本临床试验的目的是比较在使用GLUMA脱敏剂PowerGel或安慰剂后使用过氧化氢凝胶漂白期间和之后的牙齿敏感性。纳入46名上颌门牙和犬齿健全的受试者。通过与Vitapan经典色度指南的比较确定牙齿色度。将GLUMA脱敏剂PowerGel和安慰剂随机涂抹于左、右前牙唇面1分钟，然后冲洗干燥。然后，将40%的Opalescence Boost PF凝胶涂在唇牙釉质上15分钟。敏感度评分[记录在10点视觉模拟量表（VAS）上]在漂白治疗前、5分钟、10分钟和15分钟，以及漂白治疗后1、24、48小时和1周进行测定。色度在漂白后和1周后测定。与安慰剂治疗相比，在漂白前应用GLUMA脱敏剂PowerGel可显著降低漂白期间和漂白后的牙齿敏感性。与漂白前的颜色相比，漂白后立即和1周的美白效果显著。综上所述，在用40%过氧化氢凝胶进行15分钟的牙齿漂白之前，用GLUMA脱敏剂PowerGel对牙齿进行预处理1分钟，可以有效地降低牙齿在漂白期间和之后的敏感性。
The aim of this clinical trial was to compare tooth sensitivity during and after bleaching with hydrogen peroxide gel following application of GLUMA Desensitizer PowerGel or placebo. Forty‐six subjects with sound maxillary incisors and canines were enrolled. Tooth shades were determined by comparison with a Vitapan Classic Shade guide. GLUMA Desensitizer PowerGel and placebo were randomly applied to the labial surfaces of the left or right anterior teeth for 1 min, which were then rinsed and dried. Then, Opalescence Boost PF 40% gel was applied onto labial enamel for 15 min. Sensitivity scores [recorded on a 10‐point visual‐analog scale (VAS)] were determined before, at 5, 10, and 15 min during, and 1, 24, 48 h and 1 wk after, the bleaching treatment. Shades were determined postbleaching and after 1 wk. Prebleaching application of GLUMA Desensitizer PowerGel significantly reduced tooth sensitivity during and after bleaching when compared with treatment with placebo. The whitening effects immediately and 1 wk after bleaching were significant when compared with the prebleaching shades. In conclusion, tooth pretreatment with GLUMA Desensitizer PowerGel for 1 min prior to 15 min of in‐office bleaching with 40% hydrogen peroxide gel was highly effective in reducing tooth sensitivity during and after bleaching.
