Açaí juice stains a glazed resin-modified glass-ionomer cement

Acta Odontológica Latinoamericana
Coloured compounds (anthocyanins) in açaí can stain resin-modified glass-ionomer cement (RMGIC) due to its low staining resistance. Aim: The aim of this study was to assess whether açaí compromises the surface colour and roughness of RMGIC in vitro. Materials and Method: Disc-shaped specimens (2 mm thick, 8 mm in diameter) of VitremerTM (3M ESPE, St ...

Modifications in Glass Ionomer Cements: Nano-Sized Fillers and Bioactive Nanoceramics. [PDF]

, 2016
Glass ionomer cements (GICs) are being used for a wide range of applications in dentistry. In order to overcome the poor mechanical properties of glass ionomers, several modifications have been introduced to the conventional GICs. Nanotechnology involves

The effect of voltage and time of exposure on surface hardness of resin modified glass ionomer cement

Dental Journal, 2007
Light intensity can affect the polymerization of resin-based material therefore it will also affect surface hardness. To compensate reduction of light intensity becaused of the input of low voltage (200 and 210 volt), the exposure time was prolonged to ...
