The main purpose of this study was to evaluate the anticariogenic effect of argon
laser. Histological observations on lesion initiation and progression were performed under
the polarized microscope. The results from the present study can be summarized as
follows ;
1. The specimens of laser cured group were shown to have more irregular and
discontinuous lesion body in general than visible light cured group with rather
continuous positive birefringence.
2. With lesion initiation and progressions, almost all the specimens showed deeper body
of lesion with shallower intact surface zone in the visible light cured group than the
laser cured group(p<0.05). When the comparison was made between the two argon laser
cured groups, the single-cure group showed deeper lesion body and the shallower
surface layer than double-cure group.
3. Based upon the above mentioned results of this study, it can be assumed that the
use of argon laser in the procedure of resin polymerization may provide the child and
adolescent patient population with anticariogenic effect as well as efficient
polymerization. Further studies using various materials and experimental conditions are
being encouraged.
