About this study

Official title: Cost-efficacy and Applicability of the Treatment of Moderate Caries Using Sealants as an Alternative to the Restorations on Occlusal Surfaces of Deciduous Teeth: a Randomized Controlled Trial

This protocol aims to assess the cost-efficacy and applicability of the treatment of lesions moderate caries using sealants as an alternative to the restorations on occlusal surfaces of deciduous teeth. Initially, a non-inferiority study was designed in order to verify if sealing could be non-inferior than restoration. In this case, it could be preferable since it is less invasive. Therefore, cost will be put forward into the analysis considering even reintervention during the follow-ups (cost-efficacy analyses). Finally, the acceptability could be another differential point between treatments.

Read the detailed description

This study aims to evaluate the cost-efficacy and applicability of the treatment of lesions moderate caries using sealants as an alternative to the restorations on occlusal surfaces of deciduous teeth. 96 children aged 3-6 years will be selected. Children must have at least one occlusal surface classified as scores 3 or 4 of International Caries Detection and Assessment System (ICDAS). Children will be randomly allocated according to the treatment: glass ionomer sealant and restoration with glass ionomer. After treatment, teeth will be assessed clinically after 6, 12, 18 and 24 months by trained and blinded examiners regarding the treatment received. The need of reintervention initially treated, either by failures that require repeating of the same procedure or for progression of caries lesions will be considered as primary outcomes. The secondary outcomes will be the chil's acceptability to the treatment.

What participants receive

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

  • Ionomer Restoration (control)Procedure or surgery

    Also called glass ionomer cement, restoration

    Restoration of moderate caries lesions after partial caries removal using high viscosity glass ionomer cements

  • Ionomer Sealant (test)Procedure or surgery

    Also called glass ionomer cement, sealant

    Sealing of moderate caries lesions without any caries removal or cavity opening.

  • Oral hygiene orientation and professional fluoride applicationProcedure or surgery

    Oral hygiene orientation and professional fluoride application

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Need of reintervention

    Need of reintervention will be considered as all failures after initial treatment that demand repair and/or caries progression associated to the treated lesion at baseline.

    After cleaning, It will be analyzed the clinical evaluation of restorations and sealants, will be assessed the presence of caries lesions in dentin and / or evolution of ICDAS scores and if will be necessary other types of treatment, such as endodontics and extraction of teeth included.

    Measured: 24 months

Secondary outcomes (2)
  1. Child's reported discomfort

    The discomfort will be an outcome collected right after the end of treatment, using Wong baker scale

    Measured: 1st day

  2. Duration of treatments

    Time spent in interventions will be recorded.

    Measured: 1st day

Questions about this trial

What is this clinical trial studying?

A study testing Ionomer Sealant (test) and Oral hygiene orientation and professional fluoride application in people with Dental Caries, run by University of Sao Paulo at 1 site in Brazil.

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 3 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 22 Mar 2018. 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?

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?

Need of reintervention (time frame: 24 months). 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 22 Mar 2018.
