[Descriptions and comparative changes of modifications on ultrastructure of cocci and bacteridium of saliva under "in vitro" influence of sparse and dense solutions of chlorhexidine di-gluconate].

Abstract

In our investigation we have studied and analysed the modifications on the ultrastructure of the cocci and bacteridium of saliva under "in vitro" influence of sparse and dense solutions chlorhexidine di-gluconate. We noticed that the sparse solutions of the drug revealed ruptures of the cellular wall and of the cellular membrane as well as "plasmoptysis" and "plasmolysis". The protoplasm, showing a general coagulation, damage of the cytoplasmic membrane and the cellular wall and in concentrations of 1% and 2% we observed a disorganisation of the nuclear chromatin.
