Reproducibility of mandibular landmarks for three-dimensional assessment

Abstract

Mandible can be an elective bone for human identification. This study aimed to test the reproducibility of \nmandibular landmarks in three-dimensional reconstructions. Cone-beam computed tomography of 17 patients from \n7 to 20 years were collected at University of Coimbra database and reconstructed in Mimics Innovation Suite 17.0. \nTwenty-five landmarks were demarcated for thirty measurements. Reproducibility was evaluated with Intraclass \nCorrelation Coefficient (ICC) for intra-examiner agreement and Technical Error of Measurement (TEM) for interexaminer \nerror, with P < 0.05. Excellent intra-examiner agreements and acceptable inter-examiner errors were \nfound for variables. The reproducibility was confirmed, validating its applicability in forensic purposes.
