The Effect of Dental Unit Waterline Antimicrobials on the Shear Bond Strength of Orthodontic Brackets
Abstract
Introduction: Dental unit waterline (DUWL) antimicrobials have been widely used to prevent the formation of microbial biofilms in the dental unit water delivery system. Although there are many DUWL antimicrobials on market, their effects on the bond strength of orthodontic brackets are still controversial. Objectives: To evaluate the effects of three common DUWL antimicrobials on the shear bond strength (SBS) orthodontic brackets. Methods: A total of 56 extracted human molar teeth were randomly assigned to one of four groups (14 teeth/group): 1) Control group (deionized water); 2) ICX; 3) Listerine; or 4) Chlorohexidine. Each tooth was cleaned with pumice and then blindly rinsed with the assigned DUWL antimicrobial or control. A 15-second application of 37% phosphoric acid gel was applied and blindly rinsed again with the assigned DUWL antimicrobial or control, before the bonding of standard orthodontic brackets to each tooth. Within 30 minutes of bonding, the SBS of each bracket was blindly tested using a universal testing machine (MTS Insight). One-way Analysis of Variance (ANOVA) was used to analyze the differences in SBS between 4 groups.
