Study on the occurrence of microorganisms on the post-surgical maxillary prostheses with obturators and in the post-surgical cavities of maxilla.

The bacterial environment of the mouth cavity may be subjected to change under influence of various factors, such as surgical removal of neoplasm tumors and in consequence the wearing of post-surgical prostheses with obturators. The purpose of the paper was to study the conceivable differences in occurrence of particular types of microorganisms found on the margin of post-surgical cavities and on the prosthetic obturators. The performed microbiologic examinations revealed that more pathologic bacterial flora was found on the obturators than in the post-surgical cavities. The authors conclude that the post-surgical patients should pay more attention to the very accurate hygiene of their prostheses and the mouth cavity as well.
