Lately, flowable compomers are appearing in the market which have similar inferior properties as other flowable composites. Not much literature has been published – Dyract flow; compoglass flow. RESIN MODIFIED / REINFORCED GIC According to Nicholson, “Resin modified GC materials are those that are modified by the inclusion of resin, generally to make them partly photocurable.” As soon as the powder and liquid are combined the acid base reactions begins as usual and continues for many weeks. However, there is a light command available over the top of this reaction which will immediately protect the acid-base reaction from problems of water balance and stabilize the setting cement. According to Christensen (JADA 1997) These materials are termed as “tricure” as it sets by 3 phenomena. i.
