Aims: To visualize the surface irregularities and changes after heat treatment on the prosthesis. This was done by Scanning Electron Microscopy. Material and Methods: Eight prosthesis were prepared with modification on the fitting surfaces. The occlusal surface of the tooth to receive the prosthesis was modified and engraved with the initials in the form of identification features. These were heat treated under furnace at temperatures of 500°C, 1000°C and 1500°C after which the scanning was done under Electron Microscope. Results: After heat treatment it was observed that the inner surface of the prosthesis was merely distorted and the details were intact. Analysis of the surface irregularities shows that there are slit surface changes on the occlusal surface at 1000°C and the fitting surface details are well protected. Conclusion: It was identified that after heat treatment at temperatures 1000°C and above some changes started occurring on the fitting surface and the identification features. At these temperatures the whole human body is charred and even the bones start to get destroyed. SEM images give the detailed pictures of the same and that if this method is incorporated in day today dentistry it will be a boom in the forensic identification.
