本研究比较了活髓牙漂白技术的临床效果。在IRB批准和知情同意后，根据前牙的色度（A2或更深，Vita Classic色度指南）选择90名受试者。在分口研究设计中，受试者被分配到三个治疗组：第1组：HB（使用10%过氧化脲在家漂白两周）与OBL（使用35%过氧化氢在诊所漂白，两个疗程，间隔两周，光照射）;第II组：OB（不使用光照射的诊所漂白）与OBL;第III组：HB与联合治疗（一个疗程加HB）。测量16周的颜色变化和颜色反弹（Δ E）。在基线、1、2、4、8和16周时，使用分光光度计和比色板进行颜色测量。使用VAS量表评价牙齿敏感性15天。采用Student t检验和Tukey-Kramer检验对结果进行分析（p
This study compared the clinical outcome of bleaching techniques in vital teeth. After IRB approval and informed consent, 90 subjects were selected based on the shade of their anterior teeth (A2 or darker, Vita Classic shade guide). Subjects were assigned to three treatment groups in a split-mouth study design: Group 1: HB (at-home bleaching with 10% carbamide peroxide for two weeks) vs OBL (in-office bleaching with 35% hydrogen peroxide, two sessions, two-week intervals, with light irradiation); Group II: OB (in-office bleaching without light irradiation) vs OBL; Group III: HB vs combination (one session plus HB). Color change and color rebound (Delta E) were measured for a 16-week period. Color measurements were carried out with both a spectrophotometer and a shade guide at baseline, 1, 2, 4, 8 and 16 weeks. Tooth sensitivity was evaluated using a VAS scale for 15 days. Both the Student's t-test and Tukey-Kramer test were used to analyze the results (p
