OBJECTIVE To compare the effectiveness of annual topical application of silver diamine fluoride (SDF) solution, semi-annual topical application of SDF solution, and annual application of a flowable high fluoride-releasing glass ionomer in arresting active dentine caries in primary teeth. METHODS A total of 212 children, aged 3-4 years, were randomly allocated to one of three groups for treatm...

The sulfonated polyphenylene ionomer, SPP-QP, being used as the anode binder, improves durability of polymer electrolyte fuel cells in gas exchange cycle test simulating start-up conditions.

backgrounds the degree of microleakage is one of the main criteria in evaluating the restorative materials such as glass ionomer (gi) restoratives, which are available in two forms: loose powder and liquid form to be hand-mixed or pre-proportioned in a capsule to be mixed mechanically. objectives this study was conducted to compare the microleakage of encapsulated gi restoratives with their han...

With the aim of assessing the performance of Brazilian and imported glass ionomer cements (GIC) with regard to microleakage, 40 primary molars received two standard class II cavity preparations with margins in enamel. Twenty cavities were filled with Brazilian materials (Vidrion R and Vidrion R(Caps)) and the other 20 cavities were filled with imported materials (Fuji IX and Fuji IX(GPFast) cap...

OBJECTIVES This study evaluated the influence of water on the volumetric dimensional change of six direct placement core build-up materials by using Archimedes' principle. METHODS The effect on dimensional change due to the setting reaction was determined through the use of a silicone oil storage medium. The materials used were two dual-cured resin composites (CoreStore and Build-It FR), two ...

OBJECTIVES To investigate the influence of glass ionomer cement layers with various thickness and cement contamination on the fracture resistance of thin zirconia plates luted onto coplanar human molars. MATERIALS AND METHODS Zirconia plates measuring 0.7 mm in thickness were luted onto 70 coplanarly trimmed human molars with glass ionomer cement. Cement layers measuring 100, 250, 1000, and 2...
