[Adhesiveness of microorganisms to some soft resins]

Considering the fact that one of the main causes of the soft resins modification in prosthetic dentistry is the effect caused by a variety of microbe, experiments were carried out "in vitro" of microbe, experiments were carried out "in vitro" on three of the most commonly used resins with a modified method, based on the use of lymphoprep, it has been possible to study the capacity for adherence of bacteria and mycetes commonly found in the oral flora, over both the short and the long term. Results of this research underlined how ethylene and acetate based vinyl resins, probably for their physical and chemical characteristics, provide the best resistance to colonization by microbes, with special reference to mycetes. This is presumably an advantage for their use "in vivo" for a greater and improved conservation over the time, owing to this reduced interaction with microbe action.
