ABSTRACT
Objective:
To compare the bonding strength of 3M Adper Easy One(3AEO),Clearfil S3 Bond(CSB)and Super-Bond C&B(SBCB)in vertical tooth fracture mode.Methods:
30 freshly extracted human molars were randomly assigned to three groups(n =10).The teeth were cut along the long axis with low speed cutting machine and were prepared into a unified model of the vertical tooth fracture.The three adhesives were respectively used to adjoin the surface of the fractured teeth.The samples were subjected to thermal cycling for 500 cycles,stored in distilled water at 37 ℃ for 24 h.Then the pillar-like specimens with the bonding area of 1.0 mm × 1.0 mm were prepared.The microtensile bond strength was measured and the fracture mode was observed.Results:
The bond strength (MPa)of 3AEO,CSB and SBCB was 18.57 ±4.98,16.93 ±4.70 and 22.75 ±5.18 respectively(P 0.05).Conclusion:
The surface bonding of Super-Bond C&B in tooth fracture is stronger than 3MAdper Easy One and Clearfil S3 Bond.
