Clinical Evaluation of Glass Ionomer Cement as an Adhesive for the Bonding of Orthodontic Brackets
Glass ionomer cement has been shown in previous studies to retard decalcification and caries formation. This cement would be valuable in orthodontics if it proved to have adequate adhesive properties. Therefore, this study was designed to determine if there is a significant difference in the …

Evaluation of the Tensile Bond Strength of Orthodontic Bracket Bases Using Glass Ionomer Cement as an Adhesive
… oral environment has led to experimentation with glass ionomer cements. This study compared the tensile bond strength of eight different orthodontic bracket base designs in vitro and assessed the amount of adhesive remaining on the bracket pad after debonding. Each bracket base design included in …

Oberflächeneigenschaften von Zahnrestaurationsmaterialien
… restorative materials (amalgam, gold, composite, glass ionomer cement, ormocer and compomer). The influence increasing roughness on the surface free energy and the distribution into dispers and polar portions was determined. Metals exhibited lowest values (gold alloy and amalgam). The surface free …

Ionic exchanges between glass ionomers and demineralised dentine
Glass-ionomer cement has been used in the Atraumatic Restorative Technique (ART) for stabilisation of carious lesions. The infected layer or fully demineralised dentine is removed by dental hand instruments only and glass-ionomer cement is placed to restore the lesion leaving the affected layer or …

Investigation of Silver Enhanced Dental Restorative Materials by the Development of an In Vitro Oral Biofilm Model
… formulations that have been combined with glass ionomer cement. Three out of nine bacterial species considered to be early colonisers (Streptococcus oralis, Streptococcus mutans, & Neisseria subflava) were inoculated at 0.1 OD600 into wells containing sterile glass-ionomer disks. The …

Evaluation of Shear Bond Strength of Two Resin-Modified Glass-Ionomer Cements
… a new paste-paste formulation of resin-modified glass-ionomer cement (Rm-GIC) to an exising powder-liquid formulation. The study will test the hypothesis that the new paste-paste formulation of Rm-GIC (Fuji-Cem ™, GC Corp, Tokyo, Japan) has the same bond strength as an existing popular …

V- Shaped Defects – Epidemiology, Clinical Picture and Obturation Opportunities // Клиновидни дефекти – епидемиология, клинична картина и възможности за обтуриране
… the application of three types of materials - glass-ionomer cement, liquid, and universal photo composites - has been investigated through experimentation and simulation analysis. The universal nanohybrid photo composite is most suitable for v-shaped defects. It exhibits the lowest …

Effects of tooth quality, tooth structure, and cement mixing ratios on dental adhesion
… conditions was evaluated using a commercial glass-ionomer cement. The same procedure has been repeated on unground and ground teeth by changing several different cement mixing ratio. The chemical, thermal, and mechanical properties of the cement mixing ratios were evaluated separately to …

Optical characterisation of the interaction between calcium-silicate based dental restorative materials and dentine
… to dentistry, calcium silicate based cements have been mainly used for endodontic applications, principally due to their long setting time. Recently, a new formulation of this cement was produced as a coronal restorative material. The aim of this project was to study the nature and …

The mechanical and other properties of ionomer cements
Ionomer cements, a novel composite material, are formed at ambient temperatures by mixing an aqueous polyacid with an ion-leachable powder. The glass ionomer cement known as ASPA, a dental restorative material, produces strong and hydrolytically stable cements. Applications of this material outside …
