    EFFECT OF ACIDULATED PHOSPHATE FLOURIDE APPLICATION ON GLASS IONOMER CEMENT IN TERMS OF MICROHARDNESS

    ABSTRACT Acidulated phosphate fluoride gels are commonly used as caries preventive materials in Pediatric Dentistry while glass ionomer cements are widely used as restorative material. The purpose of this study is to know effect of acidulated phosphate fluoride application towards the microhardness of GIC. This study is laboratory experimental study where ten specimens were prepared from high viscosity GIC which was Fuji IX. Specimens were stored in 50 ml distilled water at first 24 hour at 37°C and then specimens were divided into fluoride group which was immersed in 25 ml of 1.23 % APF gel and control group which was stored 25 ml distilled water for 24 hours at 37°C. The Micromet II Microhardeness Tester, Buehler, IL, USA that was standardized for Vickers hardness test was used to test the specimens at 100 gram load. Data were analyzed using T-test comparison test. The results obtained in this study shows the level of microhardness of the fluoride group (14.34) is much lower compared to the control group (43.21) with a highly significant difference (p
