摘要

比较使用 35% 过氧化氢(HP)或 37% 过氧化卡巴酰胺(CP)进行诊室牙齿漂白的牙齿敏感性(TS)和漂白效果(BE):35% HP 或 37% CP。使用 VAS 和 NRS 量表记录漂白后即刻、1 小时、24 小时和 48 小时内的 TS。在漂白前和漂白后 1 个月,使用色导单位(ΔSGUs)和分光光度计(ΔEab、ΔE00 和 ΔWID)对 BE 进行评估。TS 采用 McNemar 检验和配对 t 检验(VAS)或 Wilcoxon 符号秩(NRS)进行评估。采用配对 t 检验分析 BE(α = 0.05)。结果 37% CP 的 TS 风险和强度较低(p = 0.003 和 p <0.005)。尽管 1 个月后两组之间存在明显差异(ΔSGU 和 ΔE00;p < 0.05),但两组的颜色测量值都超过了 50%:50%的可感知性/可接受性阈值:试验注册:ClinicalTrials.gov identifier:RBR-683qhf

In‐Office Dental Bleaching Using 37% Carbamide Peroxide Versus 35% Hydrogen Peroxide: A Randomized, Double‐Blind Clinical Trial
ObjectiveCompare the tooth sensitivity (TS) and bleaching efficacy (BE) of in‐office dental bleaching performed with 35% hydrogen peroxide (HP) or 37% carbamide peroxide (CP).Materials and MethodsSixty‐six participants were randomly divided into two groups according to the bleaching gel applied to the right hemiarch: 35% HP, or 37% CP. TS was recorded immediately after, up to 1, 24, and 48 h after bleaching, using the VAS and NRS scales. BE was assessed before bleaching and 1 month after using color guide units (ΔSGUs) and a spectrophotometer (ΔEab, ΔE00, and ΔWID). TS was assessed using McNemar's and paired t‐test (VAS) or Wilcoxon signed rank (NRS). The paired t‐test was used to analyze BE (α = 0.05).ResultsTS risk and intensity were lower for the 37% CP (p = 0.003 and p < 0.005). Despite significant differences between the groups after 1 month (ΔSGU and ΔE00; p < 0.05), the color measurements of both groups exceeded the 50%:50% perceptibility/acceptability threshold.ConclusionIn‐office dental bleaching using 37% CP resulted in reduced risk and TS intensity, without prejudice to the BE.Clinical RelevanceThe use of 37% CP for in‐office dental bleaching could decrease TS risk and intensity without affecting BE.Trial Registration: ClinicalTrials.gov identifier: RBR‐683qhf
