The aim of this study was to identify the presence and causes of bacterial growth using biological indicators in dental sterilization equipment in San Luis Potos\u00ed, S.L.P., Mexico, with different consecutive measurements over a year. Methods: This longitudinal cohort, conducted from January 2022 to January 2024 in San Luis Potos\u00ed, Mexico, aimed to identify the presence and causes of bacterial growth in dental sterilization equipment using biological indicators. A total of 207 dental offices were approached, and 175 participated, providing data through questionnaires and monitoring sterilization cycles with BIs. The checks were bimonthly for one year, with a total of six checks. Results: (a) An 11% (n = 1188) incidence of bacterial growth was observed, with a higher percentage in dry heat equipment (13%). (b) Upon analyzing the six consecutive verifications over a year, no statistically significant differences were observed in the failures of the sterilization cycles when comparing the two pieces of equipment. (c) Error in temperature and time of the equipment (OR = 4.0, 95% CI = 1.6\u20133.9, p = 0.0001) was significantly associated with the presence of bacterial growth during the one-year period. Conclusions: Monitoring sterilization cycles and identifying the causes of bacterial growth with different consecutive verifications decreased the presence of bacterial growth (failures) during the one-year period.<\/jats:p>","DOI":"10.3390\/medicina60091525","type":"journal-article","created":{"date-parts":[[2024,9,19]],"date-time":"2024-09-19T03:34:20Z","timestamp":1726716860000},"page":"1525","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Presence and Causes of Sterilization Equipment Failures with Biological Indicators in Dental Offices in Mexico: A Longitudinal Cohort"],"prefix":"10.3390","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0056-5901","authenticated-orcid":false,"given":"Nuria","family":"Pati\u00f1o-Mar\u00edn","sequence":"first","affiliation":[{"name":"Clinical Research Laboratory, Faculty of Stomatology, Autonomous University of San Luis Potos\u00ed, San Luis Potosi 78290, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorena Dafnee","family":"Villa-Garc\u00eda","sequence":"additional","affiliation":[{"name":"Clinical Research Laboratory, Faculty of Stomatology, Autonomous University of San Luis Potos\u00ed, San Luis Potosi 78290, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yolanda","family":"Ter\u00e1n-Figueroa","sequence":"additional","affiliation":[{"name":"Faculty of Nursing and Nutrition, Autonomous University of San Luis Potos\u00ed, San Luis Potosi 78290, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1410-9491","authenticated-orcid":false,"given":"Carlo Eduardo","family":"Medina-Solis","sequence":"additional","affiliation":[{"name":"Academic Area of Dentistry of Health Sciences Institute, Autonomous University of Hidalgo State, Pachuca 42160, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yesica Yolanda","family":"Rangel-Flores","sequence":"additional","affiliation":[{"name":"Faculty of Nursing and Nutrition, Autonomous University of San Luis Potos\u00ed, San Luis Potosi 78290, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco Felipe","family":"Salas-Orozco","sequence":"additional","affiliation":[{"name":"Clinical Research Laboratory, Faculty of Stomatology, Autonomous University of San Luis Potos\u00ed, San Luis Potosi 78290, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fidel","family":"Mart\u00ednez-Guti\u00e9rrez","sequence":"additional","affiliation":[{"name":"Faculty of Chemical Sciences, Autonomous University of San Luis Potos\u00ed, San Luis Potosi 78290, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eva Concepci\u00f3n","family":"Aguirre-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Clinical Research Laboratory, Faculty of Stomatology, Autonomous University of San Luis Potos\u00ed, San Luis Potosi 78290, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,19]]},"reference":[{"key":"ref_1","first-page":"1488","article-title":"Daily Use of Biologic Indicators in General Dental Practice","volume":"87","author":"Kunyk","year":"2021","journal-title":"J.
