Light-Activation Influence On The Thermal Analysis Of A Resin-Modified Glass-Ionomer, Raksha Srinivas
Master's Theses (2009 -)
The acid-base and light polymerization reactions in resin modified glass ionomers (RMGI) have been shown to compete and possibly inhibit one another during early RMGI development. Earlier beginning times of light polymerization initiation may limit the acid-base reaction and if time allowed for the acid-base components to react is increased, the extent of light cure reaction may be lesser. The thermal behavior of a commercially available RMGI was investigated in relation to a light initiation regimen using a differential scanning calorimeter (DSC). The relationship between delay in light initiation or no light initiation and the resultant set matrix of the …
