Comparision of Shear Bond Strength between Ethyl Alcohol Wet Bonding and Conventional Wet Bonding of Orthodontic Brackets – An Invitro Study

Abstract

Aim : The study aimed to assess the impact of ethyl alcohol wet bonding on the shear bond strength (SBS) of orthodontic brackets compared to conventional wet bonding methods.  Materials and Methods : 12 premolar teeth were utilized and divided into two groups: conventional wet bonding and ethanol wet bonding. Each group followed its respective bonding protocol.After bonding, the teeth were immersed in water for complete polymerization.Shear bond strength was assessed using a Universal Testing Machine (UTM).Statistical analysis was performed to compare the shear bond strength between the two groups.  Results : The mean shear bond strength observed in the ethyl alcohol wet bonding group was higher compared to the conventional wet bonding group.Statistical analysis revealed a significant difference between the shear bond strengths of the two groups, with ethyl alcohol wet bonding demonstrating superior results.  Conclusion : The mean shear bond strength achieved with ethyl alcohol wet bonding (6.5 MPa) falls within the optimal range as indicated by Reynolds et al. (1976).Ethanol could serve as a cost-effective alternative to MIP (presumably a bonding agent or adhesive used in conventional wet bonding). This study suggests that ethyl alcohol wet bonding may offer advantages in terms of shear bond strength compared to conventional wet bonding methods, potentially providing a viable alternative for orthodontic bracket bonding
