Abstract
Recently prophylactic treatment for the increased dental caries of the infants has been proposed and systematic control to surpress the initiation of dental caries is desired.
In this paper, to collect the data related to the method of preventing dental caries, the questionnaires concerning 2,21/2,3 and 31/2 year old subjects at 9different areas were longitudinary analysed by the screening methor (presence or absence of dental caries or high or low of dental caries activity measured by Cariostat).
The results were as follows:
More items of the questionnaires were selected by the screening method with the presence of dental caries.
The selected items were almost entirely closely related to the dietary habit and especially related to the between-meal snacks (contents, regurality of taking, frequency. place to eat and etc. ).
Based on these results, the relationship of the dietary habit and dental caries of infants is proved more efficiently by the results of Cariostat than by the results of oral examination.
