The effect of bonding agents on the interfacial bond strength of repaired composites
Dental Materials, 1986Abstract The interfacial bond strengths of repaired samples of 2 macrofilled and 2 microfilled composites were measured using a transverse strength test. Specimens matured for 7 days in 37°C water were ground with 600 grit silicon carbide paper and coated with either an enamel, dentin, porcelain, or acrylic veneer bonding agent or a solvent ...

Clinical status of dentine bonding agents
Journal of Dentistry, 1989Dentine bonding agents are an important clinical contribution to modern composite technology. Important differences exist between the first- and second-generation materials which offer complementary advantages. The second-generation materials offer higher dentine bond strengths at the expense of greater chairside complexity.

Composite Resin Compatibility and Bond Longevity of a Dentin Bonding Agent
Journal of Dental Research, 1985The shear strength of a commercial dentin bonding agent was studied using human dentin in vitro. The agent was tested for compatibility with three proprietary composite resins. In addition, some samples were subjected to prolonged water immersion and thermocycling to determine effects on bond strength.

Microleakage and bond strength of resin restorations with various bonding agents
Dental Materials, 1987Abstract Shear bond strengths and microleakage of 7 dentin adhesives were evaluated by in vitro test procedures. The relative microleakage of the 7 systems was determined in modified Class V cavity preparations having margins in both dentin and enamal.

Enamel‐dentin crown fractures bonded with various bonding agents
Dental Traumatology, 1991Abstract A method is described, by which the fracture strength of bonded, previously fractured incisors can be measured. The study employed incisors from sheep, which could be obtained in suitable numbers and with limited variation in size. The incisors were fractured parallel to the incisal edge.

Bonding Agents and Adhesives: Reactor Response
Advances in Dental Research, 1988Adhesive materials must form multiple bonds with sound tooth substrates for maximum adhesion. Adhesive resins can be applied in incremental layers to bond composite materials to enamel and dentin. Hardening shrinkage and stress concentrations are factors that have detrimental effects on adhesive bonding with resins and composites.

Enamel Conditioning for Orthodontic Bonding with a Single-Step Bonding Agent
Journal of Orofacial Orthopedics/Fortschritte der Kieferorthop�die, 2002In-vitro evaluation of an alternative method to the conventional acid etch technique.240 human anterior and posterior teeth were divided into 16 groups of 15 teeth each. Group variables were: tooth type, enamel conditioning technique (Prompt L-Pop((R)): 3M Espe, Seefeld, Germany, or 37% phosphoric acid and bonding), adhesive (Transbond trade mark XT ...

Bond durability between dentinal bonding agents and tooth structure
The Journal of Prosthetic Dentistry, 1989Glass-ionomer cements and dentinal bonding agents have made possible cavity preparations without mechanical retention. However, durability of bond strength is critical to the longevity of these restorations. This research evaluated the durability of the chemical bond formed by four materials attached directly to tooth structure.

Effect of composite resin bond agent on microleakage and bond strength
The Journal of Prosthetic Dentistry, 1979A study was conducted to evaluate the efficacy of the bonding agents supplied with three composite resins in improving the sealing ability of the materials to tooth structure and the bond of the resins to enamel. When the enamel was not etched prior to insertion of the resin, the use of the bonding agents did not improve marginal seal.

Tensile strength of three bonding agents for resin-bonded prostheses
The Journal of Prosthetic Dentistry, 1989A chemically cured enamel bonding agent and two dentin bonding agents were used in conjunction with a composite resin luting cement to determine whether a difference in bonding strengths would exist when each was subjected to a tensile force.
