Conditions
- Tooth Erosion
Interventions
- Sodium fluoride
- Sodium monoflurophosphate
- Sterile water
Primary outcomes
- Adjusted Mean Percent Net Erosion Resistance (NER) of Enamel Specimens Exposed to Test Dentifrice + Test MR Relative to: 1) Test Dentifrice+ Sterile Water Rinse 2) Reference Dentifrice+ Sterile Water Rinse 3) Placebo Dentifrice+ Sterile Water Rinse — Baseline, 4 hours post treatment in each treatment period
Enamel specimens were exposed to dietary erosive challenge and set of five indentations within each specimen was measured. Decrease in the indentation length compared to the baseline indicates hardening of enamel surface. Enamel specimens were exposed to second erosion challenge to determine NER which compared the indentations values of enamel specimens at baseline (B), first erosive (E1) and second erosive challenge (E2). Percent NER was calculated by formula: \[(E1-E2)/ (E1-B)\]\*100. Smaller the negative NER, better is treatment regimen in imparting resistance to enamel.
