In-office teeth bleaching is an esthetic dental procedure performed to whiten teeth. A desensitizing procedure often requires prior in-office bleaching to relieve tooth hypersensitivity. The objective of this study was to evaluate the bleaching efficiency of teeth specimens pre-treated with different desensitizing agents by analyzing the color parameters. A total of 25 bovine specimens were stained and divided into five groups ( = 5). The specimens were pre-treated with GLUMA, ICON, bonding, or fluoride varnish according to the manufacturer's instructions. Subsequently, the samples underwent three consecutive 20 min bleaching sessions using an in-office bleaching product. Color values in the CIE L*, a*, and b* color space were initially recorded, both before any treatment and after each bleaching session. The color difference (ΔE) was then computed. The data were analyzed using SPSS 24.0 software. The color alteration after pre-treatment was analyzed using a one-way ANOVA test, and the color alteration in each bleaching session was compared using a repeated-measure ANOVA test. A one-way ANOVA analysis showed a statistically significant difference in the bleaching efficiency of teeth specimens pre-treated with different desensitizers ( < 0.001). The repeated-measure ANOVA analysis showed no statistically significant difference in additional bleaching sessions ( = 0.133). The ICON and bonding pre-treatment showed the color alteration of teeth specimens before the bleaching procedure. Although the different desensitizer pre-treatments showed significant differences in bleaching efficiency, the differences in color parameters of the teeth specimens at the end of three bleaching sessions were statistically insignificant. Desensitizer pre-treatment influenced the degree of color change during multiple bleaching sessions; however, the outcome of bleaching was not affected by desensitizer pre-treatment.
诊室牙齿美白是一种用于美白牙齿的美容牙科程序。脱敏程序通常需要先进行诊室美白以缓解牙齿过敏。本研究的目的是通过分析颜色参数来评估用不同脱敏剂预处理的牙齿标本的美白效率。总共25个牛牙标本被染色并分为五组（每组n = 5）。根据制造商的说明，用GLUMA、ICON、粘结剂或氟化物 varnish对标本进行预处理。随后，使用一种诊室美白产品对样本进行连续三次每次20分钟的美白疗程。在任何治疗前以及每次美白疗程后，最初记录CIE L*、a和b颜色空间中的颜色值。然后计算颜色差异（ΔE）。使用SPSS 24.0软件分析数据。使用单因素方差分析测试分析预处理后的颜色变化，使用重复测量方差分析测试比较每个美白疗程中的颜色变化。单因素方差分析显示，用不同脱敏剂预处理的牙齿标本的美白效率存在统计学上的显著差异（P < 0.001）。重复测量方差分析显示，额外的美白疗程没有统计学上的显著差异（P = 0.133）。ICON和粘结剂预处理显示了牙齿标本在美白程序前的颜色变化。尽管不同的脱敏剂预处理在美白效率上显示出显著差异，但在三次美白疗程结束时牙齿标本的颜色参数差异在统计学上并不显著。脱敏剂预处理影响了多次美白疗程中的颜色变化程度；然而，美白结果不受脱敏剂预处理的影响。
