Abstract
Decalcification of enamel is a significnat clinical liability during orthodontic treatment with fixed appliances. Fluoride-releasing resin adhesives are sued to solve this problem but its bond strength and the amount of fluoride released have not
been
fully evaluated yet. and the interest in glass ionomer cement is growing as an adhesive releasing fluoride. But previous studies have indicated that lining glass ionomer cements have low bond strength. Thus, the shear tensile bond strength after
24
hours and after thermocycling and the amount of fluoride released for 40 days of experimental grous were evaluated and compared with those fo the control group in this study. No-mix type resin adhesive (Mono-Lok 2) was used as a control, and
resin
cement with sealant releasing fluoride (Phase II), fluoride-releasing light cured resin cement (Orthodontic Adhesive Bonding System), lining (Ketac-Cem), watger-set filling (Chemfil Superior) and light-cured filling glass ionomer cement
(Vitremer)
were
used as experimental groups.
@ES Results were as follows :
@EN 1. All adhesives in this study showed enough shear tensile bond strength to use clinically except Ketac-Cem.
2. After thermocycling, the shear tensile bond strength of Orthodonitc Adhesive Bonding System and Chemfil Superior were significantly decreased, but that of Phase II was increased. And those of Mono-Lok 2, Ketac-Cem and Vitremer were not
significantly
different from 24 hours (P<0.05).
3. As for adhesives releasing fluoride, the amount of fluoride released went down sharply for 10 days, and after 10 days it showed a little bit decrease. Phase II didn큧 release fluoride after 10 days.
4. After 40 days, Chemfil Superior and Vitremer released significantly greater amount of fluoride than Orthodontic Adhesive Bonding System (p<0.01).
According to the above results, it was considered that glass ionomer cements for filling materials were available to used as orthodontic bracket adhesives. And they were more effective for releasing fluoride than fluoride-releasing resins.
