In-situ Evaluation of Anti-caries Technology - Full Text View

Purpose

Three toothpastes will be compared, two toothpastes in each subject, to establish whether changes in the depth or area of an artificially created area of tooth decay is the same for each toothpaste.

Primary Outcome Measures:

Change in depth of artificial lesion over 3 months [ Time Frame: 3 months ]
Comparison of two 950 ppm fluoride containing dentrifices, Clinpro Toothcreme and MI Paste Plus, with fluoride-free dentrifice (Toms of Maine)for any change in artificial lesion depth due to demineralization or remineralization over the time period of the study
Change in area of artificial lesion over 3 months [ Time Frame: 3 months ]
Comparison of two 950 ppm fluoride containing dentrifices, Clinpro 5000 and MI Paste Plus, with fluoride-free dentrifice (Toms of Maine) for any change in artificial lesion area due to demineralization or remineralization over time period of study

Groups/Cohorts	Assigned Interventions
Group A Clinpro 5000	Device: Clinpro 5000 Dentrifice containing 950ppm fluoride
Group B MI Paste Plus	Device: MI Paste Plus Dentrifice containing 950ppm fluoride
Group C Toms of Maine	Device: Tom's of Maine Dentrifice that is fluoride free

Detailed Description:

Objective is to evaluate the demineralization and remineralization effects of two experimental fluoride containing dentrifices on enamel and root surface lesions compared with a control dentrifice.

Study is a partially randomized, 3-period cross over study involving 30 subjects who need a full-coverage crown on a posterior tooth. Each subject will use each of the study dentrifices over 3 months according to a randomization scheme. Subjects will brush daily with the assigned dentrifice unsupervised. Subjects will each have two provisonal crowns for use during the study. These crowns will contain three hard tooth tissue sections located at interproximal sites. The three tooth tissue slabs will consist of an artificial enamel caries lesion, an artificial root caries lesion, and a sound root. After removal, the tooth slabs will be evaluated using polarized light and photomicrographs for changes in area and depth of lesions.
