BACKGROUND: The mandible provides valuable insights into its biological identity. However, the existence of several terminologies for mandibular measurements and inconsistent language can lead to misinterpretation, confusion, and miscommunication. HIGHLIGHT: A standardised set of anatomical points, planes, and measurements would assist with these issues and ensure reproducibility and comparability. CONCLUSION: The proposed coding system offers a comprehensive approach for professionals and researchers in dentistry, archaeology, and anthropology.
