THE EFFECT OF GIC RESTORATION TO SALIVARY FLUORIDE CONCENTRATION

Abstract

SalGlass ionomer cement (GIC) is a fluoride containing restorative material which can inhibit carious lesion. This study was performed to observe salivary fluoride change in artificial alive. Twenty premolars were restored with GIC and immersed in Fusayama artificial saliva (15 ml, pH 6,8) for 1, 2, and 3 days. Unrestored part of teeth was coated with varnish. Fluoride contents measurements were performed by taking 5 ml of artificial saliva of each group being measured with spectrophotometer The result showed that the highest fluoride contents (3,317 +- 0,168) was on the first day of immersion and significantly decreased in the second and third day (2,267 +- 0,72, 1,455 +- 0,186, alternatively). It was concluded fluoride was released from GIC restoration and the release was decreased with time.
