Clinical Evaluation of the Efficacy of a Marketed Dentifrice on Plaque and Gingivitis

April 19, 2021 updated by: Church & Dwight Company, Inc.
Parallel, double blind, randomized, Institutional Review Board (IRB) -approved study involving approximately 160 subjects to complete. Subjects were randomly assigned to either the test product (Arm & Hammer Advance White Brilliant Sparkle) or the control (Crest Cavity Protection Regular) based on baseline mean whole-mouth plaque and gingival scores and age.Subjects brushed with their assigned dentifrice two times (2X) daily and were evaluated for gingivitis, bleeding and plaque at Baseline and after 4-, 8-, and 12-weeks of product use. Return to pre-study hygiene regimen for 4 weeks and final evaluation at 16 weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Within-Treatment Whole-Mouth Differences (vs Baseline) - Gingival Efficacy
Time Frame: 16 weeks
change in score as measured by Gingival Index (0=absence of inflammation, 1=mild inflammation: slight change in color, little change in texture of any portion of but not the entire marginal or papillary gingival unit, 2=mild inflammation: slight change in color, little change in texture to entire marginal or papillary gingival unit, 3=moderate inflammation: glazing, redness, edema and/or hypertrophy of the marginal or papillary gingival unit, 4=severe inflammation: marked redness, edema and/or hypertrophy of the marginal or papillary gingival unit, spontaneous bleeding, congestion, or ulceration. The scale ranges from 0-4.
16 weeks
Within-Treatment Whole-Mouth Differences (vs Baseline) Gingival Bleeding Efficacy
Time Frame: 16 weeks
change in score as measured by Gingival Bleeding Index (0=absence of bleeding after 30 seconds, 1= bleeding observed after 30 seconds, 2= bleeding occurs instantly). The scale ranges from 0-2.
16 weeks
Within-Treatment Whole-Mouth Differences (vs Baseline) - Plaque Efficacy
Time Frame: 16 weeks
change in score as measured by Plaque Index (0=no visible plaque, 1=separate flecks of plaque at the cervical margin of the tooth, 2=a thin, continuous band of plaque (up to 1mm wide) at the cervical margin, 3= a band of plaque wider than 1 mm but covering less than one-third of the crown, 4=plaque covering at least one-third but less than two-thirds of the crown, 5= plaque covering two-thirds or more of the crown. The scale ranges from 0-5.
