[Scanning electronmicroscopic study of 3 composite filling materials after 1 year's use].

This is an in-vivo comparative test of two test materials, composites Compo-Cap and Cosmic against Adaptic on a monkey (Macaca speciosa) over one year. No significant differences could be found and the defects on margins and in the surface was similar. Undubitable secondary caries could--unlike in a previous test with Epoxylite--not be found with these fillings.
