Abstract
Objectives: This study aimed to develop novel self-adhesive resins for orthodontic bracket bonding that can provide clinically acceptable bond strengths, leave minimal remnant adhesive and enamel damage upon bracket debonding. Materials and Methods: A plain self-adhesive resin was used as a control, from which three main modified self-adhesive resin groups were developed for bracket bonding: bioactive glass, strontium fluoride and grape seed extract. All groups were subjected to three artificial aging models prior to shear bond strength, adhesive remnant index, enamel damage index and micro-hardness assessments. Results: All groups yielded clinically acceptable shear bond strength values. The addition of 0.5% grape seed extract to plain self-adhesive resin+1% bioactive glass yielded the highest shear bond strength, minimal adhesive remnant index and minimal enamel damage post debonding, yet the differences were statistically insignificant (p>0.05). The best performance regarding microhardness was displayed by the addition of 0.5% grape seed extract. Conclusions: The formulation (1% bioactive glass+ 0.5% grape seed extract) yielded clinically satisfactory shear bond strength, minimal adhesive residue, minimal enamel damage, and highest micro-hardness mean value as compared to the control and other experimental self-adhesive resin groups.
