Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 3 to 17 years
  • All sexes
  • No healthy volunteers
  • Child

Who may be able to join

  • Primary teeth: distal surface of the first molar, mesial surface of the second molar and distal surface of the second molar (when the first permanent molar is present) with initial caries lesion (ICDAS 1, 2 or 3).
  • Permanent teeth: distal surface of the first premolar, mesial surface of the second premolar, distal surface of the second premolar, mesial surface of the first molar, distal surface of the first molar and mesial surface of the second molar with initial caries lesion (ICDAS 1, 2 or 3).

Who cannot join

  • Mesial surface of the first primary molar/premolar by the smaller contact with the distal surface of the canines. It will be also excluded the surfaces that show proximal restorations, sealants, cavities, defects, as well as intact teeth.

About this study

Official title: Treatment of Initial Caries Lesions on Proximal Surfaces of Primary and Permanent Posterior Teeth: a Randomized Placebo-controlled Study.

This study aims to evaluate the effectiveness of 30% silver diamine fluoride in the treatment of clinically caries lesions in enamel, with radiographic image restricted to the enamel or the outer third of dentin on the proximal surfaces of primary and permanent posterior teeth. It also aims to compare it to the resin infiltration and to the control of proximal biofilm through the oral hygiene.

Read the detailed description

The sample will be comprised of 141 patients between 3 to 10 year-old and 504 proximal surfaces of 12-to-17-year-old adolescents, who present at least one proximal surface with initial caries lesion. Patients will be randomly allocated to treatments, according to the technique to be employed: (I) resin infiltration (II) 30% diamine silver fluoride, (III) just daily flossing by the patient. All subjects will receive placebo treatments performed in other groups. The teeth will be evaluated by clinical and radiographic exams at baseline and after 1, 3, 6, 12, 18 and 24 months. In 1, 3 and 18 months will just be evaluated aspects related to the biofilm.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Resin InfiltrationProcedure or surgery

    Also called Icon

    After cleaning the proximal surface with caries lesion, it will be performed the local infiltration anesthesia and adaptation of the rubber dam. The adjacent tooth will be protected by plastic or metal strip. Hydrochloric acid 15% will be applied on the lesion, which will be washed and dried. The surface should be dried by applying 95% ethanol and air-way syringe. The resin infiltration (Icon, DMG) will be applied on the lesion. The resin will be polymerized and applied again and polymerized.

  • 30% Silver Diammine FluorideProcedure or surgery

    Also called Cariestop

    It will be cleaned like group I. Soft tissues will be protected with petroleum jelly. The 30% silver diamine fluoride (Cariestop, Biodinamica) will be applied with a disposable microbrush for 3m. Then the surface will be washed for 30s.

  • Dental FlossingProcedure or surgery

    Also called Oral hygiene

    In this group, the patient will perform only mechanical removal of biofilm to floss daily.

  • Resin Infiltration PlaceboProcedure or surgery

    Also called Icon Placebo

    In this group, the patient will be held only inserting the rubber dam and applied sterile water as a substitute for acid, ethanol and resin infiltration.

  • 30% Silver Diammine Fluoride PlaceboProcedure or surgery

    Also called Cariestop Placebo

    Soft tissues will be protected with petroleum jelly. The patient will receive sterile water application with a disposable microbrush for 3m. Then the surface will be washed for 30s.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 4 May 2016. 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 Brazil. 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?

Results are not available in the source record.

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

Contact Mariana M Braga, PhD (55 11 30917835, mmbraga@usp.br), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

progression of initial lesion caries (time frame: 12 and 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01477385, which also lists 2 linked publications.

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?
