[Reaction of HeLa cells to the presence of Evicrol varnish studied by electron microscopy].
The electron-microscopical changes of cells produced by underlying Evicrol varnish are described. The latter is used in preventive stomatology to underlay fillers, those from composite materials, especially. It is designed to prevent the pulp damage through these materials. The changes of in vitro cultivated cells have in contrast been confirmed with previous experimentation showing that the varnish itself causes toxicity for living cells and therefore is not convenient to undercoat cavities in the proximity of pulps.
