Details and patient eligibility

About

To evaluate and compare plaque removal efficacy and safety of a novel dentifrice formulation immediately after the first supervised use and following one week of twice, daily use at home.

Full description

Study participants brushed their teeth for one minute, two times daily, for seven days.

Participants who met study entry criteria were randomized to either the test (Protegera™) or control (Crest™ Cavity Protection) toothpaste, and each were given the same straight, soft bristled toothbrush to use throughout the study.

On Day 1, participants were given an oral exam, and a pre-brushing plaque score was recorded. Participants then brushed their teeth for one minute under supervision, and a post-brushing plaque score was recorded.

On Day 7, participants were given an oral exam, and a pre-brushing plaque score was recorded. Participants then brushed their teeth for one minute under supervision, and a post-brushing plaque score was recorded.

Have agreed not to have a dental prophylaxis or any other elective, non-emergency dental procedures (other than those provided during the study) any time during the 7-day study.
Have been willing to refrain from all oral hygiene procedures (including chewing gum) for 24 hrs. and refrained from eating, drinking and smoking for approximately 2 hours prior to Visits 1 & 2.
Have agreed to refrain from use of all oral hygiene products (i.e., floss, mouthwash, etc.), other than the toothbrush and toothpaste supplied, for the duration of the 7-day study.

Had severe periodontal disease or being actively treated for periodontal disease.
Had fixed or removable orthodontic appliances, bridges, peri/oral piercings, or removable partial dentures.
Had significant oral soft tissue pathology based on a visual examination baseline.
Had evidence of poor oral hygiene or rampant dental caries or presence of extrinsic stain or calculus deposits that may interfere with plaque assessments.
Had received a dental prophylaxis within 30-days prior to Visit 1.
Had participated in another dental research study within 30-days prior to Visit 1.
