Following results were obtained after measuring microhardness value of top and
bottom surface of the specimens, which were made of either light curing glass ionomer
or composite resin, polymerized with visible light and argon laser varying curing time.
1. In Fuji ¥±-LC and Vitremer, significant difference was found in microhardness
value, only in less than 10 seconds of curing time between using of visible light and
argon laser, and in the basis of microhardness value of the bottom surface, curing time
of the argon laser takes only a half than that of visible light.
2. In Prisma, significant difference was found in microhardness value, only in less
than 20 seconds of curing time between using of visible light and argon laser, and in
the basis of microhardness value of the bottom surface, curing time of the argon laser
takes only a half than that of visible light.
3. In Z-100, significant difference was found in microhardness value, only in less than
30 seconds of curing time between using of visible light and argon laser, and curing
time of the argon laser takes only a quater than that of visible light.
4. In Clearfil, significant difference was found in microhardness value, in every each
curing time between using of visible light and argon laser, and curing time of the argon
laser takes only a quarter than that of visible light.
