The Intraoral Cariogenicity Test in Young Subjects

Abstract
The applicability of the Intraoral Cariogenicity Test (ICT) was explored in young, fully dentulous subjects by using an orthodontic appliance to carry the test enamel slabs. In each subject, the degree of experimental caries that developed on the slabs proved to be characteristic of that individual. In all subjects, ICT results were relatively consistent for periods of weeks. However, over a period of months, two subjects displayed sharp changes. Experimental modification of individual factors affected ICT parameters in a predictable manner. The factors tested in this report showed that improved personal oral hygiene, or restriction of dietary sugars, reduced the severity of the experimental enamel lesions. Sorbitol, in extraoral supplementation, was less cariogenic than sucrose.
