This study evaluated the variation of surface and intra-pulpal temperature, during bleaching protocol, using LED/laser. The 35% (HP35), 15% (HP15) and 6% (HP6) gels were used associated with LED/laser applied every 1 min for 30 min in a human canine. The evaluation of surface temperature variation (∆Ts) was performed using a pHmeter and the intra-pulpal temperature variation (∆Ti) was performed using a digital thermometer, at times of 1-, 5-, 10- 15- and 30-min. Statistical analysis was performed using the two-way repeated measures ANOVA test and Bonferroni post-hoc test was used at a significance level of 5%. HP35 and HP15 showed greater temperature variation than HP6 up to 10 min of surface evaluation, showing no differences between them. In the intra-pulpal evaluation, no group showed differences throughout the procedure.
本研究评估了在使用发光二极管/激光进行漂白方案期间，牙齿表面和牙髓内温度的变化。在一颗人犬齿上，使用35%（HP35）、15%（HP15）和6%（HP6）的凝胶，并每隔1分钟应用发光二极管/激光30分钟。在1分钟、5分钟、10分钟、15分钟和30分钟时，使用pH计评估表面温度变化（∆Ts），并使用数字温度计评估牙髓内温度变化（∆Ti）。采用双向重复测量方差分析进行统计分析，并使用Bonferroni事后检验，显著性水平为5%。在表面评估的前10分钟内，HP35和HP15的温度变化比HP6更大，它们之间没有差异。在牙髓内评估中，整个过程中各组均无差异。
