In orthodontics, semicritical instruments are used, those that must have a sterilization or disinfection process after each use. These methods are disputed since they are said to result in an unfavorable occurrence of corrosion and reduction in the quality of the instruments. The purpose of this study was to evaluate corrosion in ligature cutters subjected to autoclaving versus high-level disinfection in 2% glutaraldehyde methods. Methods: There were 9 ligature cutters from three different commercial brands that were used: Ix, Td, Oe. The study included; a control group and two experimental groups with autoclaves and 2% glutaraldehyde, that were subjected to 60 cycles administered in intervals of 20 cycles in total being evaluated at four different times. The active part was analyzed by means of scanning electron microscopy using energy dispersive X-ray spectroscopy, the corrosion rate was evaluated by carrying out electrochemical tests of resistance to linear polarization (LPR) and polarization curves (TAFEL), using potentiostat / galvanostat. Results: The cutters that contain chromium within their composition are more resistant to sterilization / disinfection procedures; chemical disinfection when using substances with an acidic pH, is more aggressive than autoclave sterilization. Significance: It is indicated that cutters with high chromium content have greater resistance to corrosion but the study shows that chemical disinfectants with a neutral pH, following the manufacturers recommendations for the use of instruments use and implemented mechanisms.Objetivos: Las medidas de control de las infecciones son importantes para prevenir la contaminación cruzada. En ortodoncia, se utiliza instrumental semicrítico, los que deben tener un proceso de esterilización o desinfección después de cada uso. Estos métodos son discutidos por el efecto desfavorable en cuanto a la ocurrencia de corrosión y reducción en la calidad de los instrumentos. El propósito de este estudio fue evaluar la corrosión en cortadores de ligadura sometidos a métodos de esterilización en autoclave versus desinfección de alto nivel en glutaraldehido al 2%. Métodos: Se emplearon 9 cortadores de ligadura de tres marcas comerciales diferentes: Ix, Td, Oe. El estudio incluyó un grupo control y dos grupos experimentales autoclave y glutaraldehido al 2%, sometidos a 60 ciclos con intervalos de 20 ciclos para ser evaluados en cuatro tiempos. Se analizó la parte activa mediante microscopía electrónica de barrido con espectrometría de dispersión de energía de rayos X, se evaluó velocidad de corrosión realizando pruebas electroquímicas de resistencia a la polarización lineal (RPL) y curvas de polarización (TAFEL), mediante potenciostato/galvanostato. Resultados: Los cortadores que dentro de su composición tienen cromo son más resistentes a los procedimientos de esterilización/desinfección; la desinfección química al usar sustancias con un pH ácido, es más agresiva que la esterilización en autoclave. Significancia: Se indica que los cortadores con alto contenido en cromo presentan mayor resistencia a la corrosión y se recomienda desinfectantes químicos con un pH neutro, siguiendo las recomendaciones de uso publicadas por los fabricantes de los instrumentos y mecanismos implementados.spaAcceso restringidoCorrosión, electroquímica, instrumental de ortodoncia, cortador de ligadura, desinfección de alto nivel, esterilización, autoclave, glutaraldehido.Trabajo de grado (Pregrado y/o Especialización)Corrosion, electrochemistry, orthodontic instruments, ligature cutter, high-level disinfection, sterilization, autoclave, glutaraldehyde.info:eu-repo/semantics/restrictedAccesshttp://purl.org/coar/access_right/c_16ecAdhikari SP, Meng S, Wu Y, Mao Y, Ye R, Wang Q, et al.
