<sec><h3>Aim:</h3>
<p>This study examined the bond strength associated with Denteshield<sup>®</sup> Primer as a replacement for a conventional, non-antimicrobial, orthodontic primer.</p>

<p>Sixty human premolar teeth were divided into three groups (<italic>n</italic>=20).

Light-cured Transbond XT<sup>TM</sup> adhesive resin was utilised to bond a bracket to each sample tooth following the application of the assigned primer. Ten samples from each group were tested for shear bond strength using a universal testing machine. The remaining 10 samples from each group underwent bracket debonding using a debonding plier. Applying an adhesive remnant index, each sample was scored under a microscope at 2.5× magnification. The data were analysed using One-way ANOVA, the Tukey post hoc test and the Kruskal–Wallis test.</p>

Aim:
This study examined the bond strength associated with Denteshield® Primer as a replacement for a conventional, non-antimicrobial, orthodontic primer.

Materials/methods:
Sixty human premolar teeth were divided into three groups (n=20). Each group was assigned to receive either Denteshield®, Pro Seal® or Transbond XT TM primer. Light-cured Transbond XTTM adhesive resin was utilised to bond a bracket to each sample tooth following the application of the assigned primer. Ten samples from each group were tested for shear bond strength using a universal testing machine. The remaining 10 samples from each group underwent bracket debonding using a debonding plier. Applying an adhesive remnant index, each sample was scored under a microscope at 2.5× magnification. The data were analysed using One-way ANOVA, the Tukey post hoc test and the Kruskal–Wallis test.

Results:
The mean shear bond strength (MPa) of the three groups was: Denteshield® (33.18 ± 13.56), Pro Seal® (23.68 ± 12.04) and Transbond XTTM primer (26.19 ± 9.44). There was no significant difference in the shear bond strength across all three groups (p = 0.19). The adhesive remnant index results also showed no significant differences between the three groups (p = 0.278).

Conclusion:
Based on the shear bond strengths obtained in this study and the previously reported values necessary for clinical use, all three primers appear adequate for clinical use. (Aust Orthod J 2022; 39: 49 - 54. DOI: 10.2478/aoj-2023-0009)
