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 be 40 and 60 seconds. The purpose of this study was to know the effect of voltage and time of exp...

... Longer curing time will make surface hardness increased. Previous study Agustantina (2007) reported that the longer the exposure time (20, 40, and 60 second) in all voltage of 200, 210 and 220-volt lead to an increase of resin modified glass ionomer cement's surface hardness. These was due to the long exposure time would result in increased energy light required to activate the initiator for the polymerization process thus the surface hardness will be increasing. ...
