To evaluate the effects of activated charcoal-based products used in two presentation forms (powder or toothpaste), compared to 10 % carbamide peroxide and conventional toothpaste on aesthetic perception and psychosocial impact before and after treatment.
Fifty-six participants were divided into 4 experimental groups (n = 14). Activated charcoal-based powder (PW); Activated charcoal-based dentifrice (AC); Conventional fluoride toothpaste (CD) and 10 % carbamide peroxide (CP). All products were used for 14 days. Psychosocial impact on dental esthetics (PIDAQ), oral health impact profile (OHIP- Esthetics) and orofacial esthetics scale (OES) questionnaires were applied before and after treatment. Descriptive and exploratory data analyses were performed and analyzed using linear mixed models for repeated measures over time considering significance level of α = 0.05.
For PIDAQ, the CP group showed significant decrease in psychological impact, aesthetic perception domains and overall score, while in the PW group, there was only a significant decrease in the psychological impact domain. Decrease in OHIP was observed for the functional limitation domain scores for treatments with CP and PW, in the psychological discomfort domain, decrease was observed for all groups, while for the OES questionnaire, significant increase in the color domain was observed for the CP group.
Activated charcoal-based products showed lower scores in all questionnaires when compared with carbamide peroxide; thus, charcoal-based products promoted lower impact on quality of life and aesthetic perception.
In this randomized clinical trial, charcoal-based OTC products had inferior quality of life and aesthetic perception results compared to conventional carbamide peroxide bleaching.
评估两种剂型（粉末或牙膏）的活性炭制品与 10%过氧化脲和普通牙膏在治疗前后对美观感知和心理社会影响的效果。
将 56 名参与者分为 4 个实验组（n=14）。活性炭粉（PW）；活性炭牙膏（AC）；含氟普通牙膏（CD）和 10%过氧化脲（CP）。所有产品均使用 14 天。在治疗前后应用口腔美学影响量表（PIDAQ）、口腔健康影响量表（OHIP-美观）和口腔美学量表（OES）问卷评估心理社会影响。采用线性混合模型进行描述性和探索性数据分析，考虑到 α=0.05 的显著性水平，对时间进行重复测量。
对于 PIDAQ，CP 组在心理影响、美观感知领域和总分方面均显示出显著下降，而 PW 组仅在心理影响领域出现显著下降。CP 和 PW 治疗组的功能障碍领域评分的 OHIP 下降，所有组的心理不适领域评分下降，而 OES 问卷的颜色领域评分显著增加 CP 组。
与过氧化脲相比，基于活性炭的产品在所有问卷中的得分较低；因此，基于活性炭的产品对生活质量和美观感知的影响较低。
在这项随机临床试验中，与传统的过氧化脲漂白相比，非处方的基于活性炭的产品对生活质量和美观感知的结果较差。
