The aim of this study was to investigate the association between periodontal disease and self-rated oral health among Brazilian adults.
Data on 11,874 adults in 250 cities from all the Brazilian regions were analysed. The outcome investigated was self-rated oral health (dichotomized into "Good" and "Poor") and the main exposure was periodontal disease defined as the combination of periodontal pocket depth >or=4 mm and clinical attachment loss >or=4 mm. Demographic characteristics, socioeconomic conditions, clinical oral health conditions (dental caries, dental and gingival pain, tooth loss and use of prosthesis) and use of dental services were the other explanatory variables. Simple and multivariate Poisson regression was performed allowing the estimation of prevalence ratios (PRs). All analyses were adjusted for the cluster sampling design.
The prevalence of periodontal disease was 8.9% ((95%)CI 7.6-10.3) and poor self-rated oral health was 23.6% ((95%)CI 21.9-25.2) which was significantly higher among those who presented periodontal disease (PR 1.4; (95%)CI 1.2-1.5), after the adjustment for possible confounders.
Periodontal disease was associated with poor self-rated oral health. The results of this study should be considered by population health planners in order to assess and plan periodontal services.
本研究旨在调查巴西成年人牙周疾病与自评口腔健康之间的关联。
分析了来自巴西所有地区250个城市的11874名成年人的数据。所调查的结果是自评口腔健康（分为“良好”和“较差”），主要暴露因素是牙周疾病，定义为牙周袋深度≥4毫米和临床附着丧失≥4毫米的组合。人口统计学特征、社会经济状况、临床口腔健康状况（龋齿、牙齿和牙龈疼痛、牙齿缺失和假牙使用情况）以及牙科服务的使用是其他解释变量。进行了简单和多变量泊松回归，以估计患病率比（PRs）。所有分析均针对整群抽样设计进行了调整。
牙周疾病的患病率为8.9%（（95%）可信区间7.6 - 10.3），自评口腔健康较差的患病率为23.6%（（95%）可信区间21.9 - 25.2），在调整可能的混杂因素后，牙周疾病患者中该患病率显著更高（PR 1.4；（95%）可信区间1.2 - 1.5）。
牙周疾病与自评口腔健康较差有关。人群健康规划者应考虑本研究结果，以便评估和规划牙周服务。
