Shear strength of orthodontic bonding agents
The European Journal of Orthodontics, 1988The aim of this study was to compare the in vitro bond strength to enamel measured in shear of the light-activated bonding agent Heliosit-Orthodontic with the shear bond strength of the two-paste bonding resin Concise and the ‘no-mix’ bonding resin Right-On.

A shear test for the bond strength of ceramometals
The Journal of Prosthetic Dentistry, 1987An innovative shear-testing method was introduced to study the effect of firing temperature, type of metal, and surface texture on the bond strength of the ceramometals. Two common ceramic/metal alloys were used: Olympia, a precious alloy, and Talladium, a base alloy. A Ceramco II Paint-O-Pake opaque was selected for the study. Each porcelain alloy was

Shear bond strength of Scotchbond in vivo
Dental Materials, 1991The shear bond strengths of Scotchbond, HEMA/Scotchbond, and Scotchbond 2 were measured in vivo in dog canine and molar enamel and dentin. Dentin bond strengths were compared in superficial, middle, and deep dentin. The acid-etched enamel bond strengths of the three bonding systems ranged from 10 to 11 MPa and were not statistically different ...

Shear bond strength and microleakage of dentin bonding systems
The Journal of Prosthetic Dentistry, 1991This study evaluated the shear bond strength and microleakage of class V non-retentive restorations with 10 different dentin bonding systems. Some were tested with different composite resins. For the shear bond test, eight specimens were prepared for each product and tested in a universal testing machine. For the microleakage test, 158 V-shaped class V

Shear bond strength of four orthodontic bonding systems
American Journal of Orthodontics and Dentofacial Orthopedics, 1990Recently new orthodontic bonding systems have been developed for attachment of brackets to the etched facial surfaces of teeth. Two of these new systems use bonding agents that contain solvents. It is claimed that this improves the polymerization of the unfilled resin primer and may increase bond strength.

Shear bond strength and microleakage of All-Bond.
American journal of dentistry, 1994The shear bond strengths (SBS) were determined to enamel etched with Uni-Etch (Procedure A) or treated with the mixed Primer A and B (Procedure B), to dentin treated with the Dentin Conditioner (Procedure C) or etched with All-Etch (Procedure D), to amalgam treated with the mixed Dual Opaquer Base and Catalyst which was allowed to self cure (Procedure ...

The shear strength of enamel — composite bonds
Journal of Dentistry, 1977Abstract The shear bond strengths of several commercial materials to etched enamel were evaluated using a modified punch test. An overall significant difference between the bond strength values for the composites was established. Increasing the punch speed was observed to have a detrimental effect on shear bond strength, and investigations into ...

Shear Strength of the Composite Bond to Etched Porcelain
Journal of Dental Research, 1987The shear bond strength of composite resin to porcelain was investigated to optimize variables for bonding porcelain laminate veneers. Scanning electron microscopy was initially used to examine the surface configuration of porcelain prepared under various conditions.

Shear bond strength in porcelain-metal restorations
The Journal of Prosthetic Dentistry, 19801. The push test method showed higher shear bond strength values than the pull test method. 2. A bond strength of 4,500 to 6,000 psi between the dental stone and metal rod was eliminated in a waxed-rod test. Although the strength values were lower in waxed-rod tests, they were believed to be true shear bond strength values. 3.

Dentin shear bond strength of compomers and composites
Dental Materials, 2000The aim of this study was to compare the shear bond strengths and fracture characteristics of two compomers bonded with a single step bonding agent with two modern composites, a microfil and hybrid, bonded with a fourth generation bonding agent.Freshly extracted human third molars were sectioned parallel to the occlusal surface to expose midcoronal ...
