Evaluation of the Antimicrobial Activity and Dimensional Alterations of Alginate Impression Disinfectants
Abstract - This paper offers a quantitative evaluation of the antimicrobial efï¬cacy of eight different disinfection procedures for irreversible hydrocolloid impressions and the dimensional changes induced by them. Samples were collected immediately after impressions, after the disinfection procedures and over casts and analyzed for bacterial growth. Control, enzyme solutions, acetic acid and ultraviolet irradiation samples showed bacterial growth. Chlorhexidine and 1% sodium hypochlorite presented adequate antimicrobial activity, while 2% sodium hypochlorite solution showed the best results. Dimensional changes were similar to those of the controls in all the tested agents. The results indicated 2% hypochlorite was the most appropriate disinfectant tested.
KEY WORDS: Irreversible hydrocolloid, antimicrobial activity, disinfection, dimensional alteration, sodium hypochlorite, chlorhexidine.
