[Shear bond strengths of four types of adhesive resin agents to GI II glass infiltrated ceramic].
OBJECTIVE
The shear bond strength of four adhesive resins bonded to GI II glass infiltrated alumina ceramic was investigated in this experiment.


METHODS
A total of 40 ceramic blocks and 40 tooth blocks were prepared and divided into 4 experimental groups, including group A (CereDual and silicoating), group B (Calibra and silicoating), group C (Panavia) and group D (Super C&B and silicoating). The shear strength of four different bonding systems to dentin was tested respectively. The data were statistically analyzed.


RESULTS
More than 13 MPa of bonding strength was achieved using the traditional Bis GMA bonding resin (groups A and B), and more than 16 MPa was obtained using the improved Bis GMA bonding resin (group C and D). There was statistical difference between groups A, B and group C, D.


CONCLUSIONS
It can be implied that an ideal bonding can be obtained by using different bonding materials and processing the dentin surface with the suitable conditioner.
