Summary

This will be a randomized, controlled, single center, single- blind, 3 period, 3 treatment, cross-over, in situ design which consists of placing pre-eroded bovine enamel specimens intra orally using a palatal appliance and testing the remineralizing performance of the experimental (dentifrice containing 0.254 Percent weight by weight \[%, w/w\] sodium fluoride (1150 parts per million \[ppm\] fluoride) and 5% KNO3 \[potassium nitrate\]), comparator (dentifrice containing 0.454% w/w stannous fluoride (1100 ppm fluoride) and placebo (Fluoride free placebo containing 5% KNO3 \[0 ppm fluoride\] ) dentifrices 2 and 4 hours (hrs) post treatment application, based on surface micro hardness measurements. This study will be carried out in healthy adults with a maxillary dental arch suitable for the retention of the palatal appliance.

Conditions

  • Tooth Erosion

Interventions

DRUG

0.254% w/w sodium fluoride and 5% KNO3

Dentifrice containing 0.254% w/w sodium fluoride (1150 ppm fluoride) and 5% KNO3; plus 0.25% PVM/MA copolymer and 2.5% sodium lactate. Participants will brush it on the buccal surfaces of their natural teeth for 25 timed seconds and then swish the resulting toothpaste slurry around the mouth, without further brushing, for a timed period of 95 seconds. After expectorating the slurry, the participants will gently rinse their mouths with 15 millilitres \[mL\] of tap water for 10 seconds before expectorating again.

DRUG

0.454% w/w stannous fluoride

Dentifrice containing 0.454% w/w stannous fluoride (1100 ppm fluoride). Participants will brush it on the buccal surfaces of their natural teeth for 25 timed seconds and then swish the resulting toothpaste slurry around the mouth, without further brushing, for a timed period of 95 seconds. After expectorating the slurry, the participants will gently rinse their mouths with 15 mL of tap water for 10 seconds before expectorating again.

DRUG

5% KNO3

Fluoride free placebo dentifrice containing 5% KNO3 (0 ppm fluoride), 0.25% PVM/MA copolymer and 2.5% lactate. Participants will brush it on the buccal surfaces of their natural teeth for 25 timed seconds and then swish the resulting toothpaste slurry around the mouth, without further brushing, for a timed period of 95 seconds. After expectorating the slurry, the participants will gently rinse their mouths with 15 mL of tap water for 10 seconds before expectorating again.
