A Study of the Mailing Method of the Cariostat Test

An Investigation of the Mailing Condition

Abstract

The purpose of this study was to investigate usefulness of the mailing method of the Cariostat test. The subjects were 50 adults. Two dental plaque samples were taken from one subject at a time, and the operation was repeated four times per week. Some plaque samples were put into the Cariostat medium and incubated at 37°C for seventy-two hours. The Cariostat value and the pH value were evaluated for each twenty-four hours. Other plaque samples were mailed under four conditions (the group of the mailing method with only one swab at normal temperature, the group of the mailing method with the swab put into the Cariostat medium at normal temperature, the group of the mailing method with only one swab at low temperature, and the group of the mailing method with swab put into the Cariostat medium at low temperature), and then was operated as well as that regular method. The results were as follows;
1. The average pH value for the group of the mailing method with only one swab at normal temperature was highest of the four groups.
2. The correlation coefficient between the pH values for the group of mailing method with only one swab at low temperature and the group of the regular method was most statistically significant.
