ABSTRACT
Aim:
The objective of this study was to compare the efficiencies of different adhesive systems used to bond orthodontic brackets as well as the fracture pattern during debonding on bovine teeth.Methods:
The sample included 45 specimens assigned to 3 groups according to the adhesive system applied Group I Transbond XT (3M Unitek®, Monrovia/CA -USA), Group II Orthocem (FGM® Joinville/SC-BR), and Group III Orthobond (Morelli®, Sorocaba/SP-BR). For this purpose, metal brackets were bonded to bovine teeth following the instructions from each manufacturer. The specimens were subjected to a shear test to assess bond strength (BS). Finally, after debonding, the adhesive remnant index (ARI) was estimated.Results:
The average shear strength for a tooth bonded using the adhesive system Transbond XT was 16.39 MPa, while it was 18.08 Mpa for Orthocem and 7.28 Mpa for Orthobond; The Tukey test revealed no statistically significant differences between groups I and II (p < 0.01) and group III differed statistically from groups I and II.Conclusion:
In conclusion, both adhesive systems Transbond XT and Orthocem attained higher bond strength values than Orthobond; the fracture pattern was similar for all adhesive systems applied
