A comparative evaluation of effect of fluoride release on push-out bond strength of GIC and cention-n.

From the past till the present there has been numerous direct filling materials introduced in the dentistry. These materials replaces the specialized tissues of the tooth that have been lost due to caries, as it can further leads to impairment of shape and functioning of the tooth. These materials have exponentially evolved ranging from amalgam to Glass Ionomer Cement and composites. GIC is well liked in dentistry due to its fluoride releasing nature, it is aesthetically good and have variable other properties. But due to its poor mechanical properties it cannot be used in stress bearing areas. To overcome the shortcomings, new materials have been introduced that is Cention-N. Cention-N not only releases fluoride but also release calcium and hydroxide ions. The hydroxyl ions emission can neutralize the acidity caused by the microorganisms which leads to prevention of demineralization. Many factors affect the amount of fluoride release in GIC and Cention-N. Anticariogenic effect of fluoride depends on the amount and time of fluoride release. Due to release of ions from these materials there can be effect on the bond strength of GIC and Cention-N. So the aim of this study is to find the effect of fluoride release on bond strength of Cention-N and GIC. [ABSTRACT FROM AUTHOR]
