AIM To test the solubility of dual cure resin modified resin cement in a food simulating solution and the shear bond strength compared to conventional Glass ionomer cement. MATERIALS AND METHOD The materials tested were self-adhesive dual cure resin modified cement and Glass Ionomer (GIC). Twenty Teflon moulds were divided into two groups of tens. The first group was injected and packed with ...

Light cured glass ionomer cements offer improved handling characteristics. Photocuring within the cavity preparation may assist in decreasing the moisture contamination and dehydration difficulties associated with the early stage of setting reaction. The success of restoration depends on good adhesion between glass ionomer cement and the tooth structure. Various dentin conditioners have been ad...

Introduction: Both resin based sealants and glass ionomer cement are widely used for sealing the pit and fi ssures for preventing occlusal caries but the effi cacy of one over the other is not conclusively proven. The dilemma of hidden caries has led to invasively opening of the fi ssure before sealant placement leading to other advantages such as elimination of organic material and plaque, ena...

OBJECTIVE STATEMENT OF PROBLEM Adequate bond strength between glass ionomer cements and composite resin is necessary for the success of the sandwich technique. PURPOSE OF STUDY This study assessed the micro-shear bond strength of composite resin to glass-ionomer cements (GIC) using self-etch adhesives with different pH values. MATERIALS AND METHODS One hundred specimens (6×4×2 mm) were m...

BACKGROUND The aim of this study was to investigate the effect of polyethylene fiber on diametral tensile strength of conventional and resin modified glass ionomer cements. MATERIAL AND METHODS 60 specimens in 6 groups (n=10) were prepared. In group 1 conventional glass ionomer (Fuji GC) and in group 2 resin modified glass ionomer (Fuji LC) were as control groups. In group 3 and 4 conventiona...

BACKGROUND The purpose of this study was to evaluate the effect of dehydration of resin-modified glass ionomer powder/liquid system, resin-modified glass ionomer paste/paste luting cements in three different quantities and to compare them with a conventional glass ionomer luting cement using confocal laser scanning microscope. MATERIALS AND METHODS A conventional glass ionomer (Group I), a re...

statement of problem: despite the wide range of new dental materials, there is still a need for biomaterials demonstrating high biocompatibility, antimicrobial effects and ideal mechanical properties. purpose: the aim of this study was to histologically evaluate the pulpal response to a conventional glass ionomer, a resin modified glass ionomer and a calcium hydroxide in human teeth. materials ...

Background: To date there is not a material considered ideal for the lased dentin. Objective: To compare the bond strength to human lased dentin of self-etch and etch-and-rinse adhesive systems, a self-adhesive resin composite and a glass-ionomer cement. Methods: Forty human molars were sectioned to obtain a 2 mm-thick slab of mid-coronal dentin. The occlusal surface of each slab was polished b...

AIM The objective of this study was to assess the effect of heat application on the mechanical properties of glass ionomer cements. MATERIALS AND METHODS STUDY DESIGN experimental design. The effect of heat on glass ionomer cements during their setting was evaluated by measuring compressive strength, flexural strength and microhardness. Moroever, temperature changes from one surface of the...
