Fluoride Release from Hard Dental Tissue Restorative Materials

Aim: The aim of this in vitro study was to determine and to compare the level and dynamics of fluoride release in three types of current filling materials. Materials and methods: luoride release was measured in GC Kalore composite, glass ionomer GC Equia cement and Shofu Beautiful II giomer. 20 discs were made from each material (8 mm diameter, 2 mm thickness). Measurements were made during 10 weeks by an ion-selective electrode (ORION EA 940). The linear regression method was used in statistical data processing. Results: The GC Kalore composite released 1.29 ppm F- in 10 weeks of testing. Fluoride release decreased and after 4 weeks of testing, it became impossible to measure by ion-selective electrode. Glass ionomer cement, GC Equia released the greatest number of fluoride ions (24.512 ppm F-) and the greatest number of fluorides was released during the first 24 hours (6.8507 mgF- /L). Giomer Shofu Beautiful II released 4.685 ppm F-. Conclusion: The examined giomer released more fluorides than the composite material and therefore, it can be recommended as a material of choice for esthetic fillings in which the caries preventive effect is also important.
