Background: Cocoa bean extract are among the richest sources of antioxidant, as well as many flowers, fruits, nuts, seeds and vegetables. They have been shown to improve the mechanical properties of demineralized dentin with the potential to crosslink collagen. Aim: To evaluate, if cocoa extract increases the Shearbond Strength (SBS) of orthodontic resin when bonding to enamel, In this invitro study 30 extracted teeth samples were divided into two groups,which had 15 specimens each, Group I (Control)and Group II (Test). Teeth in the test group were soaked for 10 minutes in 30% cocoa extract before bonding, whereas teeth in the control group were bonded directly without immersing in cocoa extract. SBS were measured using a universal testing machine to check the bond strength. Results:The mean shear bond strength in test group was 6.54 Mpa with a standard deviation of 0.38 and 10.85 Mpa with standard deviation of 1.3 in control group. The shear bond strength of control group was significantly higher than the test group. This indicates that immersing in cocoa extract reduces the shear bond strength of resin used on enamel.
