An in vitro investigation of marginal dentine caries abutting composite resin and glass ionomer cement restorations

An in vitro investigation of marginal dentine caries abutting composite resin and glass ionomer cement restorations.

BACKGROUND There are a number of studies citing the primary reason for replacing auto cure glass ionomer cements was due to recurrent caries. The purpose of this study was to use an in vitro model to measure caries at the dentine restoration interface of bonded composite resin and auto cure glass ionomer cement restorations and to measure the amount of surface degradation occurring in the resto...

Artificial caries in primary and permanent teeth adjacent to composite resin and glass ionomer cement restorations.

18-year survival of posterior composite resin restorations with and without glass ionomer cement as base.

OBJECTIVE Advantages and disadvantages of using intermediate layers underneath resin-composite restorations have been presented under different perspectives. Yet, few long-term clinical studies evaluated the effect of glass-ionomer bases on restoration survival. The present study investigated the influence of glass-ionomer-cement base in survival of posterior composite restorations, compared to...

Comparison of the solubility of three resin cements and a resin-modified glass ionomer cement: An in vitro study

Background and aims: Solubility is an important property of luting cements in determining clinical durability. The aim of this study was to compare the solubility of Panavia, Calibra and Maxcem resin cements with that of GC Fuji PLUS resin modified glass ionomer cement in three different pH values. Materials and Methods: A total of 96 specimens were prepared (8mm diameter, 4mm thickness) accor...

Microleakage Evaluation of Class II Composite Resin Restorations with Different Thicknesses of Resin-Modified Glass Ionomer

Background and Aim: One of the weaknesses of Class II composite resin restorations is gingival microleakage which contributes to postoperative sensitivity and secondary caries. The aim was to evaluate the microleakage in Class II composite resin restorations with different thicknesses of resin-modified glass ionomer (RMGI). Materials and Methods: In this in-vitro study, standardized Class II s...
