Abstract

SEM investigations have been conducted to determine the influence of the material on tissue/ material bonding.
Extracted, human teeth were used in this study. Resin - modified glass - ionomer cement and resin composites were tested as dental fillings. To reveal the structure of the tissue/ filling interface the teeth were cut parallel to the long axis.
Bonding quality was determined by direct SEM observation. Fluorine release was estimated by microanalysis with the use of X - ray energy spectrometry (EDS). The results show, that investigated materials have good bonding with enamel. Not fluorine release was observed.
