Review of the fracture toughness approach
Abstract Dental adhesives are usually tested in shear or tension even though neither of these approaches measures the local stress triggering failure. Because the stress level varies extensively over the…
Adhesion to tooth structure: A critical review of “micro” bond strength test methods
Abstract The objective of this paper is to critically review the literature regarding the mechanics, geometry, load application and other testing parameters of “micro” shear and tensile adhesion tests, and…
Dentin bonding—Variables related to the clinical situation and the substrate treatment
Abstract The wetness of dentin surfaces, the presence of pulpal pressure, and the thickness of dentin are extremely important variables during bonding procedures, especially when testing bond strength of adhesive…
Adhesion to tooth structure: A critical review of “macro” test methods
Abstract Objectives Bond strength between adhesive systems and the tooth structure is influenced by a large number of variables, which makes the comparison among studies virtually impossible. Also, failure often…
Variables related to materials and preparing for bond strength testing irrespective of the test protocol
Abstract Introduction Resin bonding can be compared to making a sandwich with the tooth on one side and the restoration on the other, a layer of bonding resin is applied…
A review of adhesion science
Abstract Objective Adhesion or cohesion includes an adherend, adhesive, and intervening interface. Adhesive joints may include one or more interfaces. Adhesion science focuses on understanding the materials properties associated with…
Introduction to and outcomes of the conference on adhesion in dentistry
The Academy of Dental Materials held its annual meeting in Portland, Oregon, USA, on October 29–31, 2009. The full title of the meeting was Adhesion in Dentistry – Analyzing Bond…
Effect of low-elastic modulus liner and base as stress-absorbing layer in composite resin restorations
Abstract Objectives The aim of this study was to evaluate the effectiveness of liner and base materials to reduce the stress resulting from polymerization shrinkage. The null hypothesis tested was…
Bond strength and interfacial characterization of eight low fusing porcelains to cp Ti
Abstract Objectives The aim of this study was the interfacial characterization and the determination of bond strength of commercially available low fusing dental porcelain for Ti. Methods Eight materials were…
Effect of element concentration on nickel release from dental alloys using a novel ion beam method
Abstract Objectives Nickel chromium is widely used as a restorative material in dentistry but its biocompatibility is of concern as there are reports of patients suffering adverse effects caused by…
Relationship between microtensile bond strength and submicron hiatus at the composite–dentin interface using CLSM visualization technique
Abstract Objectives “Submicron hiatus” represents a potential space between the base of the collagenous network and the mineralized dentin when it is acid etched for bonding. This study evaluated the…
Strength of the bond as a predictor of marginal performance: An in vitroevaluation of contemporary adhesives
Abstract Objective The aim of this study was to elucidate whether marginal performance (in terms of % of continuous margins) can, or not, be predicted from μTBS values. A relationship…
Influence of TEGDMA on the mammalian cell cycle in comparison with chemotherapeutic agents
Abstract Objectives The dental resin monomer triethylene glycol dimethacrylate (TEGDMA) caused a cell cycle arrest in response to DNA damage. However, the underlying mechanisms are unclear. Therefore, the influence of…
Does a low-shrinking composite induce less stress at the adhesive interface?
Abstract Objectives Polymerization shrinkage of a composite in a high configuration-factor (C-factor) cavity leads to polymerization shrinkage stress. In the prevention of high polymerization shrinkage stress, a low-shrinking silorane composite…
Polymerization composite shrinkage evaluation with 3D deformation analysis from μCT images
Abstract Objectives The aim of this study was to develop a method to experimentally determine and visualize the direction and amount of polymerization shrinkage. Methods We modified a composite to…
Cyclic loading of notched dental composite specimens
Abstract Objective The purpose of this study was to examine the fracture toughness ( K IC ) of three direct dental composites and one indirect dental composite subject to cyclic…
Crown pull-off test (crown retention test) to evaluate the bonding effectiveness of luting agents
Abstract Objective The purpose of this review was to assess the influencing factors which affect laboratory tests that evaluate the effectiveness of luting agents on the retention of crowns in…
Mechanical strength and subcritical crack growth under wet cyclic loading of glass-infiltrated dental ceramics
Abstract Objectives Evaluate the flexural strength ( σ ) and subcritical crack growth (SCG) under cyclic loading of glass-infiltrated alumina-based (IA, In-Ceram Alumina) and zirconia-reinforced (IZ, In-Ceram Zirconia) ceramics, testing…
Bonding of maxillofacial silicone elastomers to an acrylic substrate
Abstract Objective To investigate the effect of three different primers on shear and peel bond strengths between three maxillofacial silicone elastomers and an acrylic resin after 360 h of accelerated…
One-year stability of resin–dentin bonds created with a hydrophobic ethanol-wet bonding technique
Abstract Dentin bonding performed with hydrophobic resins using ethanol-wet bonding should be less susceptible to degradation but this hypothesis has never been validated. Objectives This in vitro study evaluated stability…
