소독액이 인상재의 표면특성에 미치는 영향

다국어 초록 (Multilingual Abstract)

Disinfection of dental impression is important process because of contamination which could cause cross-infection. The aim of this study was to evaluate the properties of dental impression after disinfection treatment. We performed the disinfection treatments using hypochlorous acid (Medilox^®). The impression materials were alginates and polyvinyl siloxane. Specimens of each group were prepared by ISO 4823 and ISO 1563. The impression materials were sprayed with 0.5 % sodium hypochlorite, 2 % glutaraldehyde, 0.1 % povidone iodine and 0.006 % hypochlorous acid, en stored for 15 minute in sealed bag. Various tests (e.g., tail reproduction test，compatibility with gypsum，linear dimensional change test, contact angle measurement and scanning electron microscope observation) were performed. The results of all tests showed that there were no significant differences between before and after disinfection treatment (P>0.05). However, case of the contact angle measurement, it is confirmed that hydrophilicity was increased after disinfection treatment (P<0.05). We recommend to use a hypochlorous acid as a dental impression disinfectant.
