FERREIRA, Rilton Emanuel Cavalcante et al. Effectiveness of three substances disinfectants in dental radiology practice. Rev. Bras. Odontol. [online]. 2016, vol.73, n.1, pp. 14-19. ISSN 1984-3747.

The study aimed to evaluate bacterial prevalence of dental radiology equipment and to test the effectiveness of 03 disinfection substances. 04 Surfaces were evaluated in 04 clinical (locating cylinder, lead apron, trigger X-ray and darkroom) being tested: Alcohol 70%, sodium hypochlorite 2.5% and 0.2% peracetic acid. Biochemical methods have been used for identification. In 91.7% of the areas examined were bacterial contamination, the most prevalent being Staphylococcus genus, followed by gram-positive bacilli. The 2.5% sodium hypochlorite and 0.2% peracetic acid reduced the bacterial contamination of 93.8% to 6.3%, while the 70% ethanol showed only 31.2% of bacterial absence after use.
