Dental Plaque Prevention Efficacy of a Stannous Fluoride Toothpaste

February 12, 2026 updated by: Church & Dwight Company, Inc.

Dental Plaque Prevention Efficacy Evaluation and Comparison of a Stannous Fluoride Toothpaste

This randomized, stratified, double-blind, two-cell parallel clinical study evaluated the dental plaque prevention efficacy of a stannous fluoride toothpaste compared to a sodium fluoride control toothpaste following a professional dental prophylaxis. Adult subjects brushed twice daily for 14 days with their assigned dentifrice. Plaque was assessed using the Lobene-Soparkar modification of the Turesky Modification of the Quigley-Hein Plaque Index at baseline, Day 1, and Day 14 following periods of oral hygiene abstention.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This two-week, randomized, double-blind, parallel-group study evaluated plaque prevention following dental cleaning. Subjects meeting plaque qualification criteria underwent a complete prophylaxis and were randomized to either a stannous fluoride test dentifrice or a sodium fluoride control dentifrice. Subjects brushed twice daily for two minutes with the assigned product. Plaque accumulation was assessed at baseline, after one day of use, and after 14 days of use following overnight abstention from oral hygiene. Plaque was disclosed and scored on facial and lingual tooth surfaces using the Lobene-Soparkar modified Turesky Plaque Index. Treatment comparisons were performed using ANCOVA with baseline plaque as a covariate.

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.

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
Whole-Mouth Dental Plaque Score (Turesky Modified Quigley-Hein Index)
Time Frame: Day 14 (12 hours post-brushing following 14 days of twice-daily use)
Mean whole-mouth plaque index score assessed using the Lobene-Soparkar modification of the Turesky Modification of the Quigley-Hein Plaque Index. Treatment comparisons performed using ANCOVA with baseline plaque score as a covariate.
Day 14 (12 hours post-brushing following 14 days of twice-daily use)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Whole-Mouth Dental Plaque Score at Day 1
Time Frame: Day 1 (12 hours post-brushing)
Mean whole-mouth plaque index score assessed one day after initial supervised brushing.
Day 1 (12 hours post-brushing)
