Microleakage of Seven Dentin Bonding Agents

Journal of Esthetic and Restorative Dentistry, 1990
The purpose of this study was to evaluate the ability of seven dentin bonding agents to reduce dye penetration at the margins of microfill composite restorations in dentinal cavities.Forty extracted molars were selected and cleaned. Cavity preparations were made in dentin with #55 carbide burs.

Effect of Whitening Agents on Dentin Bonding

Journal of Esthetic and Restorative Dentistry, 2000
ABSTRACT Background: Several studies have shown a reduction in enamel bond strengths when the bonding procedure is carried out immediately after vital bleaching with peroxides. This reduction in bond strengths has become a concern in cosmetic dentistry with the introduction of new “in‐office” and “waiting‐room” bleaching techniques.

Mutagenic activity of various dentine bonding agents

Biomaterials, 1996
The potential mutagenicity of bonding agents of the new generation was characterised by employing an in vitro gene mutation assay. Eight different components of three dentine bonding systems (Scotchbond Multi Purpose, Prisma Universal Bond 3 and C&B Metabond) were tested in the Ames test using four different Salmonella strains (TA97a, TA98, TA100 and ...

Film thickness of various dentine bonding agents

Journal of Oral Rehabilitation, 1997
summary Curing dentine bonding agents create a film thickness on the surface of teeth which are prepared for all‐ceramic crowns. The aim of this study was to investigate if the film thickness of dentine bonding agents (DBAs) is acceptable with the fit of definitive restorations of 50–100 μ. AllBond 2®, Syntac®, ART Bond®, P‐Bond® (an experimental

Clinical status of dentine bonding agents

Journal of Dentistry, 1989
Dentine 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.

Clinical evaluation of three dentine bonding agents

Australian Dental Journal, 1989
AbstractThree commercial dentine bonding agents were used with composite resin to restore non‐undercut Class V abrasion lesions without enamel etching. Patients were reviewed at 3, 6 and 12 months and the integrity and marginal staining of restorations was assessed.The loss incidence of restorations ranged from 18 to 40 per cent at one year, and there ...

RE‐WETTING AGENTS FOR DENTIN BONDING

Journal of Esthetic and Restorative Dentistry, 2001
Adhesive restorations have been increasingly used in restorative dentistry primarily because of their potential to generate sealed interfaces and to allow for conservative preparation designs. Adhesive restorative techniques demand a close interaction, either chemical or micro‐mechanical, between the tooth substrate (enamel and dentin) and the adhesive

The characteristics and performance of dentine bonding agents

Clinical Materials, 1993
Several attempts have been made to synthesise dentine bonding systems, but low bonding strength, increased variance, toxicity and poor hydrolytic stability were some of the disadvantages excluding them from being widely approved. However, many dentine bonding systems are considered to be biocompatible and have become commercially available.

Third Generation Dentin Bonding Agents: A Microleakage Study

Journal of Esthetic and Restorative Dentistry, 1990
This article examines and compares the extent of microleakage after 24 hours in freshly extracted teeth using three newer or “third generation” dentin bonding agents. Gluma/Pekalux and Scotchbond 2/Silux were more effective in preventing microleakage in cementum/dentin margins than was Universal Bond/Prisma Micro‐fine.

Bond strengths of dentine bonding agents to dentine

British Dental Journal, 1992
This study assessed comparatively the tensile bond strengths to dentine of four resin dentine bonding agents. Flat surfaces were produced in the occlusal dentine of human third molars, finished with 600-grit paper and prepared for bonding to Silux Plus composite with Gluma, Prisma Universal Bond 2, Scotchbond 2 and Tenure.
