Medium‐term evaluation of the bond strength and dentin penetration of self‐adhesive resin cements to root dentin

Background Medium‐term evaluate the bond strength and tag formation in root dentin using self‐adhesive cements Maxcem Elite (MCE), Relyx U200 (RU2), SeT PP (SPP) and Megalink (MGL) compared to conventional cement Relyx ARC (ARC) for glass fibre post cementation. Materials and methods One hundred bov...

Zusammenfassung:Background Medium‐term evaluate the bond strength and tag formation in root dentin using self‐adhesive cements Maxcem Elite (MCE), Relyx U200 (RU2), SeT PP (SPP) and Megalink (MGL) compared to conventional cement Relyx ARC (ARC) for glass fibre post cementation. Materials and methods One hundred bovine incisors roots were endodontically treated and divided into 5 groups (n = 20) according to the cementation system: MCE, RU2, SPP, MGL and ARC. All cementation systems were evaluated at 24 h (1) and 12 months (2) after post cementation. Specimens from the cervical, middle and apical thirds of the root were submitted to push‐out bond strength test and confocal laser microscopy to verify the dentin penetration. The adhesive failure mode was classified as adhesive, cohesive and mixed. Data were analysed by one‐way ANOVA and Tukey tests (α = 5%). Results ARC‐1 and ARC‐12 showed the highest bond strength (P
