Abstract

OBJECTIVE

To study the relationship between caries activity and the status of dental caries in preschool children using a caries activity test (CAT).

MATERIALS AND METHODS

The status of primary tooth caries in 229 children ages 3 to 5 was examined. Caries incidence, DFT, and caries severity index (CSI) were calculated. Based on the quantity of Streptococcus mutans in the oral cavity detected with Dentocult SM, a caries activity test, four grades of caries activity were classified: Grade 0 (< 10(4) colony-forming units/mL), Grade I (10(4)-10(5) CFU/mL), Grade II (10(5)-10(6) CFU/mL), and Grade III (> 10(6) CFU/mL).

RESULTS

The results showed that 79.48% children had Grade I or higher caries severity. Significant differences of caries activity were found among different grades, which were highly correlated with caries incidence, DFT, and CSI (r = 0.22216, 0.31212, and 0.32276, respectively).

CONCLUSIONS

As a CAT, Dentocult SM is a reliable method for measuring the status of dental caries in preschool children. It is also a valuable tool in the prevention and treatment of dental caries.

摘要

目的

使用龋活性试验（CAT）研究学龄前儿童龋活性与龋病状况之间的关系。

材料与方法

检查了229名3至5岁儿童的乳牙龋病状况。计算龋病发病率、龋失补牙数（DFT）和龋病严重程度指数（CSI）。根据用Dentocult SM（一种龋活性试验）检测到的口腔变形链球菌数量，将龋活性分为四个等级：0级（<10⁴菌落形成单位/毫升）、Ⅰ级（10⁴ - 10⁵CFU/毫升）、Ⅱ级（10⁵ - 10⁶CFU/毫升）和Ⅲ级（>10⁶CFU/毫升）。
