The Effect Decontamination of Sodium Hypochlorite 0.5% on shear strength buccal tube orthodontic
Abstract
Method: The research design used was the post test only control group design. The total research sample amounted to 52 samples and was divided into 4 groups: group I Clorhexidine 2% for 1 minute, group II Clorhexidine 2% for 5 minutes, group III 0.5% NaOCl for 1 minute and group IV NaOCl 0, 5% for 5 minutes. Post Decontamination of Buccal Tube and bonding shear strength was carried out using Universal Testing Machine. The Kruskal Wallis test was carried out to see the differences in the four groups in the shear strength of attachment and the Mann Whitney test to find out the differences between groups.
Result: The shear strength of the attachment by decontamination using 2% chlorhexidine for 1 minute was higher than the other 3 groups, which was 25.3 J/mm2, the lowest shear strength was for the 0.5% sodium hypochlorite group for 5 minutes, which was 16.5 J/mm2. Kruskal Wallis test results p value 0.000 (p <0.05), a significant difference in the four groups of bonding shear strength. Mann Whitney test (p<0.05) so that there was a significant difference in the buccal tube attachment shear strength between groups
Conclusion: There is an effect of shear strength of attachment on the buccal tube post decontamination
