A Clinical Study Investigating the Efficacy of an Occluding Dentifrice in Providing Relief From Dentinal Hypersensitivity

Supervised direct application (Day 0): Participants applied a pea-sized dose of test dentifrice to each of the 2 qualifying test teeth using their washed and clean finger to gently rub the dentifrice into the tooth's cervical margin for 60 sec. No rinsing was permitted after treatment. Supervised brushing (Day 0, before leaving the site) and Home use (3 days): after dosing a dry toothbrush with a full strip of dentifrice, participants brushed each of the 2 qualifying test teeth first, followed by their whole mouth for at least 60 sec. Participants were permitted to rinse with 5 mL tap water (room temperature) for 5 sec. maximum after brushing on supervised brushing (Day 0) and were also permitted to rinse with tap water after brushing on home use (3 days).

Supervised direct application (Day 0): participants applied a pea-sized dose of control dentifrice to each of the 2 qualifying test teeth using their washed and clean finger to gently rub the dentifrice into the tooth's cervical margin for 60 sec. No rinsing was permitted after treatment. Supervised brushing (Day 0, before leaving the site) and home use (3 days): after dosing a dry toothbrush with a full strip of dentifrice, participants brushed their whole mouth thoroughly for at least 60 sec. Participants were permitted to rinse with 5mL tap water (room temperature) for 5 sec. maximum after brushing in supervised brushing on Day 0 and were also permitted to rinse with tap water after brushing on home use (3 days).
