OBJECTIVE The aim of the present clinical longitudinal study was to observe, over 10 years, the prognosis of abutment teeth restored with fixed prostheses retained by glass ionomer luting cements and one conventional zinc phosphate cement. METHODS Three dentists prepared 135 abutment teeth in 61 patients to retain 81 fixed prostheses. The prostheses were retained by two glass ionomer luting c...

OBJECTIVES This in vitro study evaluated the effect on interfacial gap-formation around resin-modified glass-ionomer (RMGIC) root surface restorations with (a) variations in powder/liquid ratio (P/L) of the first increment of an incremental procedure, compared with a bulk restoration technique, and (b) delayed versus immediate polishing, to permit maturation. METHODS Cavity preparations were ...

conclusions fuji plus cement exhibited better sealing ability in closed and open margins compared to g-cem and fleck cements. when using g-cem and fleck cements for full metal ceramic restorations, clinicians should try to minimize marginal gaps in order to reduce restoration failure. in situations where there are doubts about perfect marginal adaptation, the use of fuji plus cement may be help...

Aim: The aim of the study was to evaluate the surface conditioned dentin and its effect on microleakage of metal copings luted with glass-ionomer cement. Objectives: (1) To evaluate the morphology of unconditioned and conditioned dentin, (2) to evaluate the elemental composition of unconditioned and conditioned dentin, (3) to evaluate and compare the microleakage of metal copings luted with gla...

Seventy-one caries-free human occlusal fissures were used for this study. Twenty-two fissures were sealed with a glass ionomer sealant (Fuji Ionomer Type III--G-C Dental Industrial Corp., Tokyo, Japan), 24 were widened with a diamond bur and sealed with the glass ionomer sealant, and 25 were left unsealed. After one week, the sealants were removed as completely as possible with a probe. All fis...

Background. Acid etching prior to orthodontic bracket bonding may result in enamel wear or cracks following bracket removal. The manufacturer of Fuji Ortho LC glass-ionomer (GI) claims that it can bond brackets to wet unetched enamel. This study aimed to compare the bracket bond strength to etched and unetched enamel under dry and wet conditions. Methods. In this in vitro study, 60 intact premo...

PURPOSE To quantify the internal free surface in various resin cements and glass-ionomer-based materials. MATERIALS AND METHODS Materials tested were Nexus fluid (NXF) and viscous (NXV), Vitremer (VTM), Fuji II LC (FII), Vitremer Luting Cement (VLC), Dyract (DYR) and Compoglass (COM). Samples (n=5) were made of each material between two microscopic glass slides under same weight. With a trans...

Objectives: This study was conducted to investigate marginal adaptation, compressive strength, water sorption, solubility, fluoride and calcium release of a claimed bioactive restorative material (ACTIVA BioACTIVE Restorative) compared glass ionomer (Fuji IX) resin composite (SphereTEC). Materials methods: ACTIVA evaluated relative Fuji IX SphereTEC one. Marginal gap width detected via scanning...

Objective: The purpose of this study was to evaluate the effects of application of three over the counter whitening toothpastes (Colgate Optic White, Aquafresh Ultimate White and Crest 3D White) on the color stability of different esthetic restorative materials (Resin composite/Filtek Z250 XT, resin modified glass ionomer/GC Fuji II LC, and glass ionomer/Ketac Molar Quick Aplicapweek) commonly ...

OBJECTIVES To evaluate microleakage and marginal gaps in full cast crown restorations bonded with six different types of cementing agents. METHODS Sixty non-carious human premolars and molars were prepared in a standardized manner for full cast crown restorations. The mesial and distal margins were located in dentin, while the vestibular and palatal/lingual margins were located in enamel. Cro...
