The objective of this research was to determine the level of microbiological contamination on radiographic equipment before, during, and after the taking of intraoral radiographs in the radiology room at the Universidad Norbert Wiener. The methodology used was descriptive, longitudinal, prospective, and quantitative with an applied focus. The population consisted of 3 radiographic units, with a total of 54 swab repetitions (18 before, 18 during, and 18 after the shift). The sampling was non-probabilistic with intentional selection, as the repetitions on each unit made up the sample. The technique used in this research was direct observation. Swabbing was performed on the designated surfaces of the X-ray equipment, and the samples were taken from different parts of the equipment. The Kruskal-Wallis statistical test was applied with a significance level of 5%. The results showed that there was greater microbiological contamination after the radiographic procedure, with Bacillus G-, Cocci G+, and Staphylococcus G+ having a mean of 18.10555 x 10^7 CFU/ml, followed by Bacillus G-, Cocci G+, and Streptobacilli G- with a value of 14.68777 x 10^7 CFU/ml after the procedure. As for fungi, higher contamination was observed before the radiographic procedure at 2.5555 x 10^7 CFU/ml. However, no significant differences were found in microbiological contamination on the radiographic equipment before, during, or after the taking of intraoral radiographs (p > 0.05).
