Clinical Study to Investigate the Antihypersensitivity Efficacy of a Novel Dentifrice

Running, not enrolling · Phase 3 · Has a placebo group

Conditions studied: Dentin Hypersensitivity

In brief

The aim of this clinical study is to demonstrate the superior antihypersensitivity efficacy of a novel stannous fluoride (SnF2) and potassium nitrate (KNO3) dentifrice (Investigational Product), compared to SnF2 only, KNO3 only and Vehicle dentifrices, after 8 weeks twice daily use.
