Abstract:
OBJECTIVETo compare the shear bond strength of the fractured anterior teeth reattached by two different adhesive materials.
METHODSForty crown fractured anterior modes were divided into two groups randomly, with 20 in each group. Group A were reattached by Clearfil SE Bond and Clearfil AP-X, while group B were reattached by Clearfil S3 Bond and Clearfil AP-X. Then the specimens were submitted to an axial compression test in a universal testing machine until tooth fractured. The strength was recorded.
RESULTSThe mean shear bond strength of group A and group B was (324.32 +/- 65.91) N and (263.08 +/- 55.88) N, separately. The mean shear bond strength of group A was statistically higher than group B(t = 3.17, P = 0.000).
CONCLUSIONThe shear bond strength of two-step adhesive Clearfil SE Bond is higher than one-step adhesive Clearfil S3 Bond for the reattachment of fractured anterior teeth.
