Leaking of fillers in dental composites
K. J. Soderholm
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.
