目的：调查韦内托地区（意大利）幼儿园5岁儿童的龋齿经历和模式。研究设计：横断面研究。方法：研究于2005年9月至2006年5月进行，随机选择348名5岁儿童。两名校准牙医使用人造光，平面牙科镜和牙科探针进行临床牙科检查。世界卫生组织（WHO）龋齿诊断标准：dmft、dmfs和SiC指数用于衡量疾病的严重程度。统计数据：将dmfs评分作为连续变量（计算平均值和标准差）或分类变量（提供比例）进行分析。Pearson卡方检验用于组间比较，Wilcoxon符号秩检验用于相邻磨牙间dmfs评分的分布。结果：最常见的受影响的牙齿是乳磨牙，（总样本的78%），特别是在下颌骨。最常受影响的磨牙表面是咬合面（52%）。第一乳磨牙的近端面受影响程度大于第二乳磨牙。龋病以上颌骨最多见。前牙患龋率低（12%）。结论：乳牙期患龋呈对称性分布，主要集中在乳磨牙，以牙合面最多见。前牙龋不常见。
AIM: This was to investigate caries experience and patterns in a sample of 5-year-old children attending nursery schools in the Veneto Region (Italy). STUDY DESIGN: Cross sectional study. METHODS: The study was carried out between September 2005 and May 2006 with 348 randomly selected 5-year-old children. Two calibrated dentists using an artificial light, a plane dental mirror and a dental probe performed clinical dental examination. World Health Organisation (WHO) diagnostic criteria for dental caries: dmft, dmfs and SiC indexes were used to measure the severity of the disease. STATISTICS: dmfs scores were analysed either as a continuous continuous (calculating means and standard deviations) or as a categorical variable (providing proportions). Pearson's chi square test for comparison between groups and Wilcoxon signed-rank test for distribution of dmfs scores between pairs of contiguous molars were used. RESULTS: The most commonly affected teeth were primary molars, (78% of the overall sample), especially in the mandible. The surfaces of molars most often affected were the occlusal (52%). Proximal surfaces were affected more in first than in second primary molars. Dental caries occurred most often in the maxilla. The frequency of caries in anterior teeth was low (12%). CONCLUSIONS: Caries experience in the primary dentition showed a symmetrical distribution localized on primary molars, most often in their occlusal surface. Caries in anterior teeth was uncommon.
