Resistance to Tooth Fracture with Different Restorative Material | |
Geeta Sharma, Randhir Kumar | |
Background: Dental caries causes irreversible damage to the tooth. Different restorative materials are used to restore the tooth. Aim: To evaluate the resistance to tooth fracture with different restorative material cast gold, silver amalgam and composite.Material & method: An in vitro study was carried out on thirty two freshly extracted human mandibular first molar to investigate the effect of different restorative materials on the resistance of remaining tooth structure to fracture.The amount of load required to fracture the experimental sample was assessed against the control sample using Hounsfield tensometer.Result: Cast gold offers maximum resistance and silver amalgam provides least resistance. Conclusion: All restorative materials included in this study exhibited some degree of resistance to tooth fracture. Cast gold offers maximum resistance in comparison to unrestored specimens and those restored with either silver amalgam or composite. Composite fall in between cast gold and amalgam restoration.
