Influence of Surface Sealants on the Quality of Posterior Restorations With Bulk Fill Composites
Sponsor: Universidade Federal Fluminense
Summary
Treatment clinical trial, randomized, controled, parallel, double-blinded, with three groups, that aims to evaluate if there is some advantage in applying surface sealants (Biscover, Bisco, USA or Permaseal, Ultradent, USA) associated with a Bulk Fill Composite (Tetric N-Ceram Bulk Fill, Ivoclar Vivadent,Liechtenstein). Volunteers will be selected and recruited,following inclusion criteria and pre-established exclusion. All volunteers will be informed and sign a term of clarification and consent. 53 enrolled patients will receive 159 Class I or Class II dental restorations, made in three different ways, one from each experimental group (no sealant, or one of the evaluated surface sealants). Occlusal or Proximo-occlusal lesions will receive the selected treatments separated by groups. Group Bulk without surface sealant (BNS), Group Bulk and Biscover (BSB), and Group Bulk and Permaseal (BSP). Immediate post-operative tooth sensitivity will be evaluated after one week. Restorations will be evaluated every 6 months for pain assessment, shape, fractures, staining or recurrent caries, using scores. To determine in which group each tooth will be enrolled, the authors will randomize the teeth.

Interventions
Bulk without surface sealant
Adhese SE self-etch adhesive system will be applied according to the manufacturer's instructions in 53 teeth.Then, the Tetric N-Ceram Bulk fill composite will be used in increments of no more than 4 mm, using the bulk restoration technique, and each increment will be photoactivated for 40 seconds.
Bulk with Biscover
Adhese SE self-etch adhesive system will be applied according to the manufacturer's instructions in 53 teeth.Then, the Tetric N-Ceram Bulk fill composite will be used in increments of no more than 4 mm, using the bulk restoration technique, and each increment will be photoactivated for 40 seconds. After the restoration is completed, biscover surface sealant will be applied according to the manufacturer's instructions.
Bulk with Permaseal
Adhese SE self-etch adhesive system will be applied according to the manufacturer's instructions in 53 teeth.Then, the Tetric N-Ceram Bulk fill composite will be used in increments of no more than 4 mm, using the bulk restoration technique, and each increment will be photoactivated for 40 seconds. After the restoration is completed, Permaseal surface sealant will be applied according to the manufacturer's instructions.
