The aim of this study was to estimate the impact of malocclusion on the oral health-related quality of life (OHRQoL) of schoolchildren aged 8-12 years old in Southern Brazil. A two-stage cluster procedure was used to select 1,199 children in 20 public and private schools in Pelotas/Brazil. Cross-sectional data was collected, consisting of a socioeconomic questionnaire to parents, children's interview and clinical oral examination. The clinical variables were obtained from clinical examination, and the Child Perceptions Questionnaire (CPQ) was assessed during children's interview. To measure malocclusion and orthodontic treatment need the Dental Aesthetic Index was used. For data analysis multiple Poisson regression models estimating the rate ratios (RR) and their respective confidence intervals (95%CI) were used. Among 1,206 participants, 789 were aged 8-10 years and 417 between 11-12 years. The orthodontic treatment need was higher among the younger children (44.6%) than in the older ones (35.0%) (p value ≤0.05). There was a significant association in the CPQ social and emotional domains with malocclusion in the older schoolchildren. In the adjusted analysis (for socioeconomics and clinical variables) the effect of very severe malocclusion on OHRQoL was confirmed in both 8-10 and 11-12 age groups (RR(95%CI) of 1.24(1.02;1.51) and 1.28(1.01;1.62), respectively). The findings demonstrated that children with very severe malocclusion experienced greater negative impact on OHRQoL compared to those with mild or no malocclusion. The results suggest that malocclusion impacts the quality of life. The higher impact occurs in the social and emotional well-being domains.
本研究的目的是评估错牙合畸形对巴西南部8至12岁学童口腔健康相关生活质量（OHRQoL）的影响。采用两阶段整群抽样程序，从巴西佩洛塔斯的20所公立和私立学校中选取了1199名儿童。收集了横断面数据，包括给家长的社会经济调查问卷、儿童访谈和临床口腔检查。临床变量通过临床检查获得，儿童访谈期间评估儿童感知问卷（CPQ）。使用牙科美学指数来测量错牙合畸形和正畸治疗需求。数据分析采用多重泊松回归模型，估计率比（RR）及其各自的置信区间（95%CI）。在1206名参与者中，789名年龄在8至10岁之间，417名年龄在11至12岁之间。正畸治疗需求在年幼儿童中（44.6%）高于年长儿童（35.0%）（p值≤0.05）。年长学童的CPQ社会和情感领域与错牙合畸形之间存在显著关联。在调整分析（针对社会经济和临床变量）中，8至10岁和11至12岁年龄组中，非常严重的错牙合畸形对OHRQoL的影响均得到证实（RR(95%CI)分别为1.24(1.02;1.51)和1.28(1.01;1.62)）。研究结果表明，与轻度或无错牙合畸形的儿童相比，非常严重的错牙合畸形儿童在OHRQoL方面受到的负面影响更大。结果表明，错牙合畸形会影响生活质量。在社会和情感幸福领域的影响更大。
