This document provides anatomical landmarks to identify on a radiograph of the head and neck region. It lists structures like the lamina dura, periodontal ligament space, trabecular and interdental bone, alveolar crest, inter-maxillary suture, anterior nasal spine, nasal septum, incisive foramen, nasal cavity, zygomatic bone, maxillary sinus, pterygoid plate, mandibular symphysis, genial tubercle, mental ridge, lingual foramen, mental foramen, mandibular canal, nutrient canals, mylohyoid ridge, external oblique ridge, and coronoid process. The purpose is to teach practitioners how to identify
