Introduction: The common problem during the orthodontic treatment is debonding of brackets which leads to failure of orthodontic treatment. The purpose of this study was to determine the effects of four soft drinks (Coca-Cola, 7Up, Tropicana orange, minute maid apple juice) on the shear bond strength of orthodontic brackets. Aim: To evaluate the shear bond strength of orthodontic brackets cemented to natural teeth treated with various soft drinks Materials and Method: A total of 50 extracted human premolars were collected and stored in normal saline solution. They were cleaned and cemented with edge wise stainless steel brackets using composite. Then they were cycled in the said four soft drinks for 2 hours up to 7 days. The samples were tested for their shear bond strength using Universal testing machine (INSTRON) with a cross head speed of 0.5mm/min. The values were tabulated and analyzed statistically using ANOVA. Results: The lowest mean resistance to shearing forces was shown by the control group (18.74 ± 5.15 Mpa) followed by 7Up group (20.17 ± 6.76 Mpa), orange juice group (21.79 ± 5.15 Mpa), Coca Cola group (24.58 ± 11.68 Mpa) and highest resistance to shearing forces by apple juice group (26.04 ± 1.31 Mpa). There was no statistically significant difference among the groups. Conclusion: No significant differences were observed in bond strength of the teeth among the different groups suggesting that consumption of soft drinks after cementation of orthodontic brackets do not significantly affect in de-bonding the brackets.
