The two instruments were applied and were trained by an audiovisual video; it was expected a month and the same survey was conducted. The research took into account at all times the resolution 008430 1993 which governs the ethical considerations for research in Colombia. For results Chi2 statistical coefficient for bivariate analysis processing database in SPSS 21 was used. Results: It was found in discreet observation that there are flaws in the implementation of the steps of disinfection of impressions in very high percentage and the level of knowledge before, good 3.3%, average 24.4%, mean 72.4% and after the educational intervention rating change significantly: 63.4% good, fair and poor 29.3% only 7.3%.
