This study analyzes the methodological aspects of the SB Brasil epidemiological surveys conducted in 2003, 2010, and 2023. The sample plan, fieldwork, sampling process, investigated variables, and operational aspects were examined based on technical documents and relevant publications. All three surveys adopted complex, probabilistic cluster sampling, with different study domains and sample sizes across editions. Data collection was conducted by SUS workers in all three editions, and Community Health Agents (ACS) were included as data collector in 2023. In this edition, the listing process occurred in a separate phase before the interview and examination, in two stages, to update the address list and identify eligible residents. Data collection included oral examinations and household interviews. The health conditions and oral health indices, as well as the criteria for defining the assessed conditions for each age group, remained similar across surveys. SB Brasil 2023 introduced, for the first time, the evaluation of the clinical consequences of untreated dental caries and the intervention urgency. There was an expansion of demographic and socioeconomic variables and subjective aspects of oral health over the editions. Increasing incorporation of technologies for data recording was observed, with automation of the sample selection process and report generation to support fieldwork monitoring. These changes reflect a continuous commitment to producing high-quality data, essential for supporting public policies and strengthening oral health surveillance in Brazil.
本研究分析了2003年、2010年和2023年开展的巴西口腔健康调查（SB Brasil）的方法学方面。基于技术文件和相关出版物，对样本计划、实地调查、抽样过程、调查变量和操作方面进行了审查。所有三项调查均采用复杂的概率整群抽样，各版本的研究领域和样本量不同。在所有三个版本中，数据收集均由统一卫生系统（SUS）的工作人员进行，2023年将社区卫生工作者（ACS）纳入数据收集人员。在该版本中，列表过程在访谈和检查之前的一个单独阶段分两个阶段进行，以更新地址列表并确定符合条件的居民。数据收集包括口腔检查和家庭访谈。各调查中，健康状况和口腔健康指标以及各年龄组评估状况的定义标准保持相似。2023年的巴西口腔健康调查首次引入了对未经治疗龋齿的临床后果和干预紧迫性的评估。各版本中，人口统计学和社会经济变量以及口腔健康的主观方面有所扩展。观察到数据记录技术的使用不断增加，样本选择过程和报告生成实现自动化，以支持实地调查监测。这些变化反映了对提供高质量数据的持续承诺，这对于支持巴西的公共政策和加强口腔健康监测至关重要。
