Objectives: To compare the effectiveness of self-applied fluoride (5000 ppm NaF gel, 1000 ppm SnF2 gel, 226
ppm NaF rinse) and professional-applied fluoride(resin-modified glass ionomer cement; ProSeal) on remineralization of artificial incipient carious lesion on proximal surfaces.
Methods: Two volunteers wore palatal appliances attached with six slabs of artificial proximal lesion, applied
with one of the 4 materials on one side of the appliance comparing to intraoral control on the contralateral side. Every volunteer was randomly assigned to each of the 4 materials. All self-applied fluoride products were applied by the volunteers, while ProSeal was applied by a dentist before their attachment. The fluoride dentifrice was used for 3 minutes twice a day. The palatal appliance was dipped in 20% w/w sucrose solution for 5 minutes, 8 times a day, for 2 weeks of the experimental period. The retrieved slabs were sectioned and lesion areas were examined under polarized light microscope and calculated with Image-Pro plus program.
Results: The fluoride products yielded less lesion area compared to control (p<0.05, paired t-test), in descending
order: NaF rinse, ProSeal, SnF2 gel, and NaF gel; however, there were no statistically significant differences among the first 3 products.
Conclusion: Both self-applied and professional-applied fluoride were effective in reduction of the proximal
carious lesion area, as follows: NaF gel-7.19%, SnF2 gel-21.52%, NaF rinse-23.52%, and ProSeal-21.89%, in addition to 27.85% reduction from the use of fluoride dentifrice alone.
