A comparison of the bond strengths of two different dentine-bonding agents to bone.
OBJECTIVE
This study was performed to test the bond strength obtained between composite and bone using two different dentine-bonding agents.


METHODS
P50 composite was bonded to 60 specimens of pig calvarium using All bond 2 (Bisco, Itaska, IL) or A.R.T. bond (Coltene, Altstatten, Switzerland) dentine-bonding agents. The bonds were tested to failure in an Instron Universal Testing machine (High Wycombe, UK) and the bond strength calculated. Data were analysed using the Weibull distribution.


RESULTS
All-bond 2 and A.R.T. bond produced mean bond strengths of 8.5 MPa and 8.4 MPa, respectively, in the model used. The Weibull moduli were 2.4 and 2.1, respectively.


CONCLUSIONS
There was no significant difference in the performance of the adhesives tested when used to bond composite to bone. The bond strengths obtained give rise to some optimism over the possible use of these systems in bone fracture fixation.
