• Abstract:

  Goal: The study aimed to analyze the cleaning process and the effectiveness of sterilization of endodontic files used by undergraduate students of the Dentistry course of a college in Alagoas. Materials and methods: Endodontic files were collected with students from the 7th, 8th, 9th and 10th periods who were willing to voluntarily participate in the research. To assess the sterility of endodontic files, these instruments were placed in test tubes containing BHI (Brain Heart Infusion) broth and later taken to a bacteriological oven at 37ºC for analysis at 24, 48 and 72 hours. Files that caused turbidity in the culture medium were considered infected. Results: It was observed that 6.9% of the collected files were contaminated, even after the sterilization process. Among these, 57.1% belonged to academics from the 7th period, 14.3% from the 8th period and 28.6% from the 9th period. The 10th period showed no infected files. Conclusion: It is necessary to reinforce the cleaning protocol of endodontic files, as well as to emphasize the importance of its correct execution for endodontic treatment.
