Tear Strength Evaluation of Maxillofacial Silicone After Disinfection with Oregano Oil Solution

Abstract

The main objective of this study was to evaluate the tear strength property after disinfection with plant-based disinfection solution after different immersion periods. Materials and methods: Forty specimens of VST-30 maxillofacial silicone were prepared then divided into four main groups (n= 10), a control group that was not subjected to disinfection and three experimental groups subjected to disinfection in different immersion time (1 day, 1 month, and 6 months). The experimented groups were immersed in Oregano oil solution. The tear strength test was performed by the use of Universal Testing Machine. Statistical analyzes of the data was perfor med via One-way ANOVA and Tukey HSD Post-hoc test to determine the significant differences between experimen tal and control groups at a level of significance (p ≤ 0.05 ). Results: The tear strength test showed a non-significant difference between the control group and the experimental groups. Also, there was no significant differences among the three experimental gr oups. Conclusion: tear str ength of VST-30 silicone elastomer was not affected after im mersion in 0.4% Oregano solution.
