Aim: The aim of this experimental in vitro study was to evaluate the morphologic and radiographic features of teeth after exposure to an experimental range of high temperatures and to assess the degree of destruction in colour, and crazing of samples. Materials and Methods: the study was conducted to observe macroscopic and radiographic changes in the human teeth the teeth were grouped based on temperature range (200o C 400 oC 600 o C and 800 o C to which its exposed during incineration. Results: Various changes in relation to temperature were observed macroscopically and radio graphically.
