June 28, 2026 updated by: Advantage Silver Dental Arrest, LLC

Evaluation of the Response of Caries Lesions in Dentin After Application of Silver Diamine Fluoride Gel and Sodium Fluoride Varnish: A Single Group Observational Study

A single group observational study to determine the clinical response of dental caries lesions in primary teeth where 38% silver diamine fluoride gel is applied and cover with 2.5% sodium fluoride varnish. Additionally, to assess parent satisfaction with treatment with 38% silver diamine fluoride.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

A single group observational study of 235 children ages 3 and 4 with severe early childhood caries where the lesions are treated with 38% silver diamine fluoride and covered with 2.5% sodium fluoride varnish at baseline and 6 months. The primary objective is to determine the response of dental caries lesions (caries arrest) into the dentin in primary teeth at one year of follow-up. The secondary objective is to assess parent satisfaction with treatment with 38% silver diamine fluoride and 2.5% sodium fluoride varnish.

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
Lesion Activity
Time Frame: 12 months
Percentage of baseline d2/d3 caries lesions arrested at 12-month follow-up. The outcome measured on each participant is the percentage of baseline d2/d3 caries lesions arrested at 12-month follow-up. It is not a binary outcome measured at the participant level. To summarize the outcome the median value based on participants with 12 month follow-up is reported, along with the interquartile range (25th and 75th percentile) and 95% confidence interval. For surfaces scored from d1 through d4, the lesion was classi ed as active or inactive using an adaptation of criteria developed by Nyvad and colleagues (Nyvad B, Machiulskiene V, Baelum V. Reliability of a new caries diagnostic system differentiating between active and inactive caries lesions. Caries Res. 1999;33(4):252-260).
12 months
Lesion Activity
Time Frame: 5 months
Percentage of baseline d2/d3 caries lesions arrested at 5-month follow-up. The outcome measured on each participant is the percentage of baseline d2/d3 caries lesions arrested at 5-month follow-up. It is not a binary outcome measured at the participant level. To summarize the outcome the median value based on participants with 5 month follow-up is reported, along with the interquartile range (25th and 75th percentile) and 95% confidence interval. For surfaces scored from d1 through d4, the lesion was classi ed as active or inactive using an adaptation of criteria developed by Nyvad and colleagues (Nyvad B, Machiulskiene V, Baelum V. Reliability of a new caries diagnostic system differentiating between active and inactive caries lesions. Caries Res. 1999;33(4):252-260).

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
Caries Increment
Time Frame: 5 months
Number of new caries (d2-4mfs) from baseline to 5-month follow-up.
5 months
Caries Increment
Time Frame: 12 months
Number of new caries (d2-4mfs) from baseline to 12-month follow-up.
12 months
Incidence of (New) Caries Lesions
Time Frame: 5 months
The incidence of (new) caries lesions (d2-4mfs) per 1 surface-year at risk is the number of new caries lesions at 5 month divided by the surface time at risk between baseline and 5 months. The incidence is calculated for each participant and then summarized by the median, interquartile range (25th and 75th percentiles) and 95% confidence interval. The incidence rate is expressed as the number of new caries lesions per 1 surface-year at risk.
5 months
Incidence of (New) Caries Lesions
Time Frame: 12 months
The incidence of (new) caries lesions (d2-4mfs) per 1 surface-year at risk is the number of new caries lesions at 12 months divided by the surface time at risk between baseline and 5 months. The incidence is calculated for each participant and then summarized by the median, interquartile range (25th and 75th percentiles) and 95% confidence interval. The incidence rate is expressed as the number of new caries lesions per 1 surface-year at risk.
12 months
Satisfaction With Color Changes in Teeth
Time Frame: 12 months
Bothered by color changes in the teeth (1-10 scale), where 1 = not at all bothered and 10 = very bothered. Higher scores mean more bothered.
