The clinical success of indirect restorations is dependent on multiple factors that include preparation design, mechanical forces, restorative material selection, oral hygiene, and selection of a proper luting agent. The selection of the luting agent is dependent on the specific clinical situation, the type of restoration utilized and the physical, biologic, and handling properties of the lutin...

 This study aimed to investigate the impact of N-vinylcaprolactam (NVC) and Nano-sized yttria-stabilized zirconia (YSZ), separately and simultaneously, on the mechanical properties of the commercial glass ionomer cements (GICs). Methods: The NVC is able to ameliorate the mechanical and surface properties of glass ionomers; however, its effect hasn’t been investigated in conjunc...

objective: zinc oxide eugenol (zoe) under composite restorations should be covered with a suitable material in order to prevent the harmful effect of zoe on the composite. the aim of this in vitro study was to evaluate microleakage of composite restorations in pulpotomized primary molars with different bases for covering the zoe layer and to assess the distance between different layers. materia...

Department of Conservative Dentistry, Yonsei University School of Dentistry and Oral Science Research Center, Seoul, Korea Objectives: The internal adaptation of composite restorations with or without resin modified glass ionomer cement (RMGIC) was analyzed non-destructively using Microcomputed tomography (micro-CT). Materials and Methods: Thirty intact human teeth were used. The specimens were...

objective: removal of enamel superficial layer during microabrasion treatments may adversely affect sealing ability of the restorative materials. the aim of this study was to measure the effect of different periods of enamel microabrasion on the microleakage of class v glass-ionomer restorations. methods: this in vitro experimental study was conducted on 96 class v cavities which had been prepa...

BACKGROUND Glass-ionomer cements perform a protective effect on the dentin-pulp complex considering the F ions release and chemical bonding to the dental structures. On the other hand, those materials have poor physic-mechanical properties in comparison with the restorative resin composite. The main aim of this work was to evaluate the influence of zirconia and/or alumina fillers on the microst...

Glass ionomer cements have been used in pediatric restorative dentistry for 20 years. Their usefulness in pediatric restorative dentistry is preferential relative to other materials because of their fluoride release, chemical adhesion to tooth structure, and availability to use in a variety of clinical scenarios. This paper reviews the use of glass ionomer materials in pediatric restorative den...

BACKGROUND Studies have shown a reduction in bond strength of composites and glass ionomer to bleached enamel and dentin. Several methods have been proposed to reverse compromised bond strength. OBJECTIVE The aim of this study was to evaluate the effect of delayed bonding and application of antioxidant agent on the bond strength of reinforced self-cured (Fuji IX) and light-cured glass ionomer...

Introduction: Full crown preparation may have adverse effects on pulp tissue. In this study, the effect of full-crown preparation on intact versus inflamed pulp tissue was studied. Methods: Fifteen healthy mature cats were randomly selected for this study. The study was performed on four canine teeth of each cat. Cats were anesthetized and then radiographs were taken from the canine teeth. Clas...

statement of problem: in order to increase the performance of glass ionomer cement, it is reinforced with metal powders, short fibers, bioceramics and other materials. fluoroapatite (ca10 (po4 )6 f2 ) is found in dental enamel and is usually used in dental materials due to its good chemical and physical properties. objectives: in this study, the effects of the addition of synthesized fluoroapat...
