Abstract
The present study aimed to evaluate comparatively fluoride release and recharging ability of various glass ionomer cements under differing temperature conditions. In phase I of the study, fifteen discs (15 mm x 1 mm) each of Glass ionomer cements Fuji I TM luting cement (Group „A‟), Fuji IX TM high strength posterior (Group „B‟), ChemflexTM restorative (Group „C‟) and Fuji II LC TM resin – modified (Group „D‟) (N=10 TOTAL) were prepared and stored in double distilled water at 40C, 370C and 550C. The fluoride released in solution was measured on 1st, 2nd, 5th, 7th and 14th day, using an Ion selective electrode. For phase II, an additional nine specimens of the same materials were prepared and stored in double distilled water at 370C for 30 days, followed by exposure to fluoride solution at same temperature using 200 ppm sodium fluoride solution (Fluoritop TM) for five minutes. The fluoride hence re-released was measured after storage in fluoride solution. Statistical analysis showed that at all temperatures, the Group A showed greatest fluoride release at all measurement points, followed by Group D, and Group B and C respectively. Temperature strongly influenced the fluoride releasing profile of glass ionomers.
