[Isolation of dental pulp from the deleterious effect of composition material by varnish films of dentin Adhesit and cyanacrylate B-100--experimental-morphological studies].

Abstract

The protective properties of varnish films of dentin adhesit and cyanacrylate B-10 versus the toxic action of the compositional material have been studied in experiments on dogs. For that purpose, 45 cavities, class V with size 2:4; 1.5 mm were made. Dentin was isolated by a film from the experimental materials. The control group of teeth were made inlays from phosphate cement. The histopathological reaction of the dental pulp to the materials on trial was determined on day 3, and 1 and 3 months of the beginning of the experiment. No changes, characteristic for acute or chronic inflammatory reaction were established. The good, both immediate and late, results from the experiment are a good reason to admit that the adhesives obtained are suitable for varnish isolation of dental defects with superficial and moderate depth and could be applied with success in the clinical practice under the compositional material. They have no effect on the final aesthetic effect of the obturations.
