Our aim was to describe socio-economic and behavioural factors related to caries experience in school children in Sassari, Sardinia (Italy). Four hundred and three 12-year-old schoolchildren were randomly selected and their teeth clinically examined after air drying, under standard light using a plain mirror and WHO community periodontal index for treatment needs (CPITN) ballpoint probe. The clinical DMFS index was recorded following a diagnostic threshold, CPITN following the WHO indications. A questionnaire concerning oral hygiene habits (OHH), the onset of toothbrushing habits (OTH), frequency of dental check-ups (DCU), sweet food and soft drink consumption and socio-economic background factors, i.e. parents' occupational status (SOCFAM) and parents' age, was filled in by children and parent(s)/guardian(s). The caries prevalence was 61.6%. A positive skewness of DMFS was observed. Regarding caries, a significant linear trend (p<0.05) was found among odds ratios at each exposure level in SOCFAM, OHH, OTH and CPITN. A logistic regression model for caries was constructed using related factors. CPITN (gingival conditions) gave a significant contribution in the predictive model (p = 0.01). Gender acted as an effect modifier on CPITN, so logistic regression models were constructed for males and females separately. CPITN was the only statistically significant covariate in males and OHH the only one in females. Our results confirm a high caries prevalence and also a need for preventive and educational programmes for caries in Sardinia.
我们的目的是描述意大利撒丁岛萨萨里市学童龋齿经历相关的社会经济和行为因素。随机选取了403名12岁的学童，在空气干燥后，于标准光线下使用平面镜和世界卫生组织社区牙周治疗需要指数（CPITN）圆珠笔探针进行临床牙齿检查。按照诊断阈值记录临床DMFS指数，按照世界卫生组织的指示记录CPITN。孩子们及其父母/监护人填写了一份关于口腔卫生习惯（OHH）、刷牙习惯开始时间（OTH）、牙科检查频率（DCU）、甜食和软饮料消费以及社会经济背景因素（即父母职业状况（SOCFAM）和父母年龄）的问卷。龋齿患病率为61.6%。观察到DMFS呈正偏态分布。关于龋齿，在SOCFAM、OHH、OTH和CPITN的每个暴露水平的比值比之间发现了显著的线性趋势（p<0.05）。使用相关因素构建了龋齿的逻辑回归模型。CPITN（牙龈状况）在预测模型中做出了显著贡献（p = 0.01）。性别对CPITN起到了效应修饰作用，因此分别为男性和女性构建了逻辑回归模型。CPITN是男性中唯一具有统计学意义的协变量，而OHH是女性中唯一具有统计学意义的协变量。我们的结果证实了撒丁岛的高龋齿患病率，也表明需要开展龋齿预防和教育项目。
