BACKGROUND/PURPOSE: Dental erosion in young individuals has increased significantly in recent years, due to changes in lifestyle. Thus, the present study investigated the prevalence and factors associated with dental erosion in individuals aged 12-30 years in the city of Imperatriz of Maranhão, Brazil.
A cross-sectional study was conducted on 335 individuals who answered a questionnaire consisting of variables related to dental erosion. Afterwards, the individuals were subjected to clinical examinations and the basic erosive wear examination index was used to classify their teeth according to the presence and severity of dental erosion.
Descriptive statistics, the chi-square test, Poisson univariate and multivariate regression were performed at 5% level of significance. The sample was characterized by 204 females (60.9%), the majority of whom were from 12 to 19 years of age (78.5%), among whom 28.7% presented dental erosion. Their monthly family income was from 1 to 3 minimum wages (56.4%). The variables that were significantly associated with the outcome were family income, chewing gum, and consumption of soft-drinks/juices before going to sleep (=0.03, =0.001, and =0.04, respectively). Individuals who chewed chewing gum were 2.27 times (95% CI =1.43-3.60) more likely to present dental erosion than those who did not chew gum. Individuals who ingested soft drinks or juices were 2.30 times (95% CI =1.30-4.10) more likely to present dental erosion.
The prevalence of erosion reflected the need for programs of prevention and guidance for patients about the etiological factors of the disease.
背景/目的：近年来，由于生活方式的改变，年轻个体的牙齿侵蚀现象显著增加。因此，本研究调查了巴西马拉尼昂州因佩拉特里斯市12至30岁个体牙齿侵蚀的患病率及相关因素。
对335名个体进行了一项横断面研究，这些个体回答了一份包含与牙齿侵蚀相关变量的问卷。之后，对这些个体进行临床检查，并使用基本侵蚀磨损检查指数根据牙齿侵蚀的存在情况和严重程度对他们的牙齿进行分类。
进行了描述性统计、卡方检验、泊松单变量和多变量回归分析，显著性水平为5%。样本中有204名女性（60.9%），其中大多数年龄在12至19岁之间（78.5%），其中28.7%存在牙齿侵蚀。他们的家庭月收入为1至3个最低工资（56.4%）。与结果显著相关的变量是家庭收入、嚼口香糖以及睡前饮用软饮料/果汁（分别为=0.03、=0.001和=0.04）。嚼口香糖的个体出现牙齿侵蚀的可能性是不嚼口香糖个体的2.27倍（95%置信区间=1.43 - 3.60）。摄入软饮料或果汁的个体出现牙齿侵蚀的可能性是2.30倍（95%置信区间=1.30 - 4.10）。
侵蚀的患病率反映了需要针对该疾病的病因因素为患者制定预防和指导计划。
