Defleksi Kawat Cuniti Ortodonti dalam Obat Kumur Klorheksidin, Klorheksidin Fluorida, dan Kitosan

Abstract

Introduction : In the process of tooth movement, the deflection ability of fixed orthodontic archwires is critical. Chemicals such as mouthwash can affect the deflection of the archwire. The purpose of this study was to examine the effect of chlorhexidine mouthwash, chlorhexidine fluoride and chitosan on CuNiTi archwire deflection in orthodontic treatment at different times. Material and Method : Total of 72 samples, 4 mm CuNiTi archwires 0.016x0.025” were used and immersed in artificial saliva (control group), 0.12% chlorhexidine, chlorhexidine fluoride and 2% chitosan. Each group was divided into 3 immersion times (2, 4 and 6 weeks). The mouthwash immersion time in treatment group was carried out for 28 minutes, 56 minutes, and 84 minutes. The duration of immersion was simulated with the patient's gargling time in 1 day, which was 2 x 1 minute. Deflection was evaluated by using the three-point bending test method which was carried out by applying a pressure of 5 mm at a speed of 1 mm/minute. One Way ANOVA and Post Hoc tests were performed for data analysis. Results : There was a significant difference in CuNiTi archwire deflection between the treatment groups on the 6th weeks. There was a significant difference in chlorhexidine fluoride and chitosan groups in terms of immersion time. No significant differences was found between the control group and treatment group at each immersion time. Conclusion : Clorhexidin fluoride and chitosan immersion may affect archwire CuNiTi unloading force, while chlorhexidine has no effect on it.
