Impact of Different Restorative Treatments for Deep Caries Lesion in Primary Teeth

June 10, 2020 updated by: Tamara Kerber Tedesco, Universidade Ibirapuera
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%.

Study Overview

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

4 years to 8 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Children will be included that have at least one primary molar with deep cavitated carious lesions in occlusal surface.

Exclusion Criteria:

  • Patients will be excluded with special needs, using orthodontics devices and / or systemic diseases which may affect the oral cavity. Also, teeth with pulp exposure, spontaneous pain, mobility, presence of abscess or fistula next to the tooth, teeth with restorations, sealants or enamel formation defects will also be excluded.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: HVGIC
Restorations with only HVGIC in deep caries lesion of primary teeth.
Other: HVGIC
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.
Active Comparator: Indirect pulp capping
Indirect pulp capping with calcium hydroxide cement, restored with HVGIC:
Other: Indirect pulp capping
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 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
Pulp Vitality
Time Frame: Up to 24 months
To evaluate the survival of different restorative treatments considering the pulp vitality.
Up to 24 months

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
Wong-Baker scale to discomfort
Time Frame: Immediately to restoration procedure.
To evaluate the discomfort of different restorative treatments by a Wong-Baker scale.
Immediately to restoration procedure.
Cost-efficacy analysis by total value of treatment in relation to efficacy
Time Frame: Up to 24 months
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.
Up to 24 months
Restoration longevity
Time Frame: Up to 24 months.
To evaluate the restoration longevity by clinical examination.
Up to 24 months.
Caries progression
Time Frame: Up to 24 months.
To evaluate the caries progression by radiography.
Up to 24 months.
