Microorganismos localizados en limas utilizadas durante la terapia periodontal pulpar de los estudiantes de la carrera de odontología de la UCSG A- 2023.

Abstract

Introduction: Manual K files from different groups of brands are considered critical instruments according to the guidelines for disinfection and sterilization in healthcare centers and that they may contain microorganisms even before being used. Objective: To determine the microorganisms located in files used during periodontal pulp therapy of students of the dental career at UCSG A-2023. Materials and methods: It is of a mixed type, the universe was composed of 50 samples of files used in the dental clinic by UCSG students during the semester A-2023. Regarding the sample, 21 were obtained, with a margin of error of 5% and a confidence level of 95%. Analysis and discussion of results: In consideration of the results obtained, as characteristics of the samples, it was found that 42.86% of the samples were upper incisors. The most used K file was 15 with 52.38%. In addition, 61.80% of the patients attended were asymptomatic, while 33.33% presented pain. At the same time, it was found that 33.33% of the patients had asymptomatic irreversible pulpitis and pulpal necrosis individually. And 95.24% was for the first infection. On the other hand, it was found that 80.95% of the samples were negative for microorganisms, although 14.29% were positive for Gram-negative Bacilli and 3.00% for Gram-positive Cocci. Conclusion: Although 80.95% of the samples were negative, the presence of microorganisms in the files used by the students could be found in 17.29%, this may be due to localized infection in the sample ducts, which can occur for different reasons. factors, further studies are recommended to effectively determine the presence of pathogens.
