Outline of Final Research Achievements

Composite resin has advantages of aesthetic, minimally invasive for teeth, so it is often used in daily practice. However, it has still problem in long term durability. One of the reason was due to degradation of silane coupling for fillers. However, there was no study to investigate the effect of filler types and its coupling method. So in this study, we investigated the influence of filler type and treatment method of filler on durability of fillers in adhesive layer by the electron microscope observation. It was found that type of fillers and its treatment affected the durability of the filler.
