Evaluation of the Reduced Dentin Etching Time Using Universal Adhesives in the Quality of Cervical Lesions Restorations

Summary

The aim of this study will be to evaluate the effect of reduced dentin etching time on the 6- and 12-months clinical performance of two universal adhesive systems used as etch-and-rinse application mode in non-carious cervical lesions (NCCLs).

Materials \& Methods: 140 restorations will be randomly placed in 35 subjects according to the following groups: SUP5 (Scotchbond Universal Plus adhesive on dentin etched for 5 seconds); SUP15 (Scotchbond Universal Plus adhesive on dentin etched for 15 seconds); GBU5 (Gluma Universal Bond adhesive on dentin etched for 5 seconds); GBU15 (Gluma Universal Bond adhesive on dentin etched for 15 seconds). All groups will be light-cured for 10s/1,000 mW/cm2. A resin composite will be placed by applying three increments and each one will be light cured for 20s/1,000 mW/cm2. The restorations will be finished immediately with fine diamond burs and polishers. The restorations will be evaluated at baseline and after 6- and 12-months by using the FDI criteria. The following outcomes will be evaluated: retention, marginal staining, marginal adaptation, post-operative sensitivity and recurrence of caries. The differences among the groups will be calculated using Friedman repeated measures analysis of variance rank (α = 0.05).
