Leaking of Fillers in Dental Composites
K.-J.M. Soderholm
Department of Dental Biomaterials, College of Dentistry, University of Florida, Gainesville, Florida 32610
The leakage of filler elements from four composites after storage in water was investigated. The results showed that all fillers leaked Si, and that the micro-filled composite and the Ba- and Sr-containing glass composites leaked more Si than did the quartz-containing material. The leakage from the different fillers was explained by hydroxy-ion and stress-corrosion attacks.
