[Methods for the biological testing of dental materials on cell cultures].
This paper discusses some of the methods used by for making basic biological tests of stomatological materials. Although we do not dispense with the use of methods based upon the observation of fixed and, possibly, stained cells and allowing the states assumed by cells in a certain period of time to be noted, yet we believe that far better results may be obtained from tests enabling the development of changes of living cells cultivated in vitro to be followed. The results of the experiments conducted by the authors indicate that it is possible for the final effect to be modified in dependence upon the type of material used, its concentration, or the time allowed to elapse from the preparation of the particular material and that an observation of living cells procides much more information about the character of alterations and, more specifically about the time course of changes. If necessary, this method may be supplemented by an electronmicroscopical analysis of the changes produced.
