Abstract
Objective: To test the effect of ficin as an enamel deproteinizing substance on shear bond strength of orthodontic brackets.
Materials and Methods: Forty-two teeth were used and divided into two groups: a control group (enamel surface was not treated with ficin) and a test group (enamel surface was deproteinized by ficin before etching). After bonding, shear bond strength was measured using a universal mechanical test machine. The two groups were compared using independent-samples Student’s t-test (p<0.05).
Results: The ficin group showed higher shear bond strength, the difference was statistically significant (p = 0.037).
Conclusion: A deproteinization step using ficin is recommended to be added to the traditional bonding protocol in order to enhance shear bond strength of orthodontic brackets.
