چکیده

Light-cured adhesive systems have been widely used in dental clinical practice. Bonding to dentin remains poorly understood and unreliable. Previous studies have shown that quality of hybrid layer (HL: interface between adhesive layer and dentin) is very important to the reliability of whole bonding. Raman spectroscopic studies of the adhesive distribution in HL indicate that monomers do not completely infiltrate into etched dentin, thereby contributing to early failure of whole bonding.

Promotion of adhesive penetration and resin bond strength to dentin using non-thermal atmospheric pressure plasma.

Non-thermal atmospheric pressure plasmas (NT-APPs) have been shown to improve the bond strength of resin composites to demineralized dentin surfaces. Based on a wet-bonding philosophy, it is believed that a rewetting procedure is necessary after treatment with NT-APP because of its air-drying effect. This study investigated the effect of 'plasma-drying' on the bond strength of an etch-and-rinse...

Microhardness evaluations of resin-dentin bonding areas by nano-indentation.

The purpose of this experiment was to determine the hardness values of the hybrid layer and its surroundings through the continuous use of a microhardness measuring device. Black's Class V cavities were prepared in nine dog teeth. The cavities were divided into four groups according to the dentin adhesive system applied. The adhesive systems were: "Bond One System", "Liner Bond II sigma System"...

Statement of Problem: The quantity of remaining unreacted double bonds may be a significant factor pertaining to the mechanical, physical and chemical properties of restorative resins. Insufficient polymerisation within the hybrid layer may cause significant differences in the quality of this layer, and act as a reservoir for monomer release thus increasing cytotoxic potential. Purpose: The aim...

Evaluation of Different Dentin Adhesive Systems and its Effect on Apical Microleakage: An In Vitro Study

BACKGROUND Regardless of the technique and the material used, the goal of obturation remained the same that is to seal every portal of exit in the root canal system. It's not only the apical openings that need to be sealed but also lateral openings, coronal access opening and perforations if they exist failure of the adhesive root canal sealer has led to the idea of usage of dentin bonding agen...
