In Vitro Comparative Analysis of the Tensile Strength of Elastomeric Chains Disinfected with Quaternary Ammonium and Alcohol: In Vitro Comparative Analysis of the Tensile Strength of Elastomeric Chains

Abstract - The study compares in vitro the tensile strength of elastomeric chains (EGRT) disinfected with quaternary ammonium and 70% alcohol. It focuses on disinfection protocols in orthodontics, whose vulnerability is due to cross-infections. The research is relevant due to the COVID-19 pandemic, which resulted in the search for new disinfection protocols. The WBRT was disinfected with two agents: quaternary ammonium and 70% alcohol. A universal testing machine was used to measure the tensile force and compare the results to determine the impact of each disinfectant agent. The results indicate that quaternary ammonium and 70% alcohol have different effects on the mechanical properties of Elastomeric Chains (ECs). 70% alcohol tends to degrade mechanical properties more than quaternary ammonium. We can conclude that quaternary ammonium disinfection is preferable to maintain the mechanical properties of elastomeric chains in orthodontics. This study provides valuable information for clinical practice, helping professionals to choose disinfection methods that do not compromise the efficacy of orthodontic treatment. Due to the risks associated with other diseases, such as COVID-19, it is crucial to adopt effective disinfection protocols that do not compromise the mechanical properties of the materials used.
