Population-based studies estimating the prevalence of tooth bleaching desire or the percentage of individuals who had performed this treatment are rare. Thus, the aim of this study was to evaluate the desire to perform tooth bleaching and the prevalence of adult individuals who had performed the treatment and investigate the association of these outcomes. A subsample (n = 536) of the 1982 Pelotas birth cohort in southern Brazil was investigated at the ages 15, 24 and 31 by clinical examinations and interviews. The prevalence of bleaching at 31 years was 15.6% [95%CI 12.6-18.9] while 85.9% [95%CI 82.7-88.7] reported they desired the treatment. Multivariate Poisson regression analysis showed that individuals who have visited the dentist within the last year showed a treatment prevalence ratio (PR) 2.31 times [95%CI 1.40-3.83] higher compared with those who had the last dental visit more than a year before the interview. Similarly, individuals with smoking habits presented an elevated PR of 1.60 [95%CI 1.00-2.55], and the low-income trajectory group showed the largest PR of desire for tooth bleaching (1.17 [95%CI 1.07-1.28]). Moreover, individuals from the high-risk caries trajectory group presented a higher prevalence of desire for tooth bleaching than individuals from low caries trajectory group. Individuals who have declared being "dissatisfied" with their dental color presented a prevalence of desire for tooth bleaching 16% greater than "satisfied" ones. Thus, the present findings confirm that tooth bleaching has become a frequently desired dental treatment to improve dental aesthetics in the population and a considerable rate of adults has performed the treatment.
基于人群的研究中，估计牙齿美白意愿的流行率或已接受该治疗的个体百分比的研究很少。因此，本研究的目的是评估进行牙齿美白的意愿、已接受该治疗的成年个体的流行率，并调查这些结果之间的关联。对巴西南部1982年佩洛塔斯出生队列中的一个子样本（n = 536）在15岁、24岁和31岁时进行了临床检查和访谈。31岁时牙齿美白的流行率为15.6% [95%可信区间12.6 - 18.9]，而85.9% [95%可信区间82.7 - 88.7]的人表示他们希望接受该治疗。多变量泊松回归分析显示，在过去一年中看过牙医的个体的治疗流行率比在访谈前一年多以前看过牙医的个体高2.31倍 [95%可信区间1.40 - 3.83]。同样，有吸烟习惯的个体的流行率比值升高至1.60 [95%可信区间1.00 - 2.55]，低收入轨迹组对牙齿美白的意愿流行率比值最高（1.17 [95%可信区间1.07 - 1.28]）。此外，高龋齿风险轨迹组的个体对牙齿美白的意愿流行率高于低龋齿轨迹组的个体。表示对牙齿颜色“不满意”的个体对牙齿美白的意愿流行率比“满意”的个体高16%。因此，本研究结果证实，牙齿美白已成为人们普遍希望进行的一种改善牙齿美观的牙科治疗，并且有相当比例的成年人已接受该治疗。
