Evaluations of dimensional changes after disinfection of elastomeric impression materials with Ozone water, sodium hypochlorite, and autoclave method

To evaluate the dimensional changes after disinfection of elastomeric impression materials with Ozone water, sodium hypochlorite, and autoclave method. A total 40 impressions were made divided into 4 groups according to type sterilization method used (Group 1: Control without use disinfectant, Group 2: Autoclave, 3: 4: ozone water method) 10 in each group. Impression group contaminated Pseudomonas aeruginosa poured dental stone subjected for different procedure. Microbial evaluation was done by cultural stability accuracy. Results statistically evaluated. The Significant difference seen microbial load hypochlorite followed compared control (P < 0.001). Autoclave methods are effective reducing count can be as an disinfectant
