摘要
目的：评估使用不同涂抹技巧的诊所漂白效果（BE）和牙齿敏感性（TS）：评估使用不同刷头进行诊室漂白的漂白效果（BE）和牙齿敏感性（TS）：选取 48 名参与者（分口），其中一名接受附着式刷头漂白，另一名接受传统刷头漂白。漂白过程使用 35% 的 Whiteness Automixx Plus。使用 Vita Easyshade 分光光度计（ΔE*ab、ΔE00 和 WID）以及 Vita classic A1-D4 和 Vita Bleachedguide 色度指南（ΔSGU），在漂白开始时、每周、漂白后 1 个月和 12 个月对 BE 进行评估。使用视觉模拟量表记录 TS 的绝对风险和强度。采用配对样本的两个单侧 t 检验分析 BE 的等效性。TS 绝对风险采用 McNemar 检验，TS 强度采用配对 t 检验（α = 0.05）：结果：在所有颜色评估中，两组患者的 BE 值相等（P > 0.05）。与传统刷头相比，附着刷头的 TS 绝对风险和强度较低（p 结论：附着刷头与传统刷头的 TS 绝对风险和强度相同：附着式刷头与传统刷头的 BE 值相同。然而，附着式刷头的 TS 有所降低：临床意义：由于附着式刷头可降低 TS 的风险和强度，建议在诊室内进行牙齿漂白。
Effect of the type of application tip for 35% hydrogen peroxide on bleaching efficacy and tooth sensitivity: A randomized clinical trial
Objectives
Evaluate the bleaching efficacy (BE) and tooth sensitivity (TS) of in-office bleaching using different application tips.
Methods
Forty-eight participants were selected (split-mouth), one to receive bleaching with an attached brush tip and one with a conventional tip. The procedure was performed with Whiteness Automixx Plus 35%. The BE was evaluated at the beginning, weekly, one and 12 months post-bleaching with a Vita Easyshade spectrophotometer (ΔE*ab, ΔE00, and WID) and with Vita classical A1-D4 and Vita Bleachedguide shade guides units (ΔSGU). Absolute risk and intensity of TS were recorded using the Visual Analogue Scale. The equivalence of BE was analyzed using the two one-sided t-tests for paired samples. The absolute risk of TS was evaluated using the McNemar test, and the TS intensity was measured with the paired t test (α = 0.05).
Results
The equivalence of BE was observed for both groups in all color evaluations (p > 0.05). A lower absolute risk and intensity of TS were observed for the attached brush tip when compared with the conventional tip (p < 0.003 and p < 0.0001).
Conclusion
Using an attached brush tip showed the same BE as a conventional tip. However, for the attached brush tip, there was a reduction in TS.
Clinical Significance
The applicator-attached brush tip is recommended for in-office dental bleaching, because of the possible reduction in risk and intensity of TS.
