Effect of the gel form of eucalyptol on the shear bonding forces of orthodontic brackets

Abstract

Background/purpose: In this study, we investigated the effects of a gel form of eucalyptol oil used for debonding orthodontic brackets. It was hypothesized that the use of this gel would lower the shear bonding forces between the bracket and the surfaces of human teeth. Materials and methods: Two types of brackets (metal and ceramic materials) and two kinds of gel forms were used. All experimental samples were debonded using a JSV H1000 testing machine. Results: A statistically significant decrease was observed in the shear bonding force for metal brackets using eucalyptol, regardless of whether it was in a liquid or a gel form (P < 0.05). Conclusion: The most efficient way to reduce shear bonding forces between a metal orthodontic bracket and a tooth surface during a debonding procedure may be to use eucalyptol mixed with Carbopol for 15 minutes.
