MONGIORGI1, 1Center of Biomineralogy, Crystallography and Biomaterials, University of Bologna, Italy, 2Department of Dental Sciences, University of Bologna, Italy Objectives: The aim of the present study was to evaluate the fluoride releasing from two commercial products (adhesive and composite) using two different analytical techniques. Methods: Ten samples of dental adhesive ONE-UP Bond® F Plus Self-Etching Bonding Agent (Tokuyama Dental Corporation, Tokyo, Japan) and ten samples of composite BEAUTIFIL® Intro set (Shofu Dental Corporation Inc, kyoto, Japan) were prepared by using acrylic moulds with semi-spherical shape (d=10.3 mm, h=4.4 mm). The samples were stored in 55 ml of citric acid solution 0,02 M (pH 2.5) at 37° C. The storage solutions were modified after 7 days, 1,2,3 and 6 months. The obtained solutions were divided into two parts and analyzed for F content using a selective ion-electrode (Orion Research Inc., mod. 940911, Cambride, MA, USA) and a chromatographic column (ICS-90 ion-chromatography system, DIONEX, Sunnyvale, CA, USA). Results: In the table chromatographic and potentiometric analyses respectively. Conclusions: The study shows that the two techniques give quantitative of fluoride releasing data statistically different. The chromatographic technique showed a linear pattern of releasing different from potentiometric technique and the chromatographic technique may consequently be considered more adequate. -------------------------------------------------------------------------------- Abstract ID#: 102496 Password: 991502 Submitter's or presenter's Email: silvano.zanna@unibo.it Program Selection: Dental Materials 6: Polymer-based Materials - Physical Properties and Performance Topic: DM 6 Systematic Review Abstracts Consider for Poster Presentation ONLY: Y The presenter is a Post-graduate student.
