Reducing social inequalities in the oral health of an adult population

Abstract The objective of this study was to evaluate the association between social inequality indicators and oral health conditions in an adult population. This prospective cohort study assessed a probabilistic sampling of adults (aged 20–64 years) living in Piracicaba, São Paulo, Brazil. Oral examinations were performed in 2011 and 2015, conducted at home, and used the decay-missing-filled (DMFT) index of permanent teeth, the Community Periodontal Index (CPI), and the visible biofilm criterion. A questionnaire was administered to determine demographic and socioeconomic aspects and dental services used, and collect oral health-related quality of life (OHRQoL) data. Social inequality indicators were evaluated according to social class (high, middle or low) and type of dental service used (public, health insurance or private), and compared with oral health conditions (visible biofilm, DMFT and incidence of tooth loss, periodontal pockets and bleeding, and OHRQoL), evaluated between 2011 and 2015. Analysis using chi-squared or Fisher tests (p

摘要 本研究旨在评估成年人群体中社会不平等指标与口腔健康状况之间的关联。本项前瞻性队列研究对巴西圣保罗州皮拉西卡巴市居住的20至64岁成年人群体进行了概率抽样评估。研究分别于2011年和2015年在家中开展口腔检查，检测指标包括永久牙龋失补指数（decay-missing-filled, DMFT）、社区牙周指数（Community Periodontal Index, CPI）以及可见菌斑判定标准。同时通过问卷调查收集人口统计学与社会经济特征、所使用的牙科服务信息，以及口腔健康相关生活质量（oral health-related quality of life, OHRQoL）数据。研究根据社会阶层（高、中、低）以及所使用的牙科服务类型（公立、医保覆盖、私立）对社会不平等指标进行评估，并与2011至2015年间评估的口腔健康状况（可见菌斑、DMFT指数、牙齿脱落发生率、牙周袋与牙龈出血情况，以及OHRQoL）进行对比分析。采用卡方检验或Fisher确切概率法进行分析（p
