Abstract:
In our days, a special interest is given for self-adhesive cements, based on resin composites (RBCs). Reported cases of dental restorations decays, are influenced by interface/surface quality and marginal adaptation to dentin and enamel. The behavior is given by organic and inorganic (filler) phase as well. Regarding the organic phase, this is involved in bonding with dentin remains of dental cavity and enamel. Differences were noticed among the investigated materials. Data obtained from EDX reveal major differences between inorganic phase (filler) in specimens and a non homogenous state for all samples. Results are confirmed by the mapping investigation. Low discontinuity areas for samples specimen were remarked for Biscem and RelyXU100 samples and also for MaxcemElite dental cement. Regarding mechanical properties, these are dramatically influenced by the filler. The major determination of properties is given by the particles size and state of homogeneity for a given specimen composition. SEM results revealed a textured structure with a small filler particles size for RelyXU100 than the other samples.
