Conditions

Dental Caries

Brief summary

This is a double blind, cross-over, controlled clinical trial utilizing thirty (30) adults to evaluate remineralization of early caries lesions.

Interventions

DRUGControl toothpaste containing no anti-cavity ingredients

Brush whole mouth with study toothpaste 2x/day for the 2 week test period. Each brushing routine is 1 minute whole mouth brushing with oral retainer in mouth, spit out toothpaste residue and wait for 1 minute before rinsing with water.

DRUGExperimental toothpaste containing fluoride and amino acid (arginine)

Brush whole mouth with study toothpaste 2x/day for the 2 week test period. Each brushing routine is 1 minute whole mouth brushing with oral retainer in mouth, spit out toothpaste residue and wait for 1 minute before rinsing with water.

DRUGFluoride toothpaste containing fluoride as the anti-cavity ingredient

Brush whole mouth with study toothpaste 2x/day for the 2 week test period. Each brushing routine is 1 minute whole mouth brushing with oral retainer in mouth, spit out toothpaste residue and wait for 1 minute before rinsing with water.

Design outcomes

Primary

MeasureTime frameDescription
Mineral Change (delta Z)BaselineTooth samples of human enamel are placed in a retainer and worn by each study subject. Enamel block samples will be x-rayed and analyzed for mineral level (volume % of micrometer of lesions , vol% µm) before being placed in the retainer. These baseline values will be compared with the post use delta mineral change (∆ Z).
