  • Title: [Scanning electron microscopic study of so-called carvable composite filling materials after over one-year functional period].
    Author: Triadan H.
    Journal: SSO Schweiz Monatsschr Zahnheilkd; 1979 Mar; 89(3):194-202. PubMed ID: 117547.
    Abstract:
    28 class-5 and 16 class-1 fillings were made from the composite material "Epoxydent" on a macaca speciosa monkey and examined with the electron microscope after a 15 months functional period. Statistically significant differences in the size of the marginal space were found to be larger than in comparable composites Adaptic, Concise, Compo-Cap and Cosmic. The spaces were frequently not located on the filling margin but inside, within the filling material. This is attributed to the "carving" technique during the gel phase of setting. The surface shows abrasions and porosities with loss of particles, sometimes fractures and discolored margins with secondary caries. It is not recommended to replace metal fillings by so-called carvable composits.
