摘要

目的:尽管有6%过氧化氢浓度的办公室漂白凝胶,但这些凝胶尚未在年轻患者中进行评估。它们在市场上有一个尖端,与刷子相连或不与刷子相连,其中带有刷子的尖端将凝胶分散在整个表面上,以具有较小的厚度(薄层),因为制造商指示应用薄层凝胶。这项随机、分口、双盲的临床试验评估了使用不同涂抹技巧的青少年使用6%HP的办公室漂白的疗效,以及牙齿敏感性(TS)和审美自我感知。方法:60名参与者被随机分配为6%HP自混合漂白凝胶尖端设计:无刷和有刷。办公室漂白在50分钟的3个疗程中进行。使用数字分光光度计(ΔE ab、ΔE 00和ΔWI D)和颜色指南(ΔSGU)评估颜色变化,用视觉模拟量表评估TS的绝对风险和强度,用口腔美学量表评估美学自我感知(a=0.05),在第三周(MD 2.3;95%CI 1.2至3.3;p<0.001)和一个月(MD 1.6;95%CI 0.6至2.6;p<0.03)观察到显著的平均差异(MD),有利于无刷的尖端。关于TS,无刷组45%的患者和有刷组33%的患者报告TS(比值比0.61;95%可信区间0.29-1.28;p0.36)(MD-1.3;95%-1.8-0.9;P结论:无论使用何种尖端,使用6%HP漂白都能达到漂白效果,并改善美感。然而,使用带刷的尖端应用TS的风险较低。

In-office dental bleaching in adolescents using 6% hydrogen peroxide with different application tips: randomized clinical trial.

In-office dental bleaching in adolescents using 6% hydrogen peroxide with different application tips: randomized clinical trial.

In-office dental bleaching in adolescents using 6% hydrogen peroxide with different application tips: randomized clinical trial.

Objective: Despite the availability of in-office bleaching gels with a 6% concentration of hydrogen peroxide (HP), these gels have not been evaluated in younger patients. They are commercially available with a tip, associated or not with a brush, where the tip with a brush spreads the gel over the entire surface to have a smaller thickness (thin layer) since the manufacturers indicate the application of a thin layer of gel. This randomized, split-mouth, double-blind clinical trial evaluated the efficacy of in-office bleaching with 6% HP in adolescents using different application tips, as well tooth sensitivity (TS) and aesthetic self-perception.

Methodology: Sixty participants were randomized for 6% HP self-mixing bleaching gel tip design: without brush and with brush. In-office bleaching was performed in 3 sessions of 50 minutes. Color change was evaluated using a digital spectrophotometer (ΔE ab , ΔE 00 , and ΔWI D ) and color guide (ΔSGU), the absolute risk and intensity of TS with a visual analogue scale and aesthetic self-perception with the oral aesthetic scale (a=0.05).

Results: The groups achieved similar bleaching regardless of the application tip (p>0.05). However, only for ΔWI D , a significant mean difference (MD) was observed in the third week (MD 2.3; 95% CI 1.2 to 3.3; p < 0.001) and at one month (MD 1.6; 95% CI 0.6 to 2.6; p < 0.03) favoring the tip without brush. Regarding TS, 45% in the tip-without-brush group and 33% in the tip-with-brush group reported TS (odds ratio 0.61; 95% CI 0.29 to 1.28; p<0.02), with low TS intensity (MD 0.05; 95% CI -0.06 to 0.17; p>0.36). All patients reported improved aesthetic self-perception after bleaching (MD -1.3; 95% -1.8 to -0.9; p<0.001).

Conclusions: Regardless of the tip used bleaching with 6% HP achieved a bleaching efficacy and improved the aesthetic self-perception. However, a lower risk of TS for application using the tip with brush was observed.
