Trial Outcomes & Findings for Study of the Anti-Inflammatory Effects of Colgate Total® During an Experimental Gingivitis Model (NCT NCT01799226)

NCT ID: NCT01799226

Last Updated: 2016-01-13

Results Overview

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.

Participant Flow

Initially 15 participants were sought for each arm, but when two were withdrawn from the control arm, two more participants were recruited and randomized, one to each arm. So total start on each arm was 16. The Disqualification noted below for one participant was because s/he no longer met inclusion criteria as of day 14.

Participant milestones
Measure
Control Arm
Participants were randomly assigned to either the test (triclosan dentifrice) or control (fluoride dentifrice) arm of the study and to either the right or left stent side. The control dentifrice was composed of 0.76% sodium monofluorophosphate 1000 ppm (0.15% w/v fluoride ion) as the active ingredient along with inactive ingredients (Colgate® Cavity Protection Great Regular Flavor Fluoride Toothpaste).
Test Arm
Participants were randomly assigned to either the test (triclosan dentifrice) or control (fluoride dentifrice) arm of the study and to either the right or left stent side. The test dentifrice was composed of 0.24% sodium fluoride 1100 ppm 0.243% (0.14% w/v fluoride ion) and triclosan 0.30% in combination with 2% polyvinyl methyl ether maleic acid copolymer as the active ingredients along with inactive ingredients (Colgate® Total® Clean Mint Paste).

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline to 35 Days

Inflammatory biomarker expression will be quantified using a custom human 10-complex protein array that is optimized for sensitivity, specificity, stability, and intraassay coefficient of variation by comparing to single cytokine enzyme-linked immunosorbent assays (Quantibody Custom Array, RayBiotech, Norcross, GA).

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline to 35 Days

Supra- and sub-gingival plaque samples will be gently collected using a sterile curet and a one stroke method from two randomized sites within the stent area. The detection of 40 bacterial species will be evaluated by the checkerboard DNA-DNA hybridization technique originally described by Socransky et al. 1994.

A total of 10 biomarkers will be analyzed based on the results from Lee and colleagues: IL-1α, IL-1β, IL-6, IL-8, IL-10, MCP-1, MMP-8, MMP-9, TIMP-1, and TIMP-2.
