The effectiveness of at-home dental bleaching treatments depends on the time that bleaching products are in contact with the teeth surface and, consequently, on the adequate use of associated custom acetate trays.
This randomized single-blinded trial aimed to analyze if the daily usage time of these products influences the patient's compliance behavior when submitted to monitored at-home dental bleaching. Secondary outcomes were color change and tooth sensitivity.
Sixty-six volunteers were randomly distributed into three groups (n=22): patients were instructed to use the trays for 2 (G2), 4 (G4), and 8 (G8) hours daily. The daily dental bleaching compliance behavior was measured using a microsensor inserted into the trays. Subjective and objective color evaluation assessments were adopted at baseline (T0), one (T1), two (T2), and three weeks (T3) after the beginning of the bleaching treatment, as well as two weeks after the treatment (T4). Tooth sensitivity was analyzed using the VAS scale, ranging from T1 to T4.
G2 showed a greater degree of cooperation than G8 and cooperation was inversely proportional to the recommended usage time. Significantly higher color change was observed in the upper arch for G8 when compared to G2 in subjective analysis, from T1 to T4. There were no statistical differences between the groups in objective analysis.
Shorter recommended usage time of the bleaching product may improve the patient's compliance with at-home dental bleaching treatments. However, increased daily usage time may promote better subjective color change. Bleaching sensitivity was more significant in the first week for a longer time of use.
家庭牙漂白治疗的效果取决于漂白产品与牙齿表面接触的时间，因此，适当使用相关的定制醋酸盐托盘非常重要。
本随机单盲试验旨在分析这些产品的每日使用时间是否会影响接受监测的家庭牙漂白治疗的患者的依从性行为。次要结果是颜色变化和牙齿敏感。
将 66 名志愿者随机分为三组（n=22）：患者被指示每天使用托盘 2（G2）、4（G4）和 8（G8）小时。使用插入托盘的微传感器测量每日牙科漂白依从性行为。在基线（T0）、第 1 天（T1）、第 2 天（T2）和第 3 周（T3）后以及治疗结束后两周（T4）进行主观和客观颜色评估。使用 VAS 量表分析牙齿敏感性，范围从 T1 到 T4。
G2 的合作程度大于 G8，合作程度与推荐使用时间成反比。在主观分析中，从 T1 到 T4，G8 的上颌牙齿颜色变化明显大于 G2。在客观分析中，各组之间没有统计学差异。
缩短漂白产品的推荐使用时间可能会提高患者对家庭牙漂白治疗的依从性。然而，增加每日使用时间可能会促进更好的主观颜色变化。使用时间较长的漂白敏感性在第一周更为明显。
