Background and Objectives: To compare the micro shear bond strengths of coronal dentin and pulp chamber dentin using two bonding systems namely Clearfil SE bond and Single bond.
Methods: Thirty molar teeth were collected for the study out of which sixty samples were prepared. Thirty, 2 mm thick slabs of coronal dentin were prepared from each tooth by removing occlusal enamel perpendicular to the long axis of tooth with low speed diamond disc to expose a flat mid coronal dentin and then thirty pulpal floor dentin samples were prepared by sectioning at mid point between floor of pulp chamber and root furcation. These sixty samples were divided into two major groups depending upon dentin location. GROUP I: 30 samples of coronal dentin. GROUP II: 30 samples of dentin at floor of the pulp chamber. Each group was subdivided into two subgroups depending upon the bonding agent used. Subgroup Ia. IIa: Clearfil SE bond. Sub group Ib, IIb: Single bond).
Results: Micro shear bond strength showed higher values to coronal dentin compared to dentin at floor of the pulp chamber and Clearfil SE bond showed higher values compared to Single bond in coronal and dentin at floor of the pulp chamber, but statistically insignificant.
Interpretation and conclusion: Clearfil SE bond showed higher values compared to Single bond in both coronal dentin and dentin at floor of pulp chamber. |
