Study of the Anti-Inflammatory Effects of Colgate Total® During an Experimental Gingivitis Model

Not Applicable

Completed

• Conditions: Gingivitis
• Interventions: Other: Triclosan; Other: Toothpaste without triclosan

• Registration Number: NCT01799226
• Lead Sponsor: University of Michigan

Brief Summary

This study evaluates the anti-inflammatory effects of Colgate Total® during an experimental gingivitis model developed by Löe et al. Half of the participants will use Colgate Total® (which contains triclosan), while the other half will use a toothpaste which does not contain triclosan as the control.

Detailed Description

This will be a double-blind. Subjects will be randomly assigned to the test or control dentifrice arm. Enrolled subjects will also be randomly assigned to either right or left side mandibular stent.

During the induction phase (i.e., day 0 to day 21), participants are instructed to refrain from all hygiene procedures in the stent area. During this time period, participants evenly distributed 2mL of their assigned dentifrice into their stent, allowing it to come into contact with the areas of experimental gingivitis for two minutes twice daily while traditional tooth brushing was performed in the non-stent areas. Clinical measures, saliva, gingival crevicular fluid and plaque samples will be collected at days 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.

Arm && Interventions

Group	Intervention	Description
Triclosan	Triclosan	This arm will use colgate total which contains triclosan
Toothpaste without Triclosan	Toothpaste without triclosan	This arm will use a toothpaste that does not contain triclosan

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Plaque Index (Silness & Loe 1964) to Day 35	Baseline to 35 Days	Silness \& Loe 1964 is a score of 0-3 with 0 = No plaque, 1 = A film of plaque adhering to free gingival margin and adjacent area of tooth. The plaque may be seen in situ only after application of disclosing solution or by using the probe on the tooth surface, 2 = Moderate accumulation of soft deposits within the gingival pocket, or on the tooth and gingival margin, which can be seen with the naked eye, 3 = Abundance of soft matter within the gingival pocket and/or on the tooth and gingival margin. This index was used at days 0, 14, 21 and 35.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Gingival Index (Loe & Silness 1963) to Day 35	Baseline to 35 Days	Loe \& Silness 1963 is a score of 0-3 with 0 = Absence of inflammation, 1 = Mild inflammation, slight change in color and texture, 2 = Moderate inflammation, glazing, redness, edema and hypertrophy, 3 = Severe inflammation, redness and hypertrophy, ulceration. This index was used at days 0, 14, 21 and 35.
