Özet

The aim of the study was to determine whether five fluoride containing


resin restorative materials could maintain fluoride release, fluoride re-

charge, and decharge over accelerated aging using active carbon.


Fluoride containing compomer (Ivoclar Compoglass F, Voco Glasiosite),Resin-

Modified Glass Ionomer Filling Material (3M PhotacFil) and glass ionomer


(3M Ketac Molar, Voco IonoStar Plus) were analyzed. Specimens of each

material(n = 5) were fabricated for six test groups : 24h later, 1st accelerated

defluoration for 3 days,1st recharge (with 4min in APF gel), 2nd accelerated

defluoration for 3 days,2nd recharge (with 4min in APF gel),3rd accelerated


defluoration for 3 days. The fluoride release from these specimens was mea-

sured using a HPLC with anion column at the end of the each period.


The amount of fluoride release for aged Compoglass and Glasiosite markedly

increased in water storage after recharging with APF. The difference was not

so great for aged Ketac Molar and Ionofil after first recharge. Photacfil didn't

show alteration in fluoride release by decharge or recharge of fluoride.APF application cause Compoglass,Glassiosite, KetacMolar and Ionofil

to increase fluoride release. But APF didn't affected Photacfil's fluoride

release over aging.
