目的:了解澳门地区幼儿乳牙患龋状况及其龋病活跃性,并作两者间关系分析,填补该地区资料的空白。方法:对澳门生活环境、经济条件等有较大差异的两所幼儿园2～4岁930名幼儿作龋蚀程度检查和记录;其中910名幼儿并作龋病活跃性检测SCAT,依据牙菌斑产酸能力强度分度。统计分析患龋率,龋均dft、龋蚀严重度指数CSI和SCAT。结果:①2～4岁930名幼儿乳牙患龋率为42.5%、dft1.93、CSI6.35,性别间无显著性差异(P>0.05)。②患龋率、dft、CSI在年龄组间均有显著性差异。③两幼儿园间,患龋率、dft、CSI均有明显差异。④910名幼儿SCAT0度和1度占68.68%,2度和3度占31.32%。⑤两幼儿园间SCAT各度的分布有明显差异。⑥SCAT各度间,患龋率、dft、CSI均有明显差异,dft、CSI与SCAT相关性有显著意义。结论:①澳门幼儿患龋状况不容忽视。应抓紧低年龄幼儿的龋病防治工作。②儿童所处的不同生活条件可影响患龋状况,普及科普知识、维护口腔卫生、开展定期防治等的推广尤有必要。③SCAT能反映患龋状况的敏感度,在筛选幼儿龋病高危群体、有的放矢开展龋病防治计划工作中,既能节省人力、财力、又能提高效率。
Objective: To understand the prevalence of caries in deciduous teeth and the prevalence of caries in young children in Macao and to analyze the relationship between them and to fill the gaps in the data in this area. Methods: Coronary heart disease (930) children aged 2 to 4 years in two kindergartens with different living conditions and economic conditions in Macao were examined for cariogenicity. Among them 910 children were tested for cariogenic activity by SCAT, Acid production capacity indexing. Statistical analysis of caries prevalence, caries were dft, cariousness index CSI and SCAT. Results: ① The prevalence of dental caries among 930 infants younger than 2 years old was 42.5%, dft1.93 and CSI6.35, respectively. There was no significant difference between the sexes (P> 0.05). ② caries rate, dft, CSI in the age groups were significantly different. ③ between two kindergartens, caries prevalence, dft, CSI were significantly different. ④910 children SCAT0 degrees and 1 degree accounted for 68.68%, 2 degrees and 3 degrees accounted for 31.32%. ⑤ SCAT between the two kindergartens have obvious differences in the distribution. ⑥SCAT degrees, caries prevalence, dft, CSI were significantly different, dft, CSI and SCAT significant correlation. Conclusion: ① The caries in children in Macao can not be ignored. We should pay close attention to caries prevention and treatment of young children. ② Children living in different conditions can affect the status of caries, popularization of popular science knowledge, to maintain oral hygiene, to carry out regular prevention and treatment of the promotion of even more necessary. ③ SCAT can reflect the sensitivity of caries status. In screening high-risk groups of caries in children, targeted caries prevention and control plan can not only save manpower and financial resources, but also improve efficiency.
