Glass ionomer cements show great potential as low cost, minimally invasive dental restorative materials. However, their use is limited by relatively poor mechanical properties, especially fracture toughness. One possibility for improving their fracture toughness is through the addition of fluorhydroxyapatite nanoparticles, which resemble the crystals found in tooth enamel. Hydroxyapatite and fl...

The purpose of this study was to compare regional bond strength at middle and cervical thirds of the root canal among glass fiber-reinforced composite (FRC) endodontic posts luted with different cements, using the push-out test. To compare the performance (retention) of two types of luting cements polycarboxylat cement and Glass ionomer cement used to cement translucent fibre post. and To compa...

The purpose of this study was to evaluate and compare the retention strength of five cement types commonly used in implant-retained fixed partial dentures, before and after compressive cyclic loading. In five solid abutments screwed to 5 implant analogs, 50 metal Cr-Ni alloy copings were cemented with five luting agents: resin-modified glass ionomer (RmGI), resin composite (RC), glass ionomer (...

This study investigated the effects of the cement type and the water storage time on the push-out bond strength of a glass fiber post. Glass fiber posts (Fibrekor, Jeneric Pentron) were luted to post spaces using a self-cured resin cement (C&B Cement [CB]), a glass ionomer cement (Ketac Cem [KC]) or a resin-modified glass ionomer cement (GC FujiCEM [FC]) according to the manufacturers' instruct...

Introduction: Glass ionomer and polycarboxylate cement have different effects on the marginal seal, microleakage, pulp tissue stimulation, and gingival health. The purpose of this study was to assess the effect of these cement on the gingival health of primary molars restored with stainless steel crowns (SSC). Methods: A total number of 34 children were selecte...

AIM To evaluate the physical and mechanical properties of two cements with a similar chemical composition to mineral trioxide aggregate and to attempt to improve their properties by producing a composite material. METHODOLOGY Two cement types were used: a mixture of calcium sulpho-aluminate cement and Portland cement (CSA) and calcium fluoro-aluminate cement (CFA) in conjunction with an admix...

BACKGROUND The selection of the appropriate luting cement is a key factor for achieving a strong bond between prepared teeth and dental restorations. AIM To evaluate the shear bond strength of Zinc phosphate cement Elite, glass ionomer cement Fuji I, resin-modified glass ionomer cement Fuji Plus and resin luting cement Panavia-F to Turkom-Cera all-ceramic material. MATERIALS AND METHODS Tur...

Magnetic resonance micro-imaging was applied to study water diffusion into resin-modified glass ionomer cement restoration and to evaluate the effect of surface coating over restoration. Two cavities were prepared on the labial surface of extracted teeth and restored with resin-modified glass ionomer cement; one was protected with surface coating and the other was not. Immediately after restora...

OBJECTIVE To estimate the microhardness of glass ionomer cement (vitrofil) and resin modified glass ionomer cement (vitremere) in the presence and absence of different surface protections. STUDY DESIGN An in-vitro experimental study. PLACE AND DURATION OF STUDY The Department of Operative Dentistry, Dr. Ishrat-ul-Ebad Khan Institute of Oral Health Sciences, Dow University of Health Sciences...
