Abstract
Background: An orthodontic bonding should be durable to minimize inadvertent debonding, minimize enamel damage, and enabling the removal of the bracket with little to no harm to the tooth. Objectives: The objective of this study was to investigate the effect of magnetized water as a natural mouthwash on the shear bond strength of an orthodontic adhesive in comparison to chlorhexidine. Materials and Methods: A total of 30 extracted premolars for orthodontic intention were gathered and used in this study. After bracket bonding, the samples were randomly distributed into three groups. Group 1: Samples were immersed in magnetized water, group 2: samples were immersed in chlorhexidine Digluconate (0.2 %) mouthwash, and group 3: samples were immersed in Distilled water. Brackets were debonded after 2 weeks of immersion, measuring the shear bond strength by universal testing machine (Gester–China). The adhesive remnant index for each sample was determined. One-Way ANOVA and Duncan’s multiple range test were used for comparison of the significant difference between the groups for shear strength. While Kruskal-Wallis test was used for comparison of significant difference between the groups for adhesive remnant index. Results: Distilled water group had the highest mean value of shear bond Strength, followed by the experimental group MW, while the Chlorhexidine group significantly shows the lowest mean value. Conclusion: It can be supposed that magnetized water as a mouthwash has comparable effect that is not significantly differ from the DW, while significantly higher than Chlorhexidine mean values of shear bond strength.
