• Abstract:

  Endodontic treatment is not only successful in the correct diagnosis and execution of the technique, but it is especially successful in the dental surgeon's care of the aseptic chain before, during and after patient care. Goal: To evaluate the effectiveness of decontamination of cleaning and sterilization processes of endodontic instruments through microbiological and visual evaluation.Materials and Methods: This is an experimental study with a quantitative and descriptive approach, where 40 25 mm K#15 endodontic files were analyzed and divided into 4 experimental groups (n=10). The endodontic files underwent different cleaning methods, G1- brushing with neutral detergent, G2- ultrasonic bowl with enzymatic detergent and brushing with neutral detergent, G3- brushing with neutral detergent and sterilization and G4- ultrasonic bowl with enzymatic detergent, associated with brushing with neutral detergent and sterilization. Results: After performing the cleaning methods, the files were submitted to microbiological and visual evaluation. Thus, the microbiological analysis showed the turbidity of the files: which G1, G2, G3 and G4 turbid 50%, 70%, 0% and 10% respectively. In the visual analysis the percentage of contaminated files were: G1, G2, G3 and G4 were respectively 30%, 70%, 0% and 10% contaminated. Conclusion: It is concluded that the samples that went through the sterilization process, for the most part, are in sterility conditions, especially those that previously underwent brushing with neutral detergent, associated with sterilization.
