlorhexidine (2 min), staining broth (30 min), artificial saliva (30 min), brushing (45 strokes), and artificial saliva (30 min). Color parameters (L*, a*, and b*) were assessed at baseline and after 21 cycles. ΔEab, ΔE00, ΔWID, ΔL, Δa, and Δb were analyzed through ANOVA and Tukey test, at a 5% significance level.

Results: ET 5% PP showed lower ΔEab and ΔE00 than the control and RT (p < 0.01). For ΔWID, PP showed a higher value. For ΔL (p = 0.265) and Δb (p = 0.119), there were no significant differences among the groups. For Δa (p = 0.01), ET 5% PP showed a difference with the control.

Conclusions: The ETs showed a similar effect in preventing and removing tooth extrinsic stains. However, the sodium pyrophosphate-containing toothpaste was the only one with a superior effect in comparison with RT or brushing without toothpaste.

Clinical significance: The use of toothpastes for managing tooth extrinsic stains is a common approach in dentistry. In addition to the abrasives, their effect can be further enhanced by the presence of some polymers. Toothpastes containing sodium pyrophosphate demonstrated a superior ability to control tooth extrinsic stains.
