Malocclusion is public health problem because of its high prevalence, treatment possibility, and impact on the individual's quality of life. This article aims to determining the prevalence of malocclusion in adolescents and to test its association with social vulnerability. A representative transversal study was performed with 1612 adolescents aged between 11 and 14 years old who came from public and private schools in Belo Horizonte, Brazil. The adolescents were examined by three calibrated examiners for diagnosis of malocclusion, using the Dental Aesthetic Index. The Social Vulnerability Index from Belo Horizonte was used to determine the degree of social vulnerability from adolescents. The data were analyzed using Poisson regression with robust variance (p<0,05). Most adolescents presented absence/minor malocclusion (68.7%). Dental crowding was diagnosed in 51.9% from the sample, diastema in 23.7%, anterior open bite in 7.6 %. Malocclusion was associated with social vulnerability (PR=1.25;95% CI=1.01-1.55). Dental crowding was the most prevalent type of malocclusion. The more socially vulnerable adolescents had worse indicators of malocclusion.
错牙合畸形是一个公共卫生问题，因其患病率高、可治疗性以及对个人生活质量的影响。本文旨在确定青少年错牙合畸形的患病率，并测试其与社会脆弱性之间的关联。对来自巴西贝洛奥里藏特公立和私立学校的1612名11至14岁青少年进行了一项具有代表性的横断面研究。由三名经过校准的检查人员使用牙科美学指数对青少年进行错牙合畸形诊断检查。使用贝洛奥里藏特的社会脆弱性指数来确定青少年的社会脆弱程度。数据采用稳健方差的泊松回归进行分析（p<0.05）。大多数青少年表现为无/轻度错牙合畸形（68.7%）。样本中51.9%被诊断为牙列拥挤，23.7%为牙间隙，7.6%为前牙开牙合。错牙合畸形与社会脆弱性相关（PR=1.25；95%CI=1.01-1.55）。牙列拥挤是最常见的错牙合畸形类型。社会脆弱性越高的青少年错牙合畸形指标越差。
