摘 要：Background:To evaluate morphologic,radiographic,and stereomicroscopic changes of teeth when subjected to specific high temperatures in both direct heat and gradual heat and to compare the changes among two heat groups and also among different types of *** and Methods:An in vitro study was conducted on 90 healthy extracted human teeth,in which the teeth were divided into two *** 1(45)was subjected to direct heat and Group 2(45)was subjected to gradual *** 1 and Group 2 were further subdivided into three subgroups(A)anteriors,(B)premolars,and(C)molars each consisting of 15 *** were subjected to temperatures of 200°C,400°C,600°C,800°C,and 1000°C in a muffle electric *** color changes were noted using the Revised Munsell soil color chart and the radiographic and stereomicroscopic changes were *** results obtained were subjected to statistical ***:Teeth in direct heat showed more destructive changes at lower temperatures,i.e.,400°C and 600°C when compared to gradual heat where changes are observed at 600°C and 800°*** different types of teeth,anteriors and premolars showed more changes when compared to *** and Conclusion:It can be concluded that dental evidence may provide clues to solve the mystery in fire investigations as dental structures are the last to be destroyed under extreme conditions,whether temperature,acid,or putrefaction.
