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

Brazil108 participantsStarted 2016-11

Plain-language summary

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%.

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
