Abstract
We conducted overall research on the prevention and progress control of caries in infants. The subjects of this research were children from 1 to 15 years of age. We conducted this research from June to October of 1999. We distributed the Cariostat®, Mucount®, dental examination forms and questionnaries among the department of pediatric dentistry at 29 colleges and universities in Japan. We also researched the content of dental examination, the caries activity test and also the questionnaire survey. Based on the result we conducted the statistic processing on the subjects, especially on those in the survey ranging from 1 to 3 years of age and we obtained the following results.
1. There was a significantly relationship individually regarding Mucount®, CSI and Cariostat®, showing that these can be used for mesuring the actual satate of the oral cavity, in other words the caries activity in the mouth.
2. With considerable eating between meals, the drinking of spot beverages, and the delay in wearing, it was shown that the risk of caries become significantly higher.
3. The caries activity nature test can be used for showing the risk of caries.
