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...

OBJECTIVE Glass carbomer cement represents a new generation of dental material, which mineralizes gradually into fluorapatite. The aim of this study was to evaluate the microleakage and marginal integrity of newly developed glass carbomer cement with and without protective surface coating (SC) in primary molars. METHODS Standardized cavities were prepared on extracted human primary molars, an...

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...

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...

Replacement of a restoration leads to excessive cutting of the otherwise healthy tooth structure which affects the integrity of teeth. Repairing existing glass ionomer restorations may appear to be a good alternative to complete replacement of the restoration which presents no evidence of failure on clinical exam. The objectives of the study were to determine the proportion of faculty advocatin...

Objective: To evaluate the influence of type cement on fracture resistance full-contour resin nanoceramic crowns cemented over preparations with knife-edge margins. Methods: A right lower premolar typodont model was prepared a 1.5-mm axial reduction, 2.0-mm occlusal and vertical margin. An anatomical crown designed from digital scanning preparation using CAD/CAM software. Then, 20 were milled b...

 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...

With the addition of fixed appliances, the risk of demineralization can only be compounded, as the presence of brackets, archwires, ligatures, and other orthodontic devices make maintaining proper oral hygiene even more difficult, leading to plaque accumulation and ultimately demineralization around brackets in as little as 4 weeks time. The prevalence of new enamel lesions among orthodontic pa...

AIM The aim of this study was to evaluate the three-body wear-resistance of one type of restorative glass-ionomer cement (GIC). MATERIALS AND METHODS Specimen including conventional GIC (Ionofil Molar AC Quick: IMACQ), hybrid ionomer (Fuji II LC), and composite resin (Heliomolar) were tested in a wearing machine. In this machine, a 6 kg load was applied via pressable chromium-cobalt bar at 5,...

Poly(N-isopropylacrylamide-co-acrylic acid) (PNIPAM-co-AA) ionomer chains can form stable nanoparticles in water at temperatures higher than their lower critical solution-temperature. A combination of the weight average molar mass (Mw) from the absolute average scattering intensity and the hydrodynamic radius distribution (f(Rh)) from the line width distribution G(Γ) was used to study the influ...
