AIM To evaluate and compare the sorption, solubility, and compressive strength of three different glass ionomer cements in artificial saliva - type IX glass ionomer cement, silver-reinforced glass ionomer cement, and zirconia-reinforced glass ionomer cement, so as to determine the material of choice for stress-bearing areas. MATERIALS AND METHODS A total of 90 cylindrical specimens (4 mm diam...

Ultrasonic scaling of class V composite or glass Ionomer restorations may cause destructive effects. The purpose of this study is to investigate the effects of ultrasonic scaling on the marginal leakage of composite and Glass Ionomer restorations. An in-vitro study was performed on thirty- two upper and lower premolar teeth, free of any kind of caries, cracks or facets. Class V cavities, with t...

The detection of ground-glass opacity (GGO) is increasingly common. Sufficient data have been accumulated to formulate recommendations for observation, intervention, and treatment modalities. However, an understanding of many nuances and uncertainties in the available data is needed to avoid making management errors. This article discusses the range of possible entities, risk factors and charac...

This study evaluated the effect of primer on shear bond strength and marginal gaps of six new compomers immediately after light-activation. A resin-modified glass ionomer cement, a conventional glass-ionomer cement and a microfilled composite were used for comparison. The marginal gap widths of each of the four compomers and a microfilled composite used with the primer were significantly smalle...

The purposes of this in vivo study were to determine if placing a sealant over a glass ionomer restoration modifies its fluoride release, and to examine the effect on glass ionomer of a 4-min application of topical fluoride. Fluoride release from glass ionomer preventive resin restorations placed in 21 bovine teeth was measured before and after removing their sealants. Fuji II, Ketac Silver, an...

This study compared the flexural strengths and bond strengths to dentin and enamel of two brands of silver-reinforced glass ionomers with their respective unfilled glass-ionomer cements for luting. The results led to the following conclusions. 1. No significant differences in bond strengths to tooth substrates were recorded between silver-reinforced and unfilled glass ionomers. 2. Although the ...

Glass ionomer cements (GICs) are widely used in restorative dentistry.1 In dentistry, one of their advantages over other restorative materials is that they can be placed into tooth cavities without an additional bonding agent.2 They also possess a fluoride-releasing property3 and are relatively biocompatible with the pulp.1 Adhesive property and fluoride release of glass ionomer cement contribu...

AIM The purpose of the present study was to determine the influence of glass ionomer cement and amalgam restoration on the level of Streptococcus mutans in the interproximal plaque at periodic intervals and also to compare these values. MATERIALS AND METHODS Seventeen adult patients having two proximal carious lesions on any quadrant of the jaw (either opposing or contralateral) were selected...

The number of publications reporting on the survival of ART sealants and ART restorations has increased considerably in recent years. A systematic investigation of their longevity is therefore warranted. Based on three exclusion criteria, a literature search in the electronic libraries Pubmed and Medline revealed 28 eligible publications for inclusion in a meta-analysis. High mean survival rate...
