Oral health-related quality of life (OHRQoL) is affected by different clinical conditions. The aim of this study was to evaluate the impact of gingivitis on OHRQoL in adolescents.
This cohort study consisted of a random sample of 1,134 schoolchildren enrolled during 2012, in Santa Maria, Brazil. After two years, 743 adolescents were follow-up (response rate: 65.5%). Clinical, socioeconomic and OHRQoL data were collected. OHRQoL was assessed by the short Brazilian version of the Child Perceptions Questionnaire 11-14 (CPQ11-14), and gingival bleeding through Community Periodontal Index. Gingivitis was considered with the presence of 15% or more bleeding sites. Poisson regression models were used to evaluate the association between gingivitis and overall and domain-specific CPQ11-14 scores. Prevalence of gingivitis at baseline was considered the main predictor for the OHRQoL at follow-up.
Gingivitis at baseline was associated with higher overall CPQ 11-14 score (RR = 1.07; 95%CI 1.01 - 1.14), and emotional well-being (RR = 1.17; 95%CI 1.04 - 1.31), independently of other oral conditions and socioeconomic variables.
The findings indicate that gingivitis negatively impacts the adolescents' OHRQoL. Moreover, gender, maternal schooling and household income were also associated with OHRQoL.
口腔健康相关生活质量（OHRQoL）受不同临床状况的影响。本研究的目的是评估牙龈炎对青少年OHRQoL的影响。
这项队列研究包括2012年在巴西圣玛丽亚随机抽取的1134名学童。两年后，对743名青少年进行了随访（应答率：65.5%）。收集了临床、社会经济和OHRQoL数据。OHRQoL通过巴西儿童感知问卷11 - 14简版（CPQ11 - 14）进行评估，牙龈出血通过社区牙周指数进行评估。存在15%或更多出血部位被视为患有牙龈炎。采用泊松回归模型评估牙龈炎与CPQ11 - 14总体得分及特定领域得分之间的关联。基线时牙龈炎的患病率被视为随访时OHRQoL的主要预测因素。
基线时的牙龈炎与较高的CPQ 11 - 14总体得分（RR = 1.07；95%CI 1.01 - 1.14）以及情绪健康（RR = 1.17；95%CI 1.04 - 1.31）相关，独立于其他口腔状况和社会经济变量。
研究结果表明，牙龈炎对青少年的OHRQoL有负面影响。此外，性别、母亲受教育程度和家庭收入也与OHRQoL相关。
