目的通过随机对照临床试验，测定办公室内美白间歇期使用预先装满的家庭美白托盘进行双重美白时的美白效果、牙齿敏感度和绝对风险。用预先装满的含有6%过氧化氢的增白剂的托盘进行居家增白。66名受试者被随机分配到三组。I组：在办公室美白之间进行10次居家美白。II组：在办公室美白治疗之间进行5次居家美白。III组：仅在办公室内进行美白。用分光光度计测牙齿颜色的变化。结果所有患者的ΔE*ab、ΔE00和ΔWID均随着美白次数的增加而增加。第3次美白时，I组的ΔE*ab、ΔE00和ΔWID均显著高于III组。牙齿敏感度在美白后24 h内均高于III组。结论虽然预充托盘和办公室内美白双重美白的美白能力高于单独办公室内美白，但牙齿敏感的强度和绝对风险是相似的。
ObjectiveThis controlled randomized clinical trial determined the whitening efficacy and the intensity and absolute risk of tooth sensitivity in dual whitening when prefilled at‐home whitening trays were used between in‐office whitening intervals.Materials and MethodsAn in‐office whitening agent containing 35% hydrogen peroxide was used. A prefilled tray with a whitening agent containing 6% hydrogen peroxide was used for at‐home whitening. Sixty‐six subjects were randomly assigned to three groups. Group I: at‐home whitening was performed 10 times between the in‐office whitening treatments. Group II: at‐home whitening was performed five times between the in‐office whitening treatments. Group III: only in‐office whitening was performed. The tooth color changes were evaluated using a spectrophotometer. A visual analog scale was used to express the pain intensity.ResultsAll the groups showed increased ΔE*ab, ΔE00, and ΔWIDwith increased whitening sessions. Group I at the 3rd whitening session showed significantly higher ΔE*ab, ΔE00, and ΔWIDthan group III. Tooth sensitivity showed higher values up to 24 h after whitening.ConclusionsAlthough dual whitening with the prefilled tray and in‐office whitening had higher whitening ability than in‐office whitening alone, the intensity and absolute risk of tooth sensitivity was similar.Clinical RelevanceThe dual whitening might produce faster and stronger whitening effects than in‐office whitening alone.
