Pre-Pasted Toothbrush Study (Must have a least one canker sore)

PROCEDURES: Visit 1: Potential subjects will report to the Testing Facility at their scheduled appointment time, with a clean mouth and freshly brushed teeth. Those who execute an ICF will become subjects. Subjects will complete a Medical History Form to determine initial qualification. Subjects will be screened by a Board-Certified Dentist for qualification into the trial. The Board-Certified Dentist will conduct a hard and soft tissue oral examination for signs of irritation (with the exception of canker sores). Subjects must present with at least one canker sore to qualify. With the exception of canker sores, subjects presenting a score of moderate (2) or greater for any one parameter will be disqualified. Qualified subjects will be provided with a 3-day supply of the test material, written and verbal instructions, and a daily diary to document use. Comments regarding test material experiences and attributes will be recorded on the daily diary. Each subject will be instructed to use the test material according to the Sponsor-supplied use instructions. Subjects may not introduce the use of any new oral care, cosmetic or personal care products during the trial. Visit 2: Subjects will report to the Testing Facility at their scheduled appointment time, with a clean mouth and freshly brushed teeth. Any unused test material will be collected. Daily diaries will be returned and reviewed for compliance. A Sponsor-supplied questionnaire will be completed by each subject and reviewed for completeness prior to subjects’ dismissal. Subjects will then be dismissed. *Subjects will be instructed to arrive to each visit with freshly brushed teeth
