To evaluate the effect of malocclusion among adolescents on their families' oral health-related quality of life (OHRQoL).
A consecutive sample of 125 parents/caregivers of Brazilian adolescents was chosen. Participants were asked to answer the Brazilian version of the Family Impact Scale (FIS). The main independent variable was adolescents' malocclusion, which was measured with the Dental Aesthetic Index. Gender, age, and family monthly income were the other independent variables. Data analysis involved descriptive statistics, Mann-Whitney test, and univariate and multiple logistic regression.
Among the 125 participants initially admitted to the present study, two were excluded so that 123 parents/caregivers participated providing a response rate of 98.4 %. The overall FIS score revealed a more frequent effect for families of adolescents who presented malocclusion (P = 0.005). Significant findings were also observed for parental emotions (P = 0.022), family conflict (P = 0.010), and financial burden (P = 0.010) subscales. When the independent variables family monthly income and malocclusion were inserted together in the regression model, families with a monthly income of <5 Brazilian minimum wages (approximately US$ 325.00 per month) were more likely to have a worse OHRQoL, and families whose adolescents presented malocclusion were 3.55 more likely to have a poorer quality of life than those families whose adolescents did not present malocclusion.
Families of adolescents with malocclusion were more likely to report a worse OHRQoL.
评估青少年错牙合畸形对其家庭口腔健康相关生活质量（OHRQoL）的影响。
选取125名巴西青少年的父母/照顾者作为连续样本。参与者被要求回答巴西版的家庭影响量表（FIS）。主要自变量是青少年的错牙合畸形，用牙科美学指数进行测量。性别、年龄和家庭月收入是其他自变量。数据分析包括描述性统计、曼-惠特尼检验以及单变量和多变量逻辑回归。
在最初纳入本研究的125名参与者中，两名被排除，因此123名父母/照顾者参与，回复率为98.4%。总体FIS评分显示，有错牙合畸形的青少年家庭受到的影响更频繁（P = 0.005）。在父母情绪（P = 0.022）、家庭冲突（P = 0.010）和经济负担（P = 0.010）子量表上也观察到显著结果。当将家庭月收入和错牙合畸形这两个自变量一起纳入回归模型时，月收入低于5个巴西最低工资（约合每月325.00美元）的家庭更有可能有较差的OHRQoL，青少年有错牙合畸形的家庭比青少年无错牙合畸形的家庭生活质量差的可能性高3.55倍。
有错牙合畸形的青少年家庭更有可能报告较差的OHRQoL。
