In vitro studies of DNA Recovered from incinerated teeth

Aim To compare the quality of DNA extracted of molars and premolars teeth burned to temperatures between 300°C to 700°C, and provide the initial and detailed knowledge to handle the identification of incinerated bodies by dental DNA. This knowledge is advantageous to avoid delays in the scientific investigation of criminal caseworks. Material and Methods It included sixty-six teeth, upper and lower premolars and molars, of patients under extraction therapeutic, orthodontic treatment or periodontal disease. The samples were divided into six groups randomly, as follows: no burn teeth (control group); teeth incinerated at 300° C, at 400° C, at 500° C, at 600° C and at 700° C. The first group, control, was washed according the described protocol and using Alconox
