Abstract

OBJECTIVES

To assess the influence of patient age on tooth sensitivity, bleaching effectiveness, and the self-perception and psychosocial impact of dental esthetics following in-office tooth bleaching with 35% hydrogen peroxide.

METHODS

This parallel study categorized 56 subjects by age into early adulthood (18-25 years) and middle-aged (40-65 years) groups. The bleaching agent was applied in a single 45-minute session, spanning two bleaching sessions at a 1-week interval. Bleaching effectiveness assessment used upper incisors and canines. A shade guide (VITA Bleachedguide 3D-MASTER) and a portable spectrophotometer evaluated color changes. A visual analog scale and verbal rating scale recorded tooth sensitivity during and up to 48 hours after the bleaching procedure. The Psychosocial Impact of Dental Aesthetics Questionnaire measured the self-perception and psychosocial impact of the bleaching protocol. Student t-test, Fisher exact test, Mann-Whitney, multivariate analysis of variance, chi-square, two-way repeated measures analysis of variance, and the Wilcoxon test (α=0.05) verified the data.

RESULTS

Early adulthood subjects demonstrated a significant increase (17%) in the risk of tooth sensitivity (p=0.038), and the highest pain levels occurred 1 hour after the bleaching session (p<0.01). Nonetheless, early adulthood subjects showed improved bleaching effects 30 days after the procedure when compared to the middle-aged subjects, even though the overall perception of the psychosocial impact of dental esthetics was more evident in middle-aged subjects.

CONCLUSIONS

Patient age influenced in-office bleaching outcomes. Both age groups reported esthetic satisfaction, but early adulthood subjects (18-25 years) experienced a more substantial whitening effect, greater dentin sensitivity, and higher psychological impact. Conversely, middle-aged subjects (40-65 years) had a better overall perception of the psychosocial impact of dental esthetics.

摘要

目的

评估患者年龄对牙齿敏感度、漂白效果以及使用35%过氧化氢进行诊室牙齿漂白后牙齿美学的自我认知和心理社会影响的影响。

方法

这项平行研究按年龄将56名受试者分为青年组（18 - 25岁）和中年组（40 - 65岁）。漂白剂在一次45分钟的疗程中应用，分两次漂白，间隔1周。使用上中切牙和尖牙评估漂白效果。使用比色板（VITA Bleachedguide 3D - MASTER）和便携式分光光度计评估颜色变化。使用视觉模拟量表和言语评定量表记录漂白过程中及漂白后48小时内的牙齿敏感度。使用《牙科美学心理社会影响问卷》测量漂白方案的自我认知和心理社会影响。采用学生t检验、Fisher精确检验、Mann - Whitney检验、多因素方差分析、卡方检验、双向重复测量方差分析和Wilcoxon检验（α = 0.05）对数据进行验证。
