Objectives : to study the possible correlation between the fractures toughness of different luting cements with their tensile peel strength.
Methods : Six cements were investigated; two chemically adhesive resin cements (Super-Bond C&B and Panavia 21), one compomer cement (Dyract Cem), two resin-modified glass ionomer cements (Fuji Plus and RelyX Luting), and one conventional glass ionomer cement (Ketac Cem).
The tensile peel strength was investigated by bonding grit-blasted Ni / Cr alloy beams to a block of the same alloy using the different types of luting cements (n = 20 for each cement), leaving half the length of the beam free.
Beams were pulled off the block with a peeling action by applying a tensile load to the free end of the beam and load at failure point recorded.
The values of the tensile peel strength were compared with the known fracture toughness values of these cements from the dental literature that were measured after 24 hours and after seven days.
Results : direct relationship was found between the fracture toughness of the luting cements and their tensile peel strength.
The linear regression analysis showed that the correlation coefficient (r) is equal to 0.94 and 0.98 when compared with 24 hours and 7days fracture toughness data respectively.
Conclusion : Luting cement with higher fracture toughness has higher tensile peel strength and thus better potential for retention of resin bonded bridge.
