Abstract

Aim and Objectives: The purpose of this study were to (1)compare the shear peel bond strength of four different orthodontic banding cements (2) assess the site of cement failure after debanding (3) compare the survival time of the bands cemented with each cement type after simulating mechanical fatigue stress.
Materials and Methods: Eighty teeth were used to assess retentive strength and another forty teeth were used to assess the fatigue survival time. Shear peel bond strength was determined with a universal testing machine. Fatigue testing was conducted in a ball mill machine.
Results: The mean shear peel bond strength and survival time of the bands cemented with GC Fuji Ortho band paste pak was significantly greater among all the groups.
Conclusion: Bond failure occurred predominantly at the enamel-cement interface. GC Fuji ortho band paste pak orthodontic banding cement required significantly higher forces to deband in comparison with the other cements. GC Fuji ortho band paste pak orthodontic banding cement can be expected to have lower failure rates for band cementation than the other groups in the light of the results of the ball mill test.
