Supplementary Material for: Association between sense of coherence and caries activity and caries experience among male adolescents from southern Brazil: a cross-sectional study

Introduction: This cross-sectional study assessed the association between sense of coherence (SoC) and caries activity (number of active caries lesions) and caries experience (DMFT index) among 18-19-year-old male adolescents who joined the Brazilian Army as draftees for mandatory military service (n=507). Methods: Data collection included a questionnaire (level of education, family income, and tooth brushing frequency), the Brazilian short version of the SoC scale (SOC-13), and clinical caries examination (non-cavitated/cavitated, inactive/active). The main predictor variable was SoC, categorized as low, moderate, or high. Poisson regression models were used for statistical analysis. Results: A high SoC was significantly associated with a lower number of active lesions (adjusted rate ratio = 0.85; 95% confidence interval = 0.74-0.98). No association between SoC and DMFT was detected. Conclusion: A high SoC was found to be a protective factor to caries activity in this population.引言：本横断面研究纳入507名以义务兵身份应征加入巴西军队的18~19岁男性青少年，旨在评估心理一致感（sense of coherence, SoC）与龋病活动度（活动龋损数量）及龋病患病经历（DMFT指数）之间的关联。 方法：数据采集包括问卷调查（收集受教育程度、家庭收入及刷牙频率信息）、巴西版简化心理一致感量表（SOC-13），以及临床龋病检查（对非龋洞/龋洞、静止/活动龋损进行分类评估）。本研究的主要预测变量为心理一致感，分为低、中、高三个等级。统计分析采用泊松回归模型。 结果：高心理一致感与较低的活动龋损数量显著相关（校正率比=0.85；95%置信区间=0.74~0.98）。未检测到心理一致感与DMFT指数存在关联。 结论：在本研究人群中，高心理一致感被证实为龋病活动度的保护因素。
