Abstract
Fluoride treatment of dentin surface can offer the expectations for the increase of bond strength of carboxylate coments due to the increase of inorganic contents. The purpose of this study was to evaluate the influences of the concentrations
and
the
application time of NaF solutions on the bond strength. Bovine teeth of the lower central incisors were abraded to be exposed to smooth and flat dentin surfaces. Polycarboxylate cements were classified and experimented as a SnF2 contained one and
a
NaF
contained one. The concentrations of 1%, 2%, 3%, 4% and the application time of 2, 5, 8, 10 minutes were used. Total numbers of experimental groups were 32. Shear bond strengths of each groups were measured and used to determine the influences of
concentrations and application time on those measurements. Bond strengths were increased by the higher concentrations of NaF solutions. At the aspect of the application time, groups of 8 minute treatment showed the highest bond strenght. A
polycarboxylate cement containing SnF2 exhibited the higher bond strength than of a NaF contained one.
