Resin sealants for occlusal caries lesions: A randomized clinical trial
Objectives: The aim of this randomized controlled trial was to evaluate the longevity and retention of a resin sealant in teeth with occlusal caries lesions involving dentin in comparison to conventional composite resin restorations.
Methods: Sixty-eight teeth from patients aged 10 to 25 years were selected. Inclusion criteria for the lesions were maximum 2 mm opening at occlusal surface and radiographic image showing commitment of up to 2 /3 of dentin. In total 51 permanent molars were treated and followed in the whole period. Twenty-five teeth received resin sealant (Fluroshield; Dentsply, Brazil) and 26 teeth were restored with composite resin (Z350, 3M ESPE - control group). All patients were treated by dental students. Bivariate analysis and survival curves were used to evaluate the results (p <0.05).
Results: After 22 months it was observed that from the 25 teeth sealed, 8 had partial or complete loss of retention, and two teeth had recurrent caries. In the control group no failure was observed, and this group showed greater longevity compared to sealants (p= 0.003). Patients with a higher number of active caries lesions at the time of assessment had higher risk of treatment failure (p = 0.005) and the levels of visible plaque index (p = 0.682) and gingival bleeding index (p = 0.759) were not associated with failures.
Conclusions: It can be concluded that resin sealants showed worse performance compared to composite resin restorations for treatment of caries lesions extending into dentin.
