NCT02584218

Brief Summary

This study aims to evaluate, through a controlled clinical randomized study, the effectiveness of sealing carious lesions with composite resin in primary molars. For this, healthy children (n=100) with caries lesion reaching to the middle third of the dentin of primary molars, will be submitted to different treatments to remove the lesions. These patients will be randomly allocated in the following treatment groups: (1) cavity sealing (Non-invasive resin based dental sealing) without caries removal; and (2) Partial caries removal and Invasive resin based restoration. The clinical and radiographic success of the treatment groups will be verified by periodic examination of the restorations by USPHS criteria and radiographic subtraction, respectively, which will be checked progression or not of injury. The researcher responsible for these assessments will be blind to the study, whose evaluations will occur after 6, 12, 24 and 36 months of treatment.

Outcome Measures

Primary Outcomes (1)

  • Proportion of radiographic caries progression in the test group in comparison with the control group

    Digital bitewing radiographs were taken at baseline and repeated after 6, 12, 24 and 36-months. The radiographical scoring system that will be used is: 1) Regression in depth of lesion (success) 2: Unchanged depth of lesion (success) 3: Progression in depth of lesion (failure)

    36 months after the intervention

Secondary Outcomes (1)

  • Longevity of resin composite used as sealants to restore dental caries

    36 months after the intervention

Study Arms (2)

Non-invasive resin based caries sealing

EXPERIMENTAL

Application of resin based sealant after acid etching of carious occlusal surface

Procedure: Non-invasive resin based caries sealing

Invasive resin based restoration

ACTIVE COMPARATOR

Application of resin based resin restoration after operative intervention of caries lesion, excavation and preparation on occlusal surface

Procedure: Invasive resin based restoration

Interventions

The dentists use resin based sealants of own choice, and follow their usual clinical procedures based on the instructions from the manufacturer and the guidelines from The Department of Pediatric Dentistry and Orthodontics, Federal University of Rio de Janeiro, Brazil

Also known as: Sealing dental caries
Non-invasive resin based caries sealing

The dentists use preparation design and resin composites of own choice, and follow their usual clinical procedures based on the instructions from the manufacturer and the guidelines from The Department of Pediatric Dentistry and Orthodontics, Federal University of Rio de Janeiro, Brazil
