: To identify adolescents' self-perception of dental fluorosis from two areas with different socioeconomic levels. : A cross-sectional, descriptive study was conducted with 15-year-old youths by applying a questionnaire designed and validated to assess self-perceptions of dental fluorosis in two areas with different socioeconomic statuses (SESs). Fluorosis was clinically evaluated by applying the Thylstrup and Fejerkov (TF) index on the upper front teeth. : A total of 308 adolescents were included in the study. The medium-SES population, which was exposed to 2.5 ppm of fluoride in water, and the low-SES population, which was exposed to 5.1 ppm, presented the following levels of dental fluorosis: TF 2-3 (50%), TF 4-5 (45.6%) and TF 6-7 (4.4%) for medium SES and TF 2-3 (12.3%), TF 4-5 (67.1%) and TF 67 (20.6%) for low SES. A significant association was found between self-perception and dental fluorosis in those with medium and low SESs ( < 0.05). The multiple regression model found differences between TF levels and self-perception, with a 6-7 TF level for concerns about color (OR = 1.6), smile (OR = 1.2) and appearance (OR = 3.36). : Self-perceptions of dental fluorosis affect adolescents such that adolescents with a medium SES have more negative perceptions than those with a low SES. Such perceptions increase as the TF index increases.
识别来自两个社会经济水平不同地区的青少年对氟斑牙的自我认知情况。
采用横断面描述性研究方法，对15岁青少年进行调查，应用经过设计和验证的问卷来评估两个社会经济地位（SES）不同地区青少年对氟斑牙的自我认知。通过对上前牙应用蒂尔斯楚普和费耶尔科夫（TF）指数对氟斑牙进行临床评估。
该研究共纳入308名青少年。中等SES人群（水中氟暴露量为2.5 ppm）和低SES人群（水中氟暴露量为5.1 ppm）的氟斑牙水平如下：中等SES人群中，TF 2 - 3级（50%）、TF 4 - 5级（45.6%）和TF 6 - 7级（4.4%）；低SES人群中，TF 2 - 3级（12.3%）、TF 4 - 5级（67.1%）和TF 6 - 7级（20.6%）。在中等和低SES人群中，自我认知与氟斑牙之间存在显著关联（<0.05）。多元回归模型发现TF水平与自我认知之间存在差异，TF 6 - 7级者在牙齿颜色（OR = 1.6）、笑容（OR = 1.2）和外观（OR = 3.36）方面的担忧更为明显。
青少年对氟斑牙的自我认知会对其产生影响，中等SES的青少年比低SES的青少年有更负面的认知。随着TF指数增加，这种认知也会增强。
