Abstract
The purpose of the study was to determine whether Sodium hypochlorite and Glutaraldehyde would be effective for the surface disinfection of contaminated radiographic film pockets with saliva The following results were as obtained 1. Proper times for surface disinfection of 2.0% Glutaraldehyde and 3.5% Sodium hypochlorite were 60 seconds. 2. When films were immerged in 2% Glutaraldehyde solution for 1 minute, baterial colonies were present in 24 cases(80%). 3. When films were immerged in 3.5% Sodium hypochlorite solution for 1 minute, bacterial colony was absent in 25 cases(83.3%). 4. Differences of effectiveness on surface disinfection between 2% Glutaraldehyde and 3.5% Sodium hypochlorite were statistically significant.
