- Abstract
Brief Introduction: This study was done to determine the effect of 2 adhesion promoters: Enhance L.C. (Reliance) and Ortho Solo™ (Ormco) on the shear bond strength of new and recycled orthodontic brackets and the amount of remnant adhesive on the teeth after debonding. Materials and Methods: Sixty new and sixty recycled brackets were bonded to 120 extracted human premolars with composite resin and divided equally into 6 groups based on the 2 adhesion promoters used: (1) New brackets/no adhesion promoter, (2) Recycled brackets/no adhesion promoter (3) New brackets/Enhance L.C. (4) Recycled brackets/Enhance LC (5) New brackets/Ortho Solo™ (6) Recycled brackets/Ortho Solo™. Statistical analysis used: Comparision of shear bond strength was done by Kruskal-Wallis and for inter group multiple comparison Mann-Whitney was performed. The chi-square (x2) test was used to determine significant differences in the ARI scores between the different groups. Significance for all statistical tests was predetermined at P < .05. Results: New brackets/OrthoSolo™ (Group V, 13.151 ± 0.932) had the highest shear bond strength followed by New brackets/Transbond XT (Group I, 11.491 ± 1.72) > New brackets / Enhance L.C. (Group III, 11.069 ± 1.538) > Recycled brackets/OrthoSolo™ (Group VI, 8.255 ± 0.725) > Recycled brackets/Enhance L.C. (Group IV, 7.103 ± 0.898) > Recycled brackets/Transbond XT (Group II, 6.777 ± 0.539). Conclusions: Recycling brackets with Ashpol electropolishing liquid can serve them as new brackets in terms of the clinically acceptable bond strength.
