[The effect of the density, porosity and surface properties of plastic bases of upper dentures on the palatal mucosa].
In a 14-day test with 50 probands, the effects of a heat-curing resin and a self-curing resin on the palatal mucosa of the test persons were tested by means of exfoliative cytology. It was shown that the keratinization index increased considerably during wearing the plates. It was not possible to demonstrate differences in the effect of heat-curing resins and that of self-curing resins. The different isolation with alginate film or tinfoil did not, in general, have any influence on the cytogram either. Roughness of the surface resulted in a slight increase of the intermediary cells.
