Causes of contamination in processing fixed prostheses, dental laboratory CURN Cartagena, 2013

Abstract

In making prosthetic may be failures, not being oblivious to this, in the laboratory of dental mechanics of the Corporación Universitaria Rafael Núñez, arises contamination during the manufacturing process of fixed prostheses. To identify the main causes of contamination of denture fixed in manufacture, within the dental laboratory in the CURN, to provide recommendations on control measures, to apply to develop prosthesis. Descriptive – observacional study, population and sample: crowns spruing performed in the laboratory of mechanical dental the CURN in the study period. There is evidence that the main causes of pollution are caused by particles of pollutants suspended in the air, residues of stones of reviewed or arenas of cleaning and surface contamination by biological agents. Pollution occurs basically due to lack of control in the environment of work tools, lack of independence in the areas and lack of observation in manufacturing protocols. Independence in work areas, use instruments unique to each stage of the construction of prosthetic, application apparatus of biosafety according to work.
