OBJECTIVES To evaluate the microtensile bond strength of total-etch or self-etch adhesives to caries-affected versus normal dentine, and to correlate these bond strengths with DIAGNOdent laser fluorescence and Knoop microhardness (KH) measurements of the substrates. METHODS Extracted carious human molars were ground to expose flat surfaces where the caries lesion was surrounded by normal dent...

The oxide etch rate of plasma etch tools is estimated from plasma impedance monitoring data. Linear statistical modelling and stepwise regression are used to generate predictions of the mean and range oxide etch rate. The relationship of the mean etch rate to yield is explored for one processing step. Potentials for advanced process control of the etch tools are presented.

objective: a clinical challenge of using zirconia frameworks is to achieve adequate bond with different substrates. this study aimed to evaluate the effect of bioglass and silica coating of zirconia substrates on microshear bond strength of resin cement to tetragonal zirconia. methods: this laboratory experimental study was conducted on zirconia discs. a total of 120 ytzp zirconia (zirkonzahn) ...

Aim: To assess the influence of two adhesive systems on the bond strength of the restorative material to enamel and dentin after bleaching. Materials and method: 60 non-carious extracted premolar teeth after bleaching with 40% Hydrogen peroxide were divided into four groups based on type of adhesive system used and the tooth surface i.e. enamel and dentin used for bonding. G1ET and G3DT were re...

OBJECTIVES Several adhesive systems are available for cementation of fibre posts into the root canal. The aim of the present study was to investigate the push-out bond strengths of quartz fibre posts to root dentin with the use of different total-etch and self-adhesive resin cements. STUDY DESIGN Ninety single-rooted human premolars were endodontically treated and standardized post-spaces wer...

The aim of this study was to compare two self-etching and a total-etch adhesive systems by assessing their shear bond strength to bovine enamel and the microleakage on class V composite restorations prepared on bovine enamel. Bovine teeth selected and allocated in three groups: Group 1: Scothbond Multi-Purpose; Group 2: Clearfil Liner Bond 2V; Group 3: Etch & Prime 3.0. For the microleakage tes...

Background: To evaluate the clinical performance of universal adhesives in etch-and-rinse or self-etch application modes through meta-analysis.

This paper describes the development of dentin bonding systems, and describes the current strategies for bonding composite resin materials to dentin. Two main strategies are available--total-etch or self-etch--and each has unique advantages and disadvantages. For each category, simplified systems that reduce the number of application steps are available. Currently, the market is moving towards ...
