[Diffusion of elements of glass ionomer cements placed in a dentin cavity: influence on pulp pressure].

The biocompatibility of glass ionomer cement with silver and titanium ions is studied in vivo on dog's canine. Class V cavities, side by side the pulp, are prepared and Ketak Silver cement is placed inside. Variation of pulp pressure are recorded before and after the cement's applying, after which the crowns are cut and broken at the filling level, the different components part diffusion through the dentin are placed in prominent position by means of a microanalysis and a cartography of the sample is obtained by colorimetric picture. The pulp's haemodynamic responses to Ketak Silver are in harmony with the metallic ions diffusion and specially with silver.
