WEBER, Alexandre et al. Microbiological analysis of occurrence of bacterial contamination of surgical table comparing 20 thickness and 40 thicknes. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2016, vol.16, n.2, pp. 13-16. ISSN 1808-5210.

The cleaning and disinfecting fixed operative surfaces and exposed parts of the dental unit significantly reduces contamination. This study aimed to assess whether there is contamination of the surgical table to use the TNT sterilized in the weights 20 g/m² and 40 g/m². Materials and Methods: The study consisted of two groups, composed of 30 samples (drapes) for each group. After prior disinfection of surgical tables were placed TNT fields. Group 1 was used TNT weight and 20 in group 2 weight 40. The sample collection from both groups was held soon after the placement of surgical fields (time 1) and 1 hour after (time 2). Results: Regarding the occurrence of bacterial contamination, there was no statistically significant difference between time of collection. Even with the disinfecting care of the table and adequate scrub, these fields have not been fully effective. Conclusion: Thus, the sample weight of the TNT 40, both at the beginning of surgery, as 1 hour, better results compared to the TNT weight 20 without statistical differences.
