Abstract

Objective: Debonding of orthodontic braces could lead to enamel fracture and moderate discomfort for the patients. This study was conducted to
examine whether eucalyptus oil and eucalyptol were effective in decreasing the shear bond strength and facilitate the debonding of metallic brackets
bonded with bisphenol A-glycidyl methacrylate (bis-GMA) adhesive resin.
Methods: Thirty upper premolar teeth were randomly divided into the following three groups: Group 1 (75% eucalyptus oil), Group 2 (100%
eucalyptol), and Group 3 (aquades; controls). Gemini brackets (3M Unitek, Monrovia) were bonded to the teeth using Transbond XT (3M Unitek,
Monrovia). The areas around the brackets were lubricated with 75% eucalyptus oil, 100% eucalyptol, and aquades for 10 min before debonding.
Results: A significant difference in shear bond strength between Group 2 and the control group was noted (p<0.05).
Conclusion: The findings of this study indicated that eucalyptol can decrease the shear bond strength of bis-GMA-based adhesive resin after 10 min
of application.

Keywords: Bisphenol A-glycidyl methacrylate adhesive resin, Eucalyptus oil, Eucalyptol, Shear bond strength
