ABSTRACT
Objective To select the indexes of forensic identification in digital orthopantomogram and formulate the full dentition pattern code.Methods To collect randomly 620 samples with dental interventions and 150 samples with dental pathological changes but without therapy.Then to observe and compare them respectively,select indexes for full dentition patterns according to the dental physiological variations,pathological changes and interventions Finally the diversity of the full dentition patterns in two groups would be evaluated by statistical analysis.Results The group with dental interventions had 619 kinds of dental pattern in 620 samples,its diversity of full dentition patterns was 99.84%.The group with dental pathological changes but without therapy had 146 kinds of dental pattern in 150 samples,thus its diversity of full dentition patterns was 97.33%.Conclusion These full dentition pattern indexes were valuable in the forensic identification of persons with abnormal teeth.
