An in vitro study was designed to compare the cuspal fracture resistance of intact and endodontically prepared mandibular molars restored with different combination of restorative materials. All specimen teeth were subjected to a compressive load in a Hounsfield Tensometer.
Teeth restored with composite resin after etching and bonding over a glass ionomer pulpal chamber restoration to the pulpal floor level, fractured to a higher compressive load than any other restorative material in the study.
Teeth with MOD cavity preparation restored with amalgam over a composite resin pulp chamber restoration showed the least compressive strength.
