| Abstract |
|
This study was performed to compare the fluoride release pattern and compressive strength of recently developed resin-modified glass ionomers(KetacTM N 100 and Fuji Fil LC) with those of conventional glass ionomer restorative material(Fuji II LC). Fifteen sample discs(6 mm diameter and 1 mm height) were prepared for each tested material. The fluoride release was measured by pH/ISE meter(750P, Istek, Korea) for 31 days. For compressive strength experiment, fifteen cylindrical specimens were prepared for each tested material. Each specimen was submitted to compressive strength testing in an universal testing machine(Kyung-sung Testing Machine Co., Korea) at crosshead speed of 5.0mm/min until failure. The results can be summarized as follows; 1. Fuji Fil LC released the highest amount of fluoride, followed by Fuji II LC and KetacTM N 100(p<0.05). 2. The compressive strength of Fuji Fil LC was the lowest(p<0.05). However, no significant difference was found from Fuji II LC and KetacTM N 100(p>0.05). By considering the above results, careful case selection and accurate clinical application is recommended when using KetacTM N 100 and Fuji Fil LC. |
