目的 调查北京市0～2岁儿童的患龋状况及检测Cariostat龋活跃性,探索该年龄段儿童菌斑产酸能力Cariostat值和低龄儿童龋(ECC)的关系。方法 以2016年3-9月北京市海淀区妇幼保健院儿童保健科1 123名0～2岁儿童为调查对象,进行口腔检查,并采集牙面软垢和菌斑的混合样本进行菌斑产酸能力Cariostat检测(北京冈大医疗科技有限公司),同时对母亲/监护人进行口腔健康检查和相关问卷调查。结果 该年龄段患龋率为13.2%,龋均(dmft)为0.44±1.35,龋严重程度指数(CSI)为1.86±6.42。患龋率、dmft、CSI及Cariostat值均随年龄增加而升高;患龋儿童的Cariostat 值分布区域明显高于无龋儿童,差异有统计学意义(P<0.001)。结论 菌斑的产酸能力Cariostat值能够反映该年龄段儿童的患龋状况,有助于龋风险评估及筛选龋高危儿童,并对该年龄段儿童个性化的龋病管理提供数据支持和指导依据。
Abstract
Objective To investigate the prevalence of early childhood caries(ECC) in children aged 0 to 2 years in Beijing,and to analyze the correlation between ECC and caries activity test(Cariostat score). Methods Totally 1 123 children aged 0 to 2 years from Haidian district in Beijing were examined by a cross-sectional sampling method from March to September 2016.The plaque samples were collected from buccal surfaces and incubated in the Cariostat test medium (Beijing GangDa Medical Technology CO., Ltd, China). Meanwhile mother/primary caregivers were also surveyed by oral health questionnaires. Results The ECC prevalence of children aged 0 to 2 years was found to be 13.2% with a mean decayed missed filled teeth(dmft) score of 0.44±1.35, and caries severe index(CSI)was 1.86±6.42.ECC, dmft, CSI and Cariostat value all increased significantly with age(P＜0.001).Cariostat test showed that most of the caries-free children were at lower level while most of the ECC children were at higher level(P＜0.001). Conclusions A strong correlation between the caries activity test (Cariostat score) and ECC exists in children aged 0 to 2 years.It is clear that Cariostat score can be used as an indicator for caries risk assessment and ECC prediction, and can provide reference for individualized management of caries.
