Abstract

Objective: To compare the shear bond strength and Adhesive Remnent Index (ARI) of metal brackets using four different bonding systems: Heliosit Orthodontic Bonding Material (Ivoclar Vivadent), Ormco Enlight Light Cure Adhesive, Transbond XT Light Cure Adhesive (3M UNITEK) and Light cured Orthofix (Anabond Stedman Pharma Research (P) Ltd.
Materials and Methods: In the present study 120 extracted sound human upper bicuspids were taken and divided into four groups. Group 1: Heliosit Orthodontic Bonding Material (Ivoclar Vivadent), Group 2 : Ormco Enlight Light Cure Adhesive ,Group 3: Transbond XT Light Cure Adhesive(3M UNITEK) and Group 4: Light cured Orthofix (Anabond Stedman Pharma Research (P) Ltd. In all the groups (n = 120) orthodontic metal brackets were bonded with the four different light cure adhesives respectively and all the samples were evaluated for shear bond strength using Instron(3366) universal testing machine at a cross speed of 1 mm/min. The bracket failure mode was examined using Adhesive Remnant Index (ARI). The Inter group comparison (>2 groups) was done using one way ANOVA followed by pair wise comparison using post hoc test. Comparison of frequencies of categories of variables with groups was done using Chi square test. For all the statistical tests, p<0> Conclusion: It was concluded that the mean shear bond strength of the Transbond XT was highest among the four adhesives studied. However all the adhesives tested exhibits adequate bond strength for clinical use and ARI scores was nearly same for the Transbond and Enlight adhesives studied.
