Evaluation of the Effectiveness of Sterilization of Dental Instruments at the Unibe Dental Clinical
Introduction: In the field of dentistry, one way to prevent cross-contamination between patients is by eliminating blood waste and other fluids that have been obtained during the use of instruments. The objective of this research was to evaluate the effectiveness of autoclaving dental instruments in the areas of Endodontics and Periodontics.
Methods: An in-vitro, experimental and cross-sectional study was performed on a population of 75 students in comprehensive clinics iii, iv and v at the Unibe dental clinic. 60 samples were taken using smears, which were then inoculation on chromo-agar orientation petri plates and subsequently incubated. The sample consisted of: 10 endodontic files in closed boxes before sterilization in the autoclave, the same 10 endodontic files after sterilization in the autoclave, 10 periodontal instruments (curettes and scalers) before and after sterilization in the autoclave with cloths in perforated boxes, and 10 periodontal instruments before and after sterilization in the autoclave with pouches in perforated boxes.
Conclusion: 60% of the endodontic files after sterilization were found not to be contaminated and 69% for both cloths and pouches had no contamination.
