Efficacy of three surface disinfectants for dental radiographic films and gloves.
Contaminated radiographic films and gloves may transmit infectious diseases. Objective. To determine whether Pre Sept (NaDC), a sodium dichloroisocyanurate based disinfectant; Bronocide SP (AIP) an alcohol-phenol-iodine disinfectant and polyvinyl pyrrolidine iodine (PVPI) can be used to disinfect radiographic films and gloves. Study design. Radiographic films were contaminated with Candida albicans, Streptococcus mutans, Lactobacilli or saliva and placed in either 0.1, 0.25 or 0.5 NaDC for 1, 2 or 5 min; PVPI for 5 min or sprayed with AIP. Gloves contaminated with C. albicans, S. mutans or Lactobacilli were sprayed with AIP. After treatment the films and gloves were tested for viable microorganisms. Results. A 0.5% solution of NaDC killed all microorganisms after one-minute exposure. PVPI killed 99.8% and AIP spray between 95.8 and 99% of microorganisms. Conclusions. NaDC was the most successful disinfectant in the laboratory and clinical setting followed by PVPI and AIP.
