Comparative evaluation of the regional micro push-out bond strength of pre-fabricated resin post system using various self-etch adhesive systems: An in vitro study

AUTHOR(S): Randhya, Velmurugan N and Karthik L
ABSTRACT:Aim: The purpose of this study was to evaluate the micro push out bond strength of a pre-fabricated fiber post luted with various self-etch adhesive cements at cervical, middle and apical thirds of the post space region.
Methods: Thirty freshly extracted human maxillary central incisors were selected for the present study. After preparation, each specimen was embedded in chemically cured acrylic resin and were randomly assigned to three groups: A, B and C. Each root was sectioned perpendicular to the long axis using a microtome and subjected to micro-push-out bond strength.
Results: Among the 3 groups tested, the cervical region demonstrated significantly higher bond strength values of 20.6 ± 6.2 MPa (Group A), 24.7 ± 2.7 MPa (Group B) and 39.6 ± 7.2 MPa (Group C).
Conclusion: Push-out bond strength values were higher in cervical region followed by middle third and least strength was seen in apical third of post space region.
