About this study

Official title: Prospective Cohort Study: Efficacy of the Use of 38% Silver Diamine Fluoride and 5% Sodium Fluoride Varnish in Patients 4 to 12 Years for the Treatment of Caries and Its Association With Other Aspects of Relevance

The goal of this observational study is to identify the efficacy of silver diamine fluoride 38% followed by sodium fluoride varnish 5% in a population with untreated dental caries age range 4 to 12 years old. The main questions to answer are

  • Efficacy of treatment of active tooth decay with the treatment protocol of 38% silver diamine fluoride and 5% sodium fluoride varnish.
  • Clinical evaluation of tooth decay treated with 38% silver diamine fluoride and 5% sodium fluoride varnish in quality of hardness, color change and caries progression.
  • Explore the association of treatment with 38% silver diamine fluoride and 5% sodium fluoride varnish with: i. Reduction of oral pain caused by the presence of carious lesions. ii. Improvement in gingival oral health. iii. Changes in general nutritional status through measurements of height, weight, hemoglobin levels and nutritional survey. The participants will be identified, charted (with nutritional surveys and parameters), as well as treated and compared in a six- and twelve-month period, where researchers will clinically identify the association between the use of this protocol and the efficacy of such, as well as other related nutritional aspects.

Questions about this trial

What is this clinical trial studying?

An observational study of Dental Caries in Children, run by Universidad Mayor de San Simón at 1 site in Bolivia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Bolivia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Ratio of arrested cavity lesions after treatment with 38% silver diamine fluoride and 5% sodium fluoride varnish (time frame: 6 months from initial treatment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2023.
