Brief Summary

This protocol aims to assess the cost-efficacy and applicability of the treatment of lesions moderate caries using sealants as an alternative to the restorations on occlusal surfaces of deciduous teeth. Initially, a non-inferiority study was designed in order to verify if sealing could be non-inferior than restoration. In this case, it could be preferable since it is less invasive. Therefore, cost will be put forward into the analysis considering even reintervention during the follow-ups (cost-efficacy analyses). Finally, the acceptability could be another differential point between treatments.

Detailed Description

This study aims to evaluate the cost-efficacy and applicability of the treatment of lesions moderate caries using sealants as an alternative to the restorations on occlusal surfaces of deciduous teeth. 96 children aged 3-6 years will be selected. Children must have at least one occlusal surface classified as scores 3 or 4 of International Caries Detection and Assessment System (ICDAS). Children will be randomly allocated according to the treatment: glass ionomer sealant and restoration with glass ionomer. After treatment, teeth will be assessed clinically after 6, 12, 18 and 24 months by trained and blinded examiners regarding the treatment received. The need of reintervention initially treated, either by failures that require repeating of the same procedure or for progression of caries lesions will be considered as primary outcomes. The secondary outcomes will be the chil's acceptability to the treatment.

Primary Outcome Measures
NameTimeMethod
Need of reintervention24 months

Need of reintervention will be considered as all failures after initial treatment that demand repair and/or caries progression associated to the treated lesion at baseline.

After cleaning, It will be analyzed the clinical evaluation of restorations and sealants, will be assessed the presence of caries lesions in dentin and / or evolution of ICDAS scores and if will be necessary other types of treatment, such as endodontics and extraction of teeth included.

Secondary Outcome Measures
NameTimeMethod
Child's reported discomfort1st day

The discomfort will be an outcome collected right after the end of treatment, using Wong baker scale

Duration of treatments1st day

Time spent in interventions will be recorded.
