Topical fluoride application for children is a widely performed procedure in the field of
Pediatric Dentistry for its dental caries prevention effects. However, it is recently
recognized as having some unwanted effects on several esthetic restorative materials as
it roughens the surfaces of the restorative materials. In order to evaluate the surface
changes in esthetic restorative materials, the author immersed composite resin, glass
ionomer cement, and resin-modified glass ionomer cement specimens in various topical
fluoride agents and measured the weight loss and also, examined the specimens under
the scanning electron microscope.
The followings are the results :
1. All the specimens immersed in APF gel for 4 minutes showed statistically
significant weight loss.(paired t-test, P<0.05).
2. There was no statistically significant weight loss for the resin-modified glass
ionomer cement and composite resin groups immersed in sodium fluoride solution(paired
t-test, P>0.05).
3. When the glass ionomer cement group was immersed in APF gel for 1 and 4
minutes, there was a statistically significant weight loss compare to other esthetic
restorative materials(ANOVA, P>0.05).
4. In the resin-modified glass ionomer cement group and the composite resin group,
weight loss in the APF gel 4 minutes immersion group was greater than the 1 minute
immersion group, and it was statistically significant(ANOVA, P<0.05).
5. When the specimens were examined under scanning electron microscope, the surface
changes were greater in the order of glass ionomer cement, resin-modified glass
ionomer cement, composite resin and also in the order of APF gel 4 minute immersion
group, 1 minute immersion group, sodium fluoride immersion group, and control group.
