| Abstract: | Public awareness of infectious diseases has focused attention on the prevention of nosocomial disease. Difficulties in sterilizing impressions have led to chemical disinfection as an alternative. Recent literature indicated a lack of consensus between researchers about distortion caused by disinfection. A polysulfide, polyether, and vinyl polysiloxane were disinfected by immersion in iodophor, sodium hypochlorite, and glutaraldehyde. Distortion was evaluated by use of a stainless steel die (ADA specification No. 19). Linear dimension variations after disinfection were clinically insignificant. |
