RESUMO
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.

In the medical studies there are many reports on the risk of being infected that the dental staff run, especially as far as it concerns viral diseases. The first worth is about the research into the problem of infections, in particular of viral hepatitis B, made by the Authors in the area of Modena. The results establish the potential presence of such risk; so, the Authors suggest to the people working in edental clinics to follow carefully the procedures of general and specific prevention.

Results with althesin as anaesthetic in out-patient dental surgery are reported. A personal technique is described and reference is made to a large series in an account of the way althesin proved suitable for this form of anaesthesia. Stress is laid on the rarity of intra- and postoperative complications, and the rapid, complete return to consciousness observed after althesin.
