Efficacy of Sealing Molars: Split-mouth Randomized Clinical Trial

Brazil200 participantsStarted 2017-08-15

Plain-language summary

The sealing of fossae and fissures is an effective procedure in preventing occlusal caries lesions. However, there are gaps regarding its efficacy in the treatment of initial enamel lesions. In addition, there are no studies in the literature that have compared the longevity of sealings performed with the different sealants available in the market. Thus, the objective of this study is to evaluate the efficacy of fossae and fissures sealings performed with a low-cost resinous sealant in occlusal lesions in enamel in permanent and deciduous molars. This is a multicenter clinical study of non-inferiority, randomized, controlled, double blind (patient and operator) with 60 deciduous molars and 340 permanent molars of children 4 and 9 years of age. The sample unit will be the tooth, which will be randomized into two groups using a distributed randomization list in mixed envelopes that will be open only at the time of the procedure. The teeth allocated in the test group will be treated with the sealant preventâ; Those allocated in the control group will employ the Fluroshieldâ sealant. In both groups the procedure will follow the manufacturer's standards. The efficacy of the sealant will be evaluated by means of clinical and radiographic control at 6, 12 and 18 months after the procedure. Secondary outcomes, such as retention, cost, acceptability and quality of life, will also be evaluated.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Children with at least two deciduous and/or permanent molars with occlusal caries lesions scores 1, 2 or 3 of the Icdas (Ismail et al., 2007) will be included, one on each side, preferably from the same arch. Exclusion Criteria: * Patients with special needs; * using orthodontic appliances; * with systemic diseases; * Teeth that present restorations, sealants, formation defects, deep caries lesions that may lead to pulp impairment; * teeth with fistula and/or abscess; * teeth with spontaneous painful symptomatology.

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.
