Arms Assigned Interventions
Active Comparator: Toothpaste without Triclosan
This arm will use a toothpaste that does not contain triclosan
Other: Toothpaste without triclosan
this intervention will use a toothpaste without triclosan
Experimental: Triclosan
This arm will use colgate total which contains triclosan
Other: Triclosan
this intervention will use Colgate Total which contains triclosan
Other Name: Colgate total toothpaste

Detailed Description:

This will be a double-blind, parallel group study utilizing the experimental gingivitis model. Subjects will be randomly assigned to an arm of the study. Enrolled subjects will also be randomly assigned to either right or left side mandibular stent.

Saliva and gingival crevicular fluid and plaque samples will be collected at Day 0, 14, 21, and 35 study visits. A randomization chart will be used to identify which two sites (teeth and tooth surface) will be used at the specific study visit for collection of gingival crevicular fluid(GCF)and plaque. Gingival crevicular fluid (GCF) and plaque samples will not be taken from implants. If one of the posterior teeth is missing, the cuspid tooth will be used as a substitute tooth. Repeat gingival crevicular fluid (GCF) samples will be taken at Day 14, and 21.


Ages Eligible for Study:   18 Years to 40 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Race - all
  • Gender - female or male
  • Age - 18 to 40 years old
  • Dentition - minimum of 20 permanent teeth
  • Probing Pocket Depth of 4mm in all sites
  • Mean Clinical Attachment Levels of 2mm on all teeth
  • Bleeding Upon Probing of greater than 30% at Day -14 Study Visit
  • Consent Form - read, understood, and signed
  • Study Procedures - willing to follow all study procedures
  • At Day 0 Study Visit, all subjects must have a BOP of less than 10%. Subjects not meeting the BOP study criteria will be asked to return in 2 weeks for a second assessment visit. Subjects who do not meet the inclusion criteria
  • BOP less than 10% at the second assessment visit will be exited from the
  • study

Exclusion Criteria:

  • Medical History - a history of alcoholism or drug abuse
  • Diseases of the immune system
  • Medical condition that may affect outcome (neurologic or psychiatric disorders, systemic infection
  • Medications - chronic medications known to affect the periodontal status (calcium antagonists anticonvulsives, immunosuppressives, anti-inflammatory medications, phenytoin, Depo-Provera contraceptive injection users
  • New oral contraceptives users within 3 months of baseline or are planning on starting oral contraceptives during the study
  • Hypersensitivity - previous known reaction to or oral allergy to any ingredient in the study toothpaste
  • Antibiotics - antibiotic therapy within 3 months of baseline visit
  • antibiotic therapy needed for infective endocarditis prophylaxis or total joint replacement
  • Use of antiseptics - homecare regime using products to control dental plaque formation within 30 days prior to baseline visit
  • Smoking - current smokers, smokers who quit smoking less than one year ago, or a pack-year history of more than or equal to 10 (pack-years will be calculated by multiplying the number of years smoked by the average number of cigarette packs smoked per day)
  • Continine - positive urine analysis results
  • Current Dental Treatment - orthodontic or periodontal treatment
  • Untreated Dental Treatment - untreated carious lesions
