About this study

In front of a lack of evidence to determine the best treatment for deep cavitated carious lesions, the search for an effective restorative technique, which results in a least possible discomfort to patients, and reduce the time needed for the restorative treatment, if becomes relevant. The objective of this randomized clinical trial to evaluate the efficacy of high viscosity glass ionomer cement restorations (HVGIC) compared to restoration with calcium hydroxide restoration associated with high viscosity glass ionomer cement (HVGIC) for treatment of deep lesions in primary molars, as well as the impact of treatment in the criteria focused on the patient as well as cost-efficacy of the techniques . Children with 4 to 8 years will be selected randomly at the Clinic for Children at the University Ibirapuera of Dentistry. 108 teeth will be randomized into two groups: (1) restoration with calcium hydroxide cement associated with HVGIC and (2) HVGIC restoration. The restorations will be evaluated after 6, 12 and 24 months by two trained examiners blinded to the treatments. The efficacy of each treatment is measured by four main outcomes, which are: (1) criteria related to the effectiveness of the restorative treatment (2) criteria focused on the patient and (3) cost-efficacy. For comparison between the two groups will be used the Kaplan-Meier survival and the long-rank test. Cox regression is performed the assessment of the influence of some other variable results. For all analyzes, the significance level is set at 5%.

Being tested
HVGIC, Indirect pulp capping

What participants receive

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

  • HVGICOther

    In experimental group, the researches will be performed a restoration, after partial caries removal, with high viscosity glass ionomer cement in the teeth with deep caries lesion.

  • Indirect pulp cappingOther

    In control group, the researches will be performed a indirect pulp capping with calcium hydroxide cement and high viscosity glass ionomer cement in the teeth with deep caries lesion.

What is being measured

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

  1. Pulp Vitality

    To evaluate the survival of different restorative treatments considering the pulp vitality.

    Measured: Up to 24 months

Secondary outcomes (4)
  1. Wong-Baker scale to discomfort

    To evaluate the discomfort of different restorative treatments by a Wong-Baker scale.

    Measured: Immediately to restoration procedure.

  2. Cost-efficacy analysis by total value of treatment in relation to efficacy

    To evaluate the cost-efficacy of different restorative treatments by total value in dollar of treatment in relation to efficacy. The researchers would like to analyze that a treatment of low cost show the similar efficacy of a high cost treatment.

    Measured: Up to 24 months

  3. Restoration longevity

    To evaluate the restoration longevity by clinical examination.

    Measured: Up to 24 months.

  4. Caries progression

    To evaluate the caries progression by radiography.

    Measured: Up to 24 months.

Questions about this trial

What is this clinical trial studying?

A study testing HVGIC and Indirect pulp capping in people with Deep Caries Lesion of Primary Teeth, run by Universidade Ibirapuera 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 1 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: finished, as of the sponsor's last update on 11 Jun 2020. 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?

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?

Pulp Vitality (time frame: Up to 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 NCT02903979, which also lists 1 linked publication.

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 11 Jun 2020.
