Effect of aging conditions on the repair bond strength of a microhybrid and a nanohybrid resin composite

J Adhes Dent. 2010 Dec;12(6):451-9. doi: 10.3290/j.jad.a17857. ABSTRACT PURPOSE: this study evaluated the effect of different aging methods on the repair bond strength and failure types of a microhybrid and a nanohybrid composite. MATERIALS AND METHODS: disk-shaped microhybrid (Quadrant Anterior Shine-QA) and nanohybrid (Tetric EvoCeram-TE) resin composite specimens (N = […]

Micro-raman assessment of the ratio of carbon-carbon double bonds of two adhesive systems cured with LED or halogen light-curing units

J Adhes Dent. 2010 Dec;12(6):461-7. doi: 10.3290/j.jad.a17855. ABSTRACT PURPOSE: the purpose of the study was to compare the ratio of carbon-carbon double bonds (RDB) of two adhesive systems cured by five different light-curing units (LCUs) using micro-Raman spectroscopy. materials and methods: ten samples of an etch-and-rinse (Excite), a two-step self-etching […]

Reducing the incompatibility between two-step adhesives and resin composite luting cements

J Adhes Dent. 2010 Oct;12(5):373-9. doi: 10.3290/j.jad.a17854. ABSTRACT PURPOSE: To determine whether the adverse interaction between a two-step/acidic etch-and-rinse adhesive (One-Step Plus [OS], Bisco) and chemically cured resin luting cement [Variolink II, Ivoclar Vivadent] can improve adhesive coupling by reducing the dentin permeability with an oxalate desensitizer (BisBlock, Bisco). MATERIALS […]

Influence of experimental provisional cements containing zeolite, bone hydroxyapatite and linoleic Acid on bond strength of composite to dentin in vitro

J Adhes Dent. 2010 Dec;12(6):469-75. doi: 10.3290/j.jad.a17727. ABSTRACT PURPOSE: to evaluate the dentin bond strength of a composite resin material after the removal of two experimental cements containing zeolite, bone hydroxyapatite and linoleic acid, and one conventional glass-ionomer cement intended as provisional cements. MATERIALS AND METHODS: forty extracted caries-free, erupted […]

In vitro study of the influence of dentin desensitizing and sealing on the shear bond strength of two universal resin cements

J Adhes Dent. 2010 Oct;12(5):381-92. doi: 10.3290/j.jad.a17714. ABSTRACT PURPOSE: To test whether or not dentin desensitizing or sealing methods influence the bond strength of universal resin cements. MATERIALS AND METHODS: The bond strength of two universal resin cements (RelyXUnicem, Self-adhesive Prototype Cement) to human dentin was assessed after different dentin […]

Marginal quality and fracture strength of root-canal treated mandibular molars with overlay restorations after thermocycling and mechanical loading

J Adhes Dent. 2010 Aug;12(4):287-94. doi: 10.3290/j.jad.a17711. ABSTRACT PURPOSE: To evaluate marginal quality, fracture modes, and loads-to-failure of different overlay restorations in rootcanal treated molars in a laboratory setup. MATERIALS AND METHODS: Thirty-two mandibular first molars were randomly assigned to four groups (n = 8): UTR= untreated (control), RCT-COM= root […]

Mechanical testing of indirect composite materials directly applied on implant abutments

J Adhes Dent. 2010 Aug;12(4):311-7. doi: 10.3290/j.jad.a17710. ABSTRACT PURPOSE: To test the strength to failure and fracture mode of three indirect composite materials directly applied onto Ti-6Al-4V implant abutments vs cemented standard porcelain-fused-to-metal (PFM) crowns. MATERIALS AND METHODS: Sixty-four locking taper abutments were randomly allocated to four groups and were […]

Post-etching cleaning and resin/ceramic bonding: microtensile bond strength and EDX analysis

J Adhes Dent. 2010 Aug;12(4):295-303. doi: 10.3290/j.jad.a17709. ABSTRACT PURPOSE: The aim of this study was to evaluate the microtensile bond strength of a resin composite bonded to two heat-pressed ceramics after performing different post-etching cleaning techniques. MATERIALS AND METHODS: Resin composite specimens were bonded to IPS Empress Esthetic (EE) and […]
