Extract

The purpose of this work was to examine, by electron microscopy, the mechanism of bacterial binding to oral epithelium in patients with stomatitis using ruthenium red in combination with osmium tetroxide.

Bacteriological semi-quantitative estimation of smear from the palatal mucosa was performed in patients with stomatitis and only patients with viridans Streptococci were further included in the present investigation. Biopsies were taken from the inflamed keratinizing mucosa under regional block anesthesia in agreement with Vancouver guidelines 1978. Control samples were fixed with 1.2% glutaraldehyde (buffered at pH 6.5 with 0.1 M sodium cacodylate) for 2 h at 4° C. Postfixation was performed with 1% osmium tetroxide (buffered at pH 6.5 with 0.1 M sodium cacodylate) for 2 h at 4° C. The other samples were fixed and postfixed by the fixatives mentioned before with addition of 1.6 % ruthenium red in each case.
