The aim of the present study was to analyse the association between socioeconomic and behavioural factors and the presence of active non-cavitated caries lesions in 12-year-old adolescents in Piracicaba, São Paulo, Brazil.
A cross-sectional study was carried out in 1001, 12-year-old adolescents who were selected by the cluster sampling method. A modified version of the World Health Organization criteria for identifying lesions including white lesions (WL) in enamel was used. Information on behavioural and socioeconomic factors was obtained using a semi-structured questionnaire. The outcome variables were DMFS, DMFS+WL and WL. The data obtained were analysed using the chi-square test and a logistic regression model.
The mean DMFS was 1.87 (SD = 3.05) and DMFS+WL was 2.27 (SD = 3.66). The logistic regression model showed that income was statistically significantly associated with DMFS, DMFS+WL and WL, whereas educational level of the father, number of residents in the house and number of dental visits were associated with DMFS and DMFS+WL. The onset of toothbrushing was associated with WL.
The present study showed that economic factors are associated with all stages of caries development. In addition to these factors, family size, number of dental visits, educational level of the father and onset of toothbrushing could be considered markers of dental health risk.
本研究旨在分析巴西圣保罗皮拉西卡巴12岁青少年的社会经济和行为因素与活动性非龋洞性龋损存在之间的关联。
采用整群抽样法对1001名12岁青少年进行了横断面研究。使用了世界卫生组织鉴定牙釉质病变（包括白色病变[WL]）标准的修订版。通过半结构化问卷获取行为和社会经济因素方面的信息。结果变量为龋失补牙面数（DMFS）、DMFS + WL和WL。使用卡方检验和逻辑回归模型对所得数据进行分析。
DMFS的均值为1.87（标准差 = 3.05），DMFS + WL为2.27（标准差 = 3.66）。逻辑回归模型显示，收入与DMFS、DMFS + WL和WL在统计学上显著相关，而父亲的教育水平、家庭居住人数和看牙次数与DMFS和DMFS + WL相关。开始刷牙的时间与WL相关。
本研究表明经济因素与龋病发展的各个阶段相关。除这些因素外，家庭规模、看牙次数、父亲的教育水平和开始刷牙的时间可被视为牙齿健康风险的标志。
