Abstract
Aims: This study aimed to evaluate the compressive strength of a fluorescent orthodontic adhesive modified by the incorporation of different concentrations of Zingiber officinale essential oil. Materials and Methods: Compressive strength test groups consisted of the control group, orthodontic adhesive modified with 1% Zingiber Officinale essential oil, and 2% groups, (5 specimens for each group). Cylindrical rubbery molds were utilized to fabricate the study specimens; their diameter was three millimetres while their height was six millimetres, each specimen was constructed by utilizing an incremental approach. Each layer of Fix fluorescent orthodontic adhesive was about 2 mm level, the curing light was applied for 20 seconds. A universal testing apparatus with a cross-head velocity of 1 millimetre/ minute was used to assess the compressive strength. Statistical comparisons were conducted at p> 0.05. Results: The compressive strength of the control group was higher than orthodontic adhesive modified with 1%, and 2% Zingiber Officinale essential oil, but no statistically significant differences were shown among them. Conclusion: The current study concluded that compressive strength reduced after incorporation of Zingiber Officinale essential oil with orthodontic adhesive, however, no evident differences were noticed.
