Resin-modified glass ionomers allow equal or higher fluoride release and there is evidence of higher retention, higher strength and lower solubility. [3] Resin-based glass ionomers have two setting reactions: an acid-base setting and a free-radical polymerisation. The free-radical polymerisation is the predominant mode of setting, as it occurs ...
Resin-modified glass ionomer cement (RMGIC) Pulp capping is a method to protect the pulp chamber if the clinician suspects it may have been exposed by caries or cavity preparation. Indirect pulp caps are indicated for suspected micro-exposures whereas direct pulp caps are place on a visibly exposed pulp.
Both glass ionomer (GI) and resin-modified glass ionomer (RMGIC) have been widely used as a lining or base material for deep cavities where pulp is in close proximity. This is due to their superior properties of good biocompatibility and adhesive nature, providing coronal seal to prevent bacteria infiltration.
Taking into consideration these factors and their respective dental materials' properties, evidence and studies has shown that resin-modified glass ionomer (RMGI) restoration material is the recommended restoration material in clinical situations as it performs optimally - provided aesthetics is not the top priority when restoring these lesions ...
Glass ionomer cement - composite resin spectrum of restorative materials used in dentistry. Towards the GIC end of the spectrum, there is increasing fluoride release and increasing acid-base content; towards the composite resin end of the spectrum, there is increasing light cure percentage and increased flexural strength.

Resin modified glass ionomer was developed to combine the properties of glass ionomer cement with composite technology. It comes in a powder-liquid form. The powder contains fluro-alumino-silicate glass, barium glass (provides radiopacity), potassium persulphate (a redox catalyst to provide resin cure in the dark) and other components such as ...
