PURPOSE The purpose of this study was to evaluate the interfacial micromorphology of direct esthetic restorations bonded to primary or permanent tooth dentin with a self-etching primer adhesive system. METHODS Superficial dentin at the occlusal surface of 15 primary and 15 permanent molars was exposed with a carbide bur. Prompt-L-Pop was applied in one half of each surface. A control bonding ...

Purpose. The objective of this study was to assess the impact beverages and tooth brushing on microhardness different restorative materials. Materials-methods. Disk-shaped samples compomer (Dyract XP), glass ionomer cement (GIC) (Ionofil Molar AC), composite resin (Filtek Z250) were prepared. randomly allocated four groups conditioned in various (cheery juice, cola, chocolate milk, distilled wa...

The NGCS is based on neuroscience research. While previous gesture classification systems were developed on the basis of gesture observation and their categories were heuristical, the NGCS links the phenomenology to the neurobiology of gestures. The theoretical assumption behind the NGCS is that its main kinetic and functional gesture categories are differentially associated with specific cogni...

The aim of this study was to assess the effect of toothbrushing with toothpastes having different relative dentine abrasivity (RDA) and toothbrushes having different bristles hardness on different composite resins, compomers and traditional glassionomer cements by surface roughness evaluation. All the samples were evaluated regarding the surface roughness using roughness checker (Taylor Hobson-...

This study observed alteration in the radiopacity and microhardness of expired resin-based materials compared to non-expired materials and the operating characteristics of the X-ray source used. Five 2 mm-thick cured specimens were prepared for each material: composite resins (P60®, Z100®), and a compomer (Dyract AP®). Radiopacity of the specimens was evaluated comparing the density of the resi...

Tooth coloured adhesive restorative materials are widely accepted and used for the restoration of carious and non-carious cervical lesions. The aim of this study was to evaluate and compare the solubility and sorption values of compomer (Dyract ®), conventional glass-ionomer(Fuji II ) and resin modified glassionomer (Fuji II LC improved) cements in various beverages such as tea, coffee, coca-co...

The aim of this study was to analyze the diametral tensile strengths of three resin-modified restorative glass ionomer cements--Vitremer, Fuji II LC and Photac Fil and one compomer--Dyract. They were tested at 1 hour, 1 day and 1 week. Kratos testing machine was used to load the specimens at a cross-head speed of 0.5 mm/min. The data were analyzed by two-way ANOVA and Tukey's test that showed s...
