Efectos del termociclado y las cargas cíclicas sobre dos adhesivos dentinarios SB-2 y SBMP: estudio in vitro / Effects of termocycling and cyclic loads over 2 dentin adhesives: SB-2 and SBMP: in vitro study

ABSTRACT

In vitro study was carry out in order to compare the microleakage of two different dentin adhesives SB-2 and SBMP in class V. One hundred class V cavities were designed in the enamel-dentin joint. After restorations they were thermocycled, loaded, stained and sectionated before the microlekage were observed. All the groups showed microleakege. The enamel walls presented better beahvior than roots walls. In roots areas were found significative higher microleakage than enamel walls. Enamel walls of Silux Plus, showed les leakage with SB2, white Z 100 worked better in roots walls with SBMP. Enamel areas of ceramic inlays were less leakage with SB2, and composites restoration always showed better sealed than ceramic inlays with both, SB2 and SBMP
