Abstract
Mass distribution of different infectious diseases appears even more likely in dentistry than other medical specialities. The purpose of the study is to examine different impressions with alginate materials in order to demonstrate the contamination with different pathogens. Material and method. 63 patients were included in this study. They required specific prosthetic treatment. Preliminary impression were obtained with irreversible hydrocolloid material and microbiologically tested shorthy after removal from the mouth, after washed throughly with cold water and after decontamination with specific desinfectants. Results. Microbiologic records on the alginate impressions in different stages, revealed a reduction in number of bacteria, but not completely absence, regardless of the type of decontamination substance. Conclusions. The presence of different pathogens on the surface of irreversible hydrocolloid impresions is certain. There are residual bacteria which differ from one substance to another, irrespective of cleaning stages and decontamination materials used in daily manipulation of dental impresion. Even if time consuming, decontamination of alginate impression is compulsory in dentistry.

Am realizat un studiu mixt atât cu componentă de medicină dentară, cât şi cu componentă de microbiologie, privind contaminarea microbiană a unor materiale de amprentă, în mai multe etape:
Summary
Studiul a fost realizat pe un lot de 63 de pacienţi care s-au prezentat pentru tratamente protetice de specialitate. Amprentele preliminare realizate cu hidrocoloizi ireversibili au fost verificate din punct de vedere microbiologic după îndepărtarea din cavitatea bucală, după clătirea intensivă cu apă şi după decontaminarea cu substanţe chimice cu potenţial dezinfectant. Etapele succesive în care s-au realizat înregistrări microbiologice au arătat o reducere a bacteriilor prezente la nivelul amprentelor din hidrocoloizi ireversibili, dar nu o îndepărtare completă, indiferent de tipul de substanţă folosită pentru decontaminare. Prezenţa microorganismelor cu potenţial patogen la nivelul amprentelor realizate cu hidrocoloizi ireversibili este o certitudine. Chiar dacă este o etapă consumatoare de resurse şi timp, decontaminarea trebuie să devină o etapă obligatorie în realizarea lucrărilor protetice
