Abstract:
The aim of the study is to compare the fluoride release and recharge properties of glass ionomer cements and ‘alkasite’.
Specimens of two glass ionomer cements (Fuji Ⅸ GP and Riva Self Cure), ‘alkasite’ restorative material (Cention N) and composite resin (FiltekTM Z350XT) were prepared. The fluoride release of each specimen was measured for 28 days. Thereafter, 1.23% acidulated phosphate fluoride (APF) gel was applied to experimental groups. No treatment was performed on control groups. The fluoride release was measured for additional 7 days to evaluate the fluoride recharge properties of each materials.
The fluoride release was highest in Riva Self Cure, followed by Fuji Ⅸ GP, Cention N (p < 0.05). Fluoride release of Cention N was measured to be approximately 49% of Fuji Ⅸ GP’s. After the application of 1.23% APF gel, increases in fluoride release were observed in Riva Self Cure, Fuji Ⅸ GP and Cention N (p < 0.05). Fluoride recharge was observed in Cention N as well as in glass ionomer cements. Further studies are required to evaluate the anti-cariogenic properties of Cention N at clinical conditions.
