Panoramic Radiographic Anatomy - Interactive Lecture_figures/img_193aa7358d317b48.webp) Clinical panoramic radiograph (orthopantomogram) of the dentition. The image displays both maxillary and mandibular arches with mixed dentition, including developing permanent teeth in the posterior regions. A bright horizontal artifact is visible across the mid-face region. An 'L' marker indicating the left side is present in the bottom right corner. **Case 2 - Identify the Teeth using FDI numbers**  Panoramic Radiographic Anatomy - Interactive Lecture_figures/img_fd6ec4ca479ef44d.webp) #### Case 2 - Identify the Teeth using FDI numbers Radiograph showing a panoramic view of the maxillary and mandibular arches with developing permanent teeth.  Panoramic Radiographic Anatomy - Interactive Lecture_figures/img_616a897d2701179f.webp) Labeled panoramic radiograph (orthopantomogram) of the mandible showing seven numbered regions. Region 1 is the condylar head/neck area; region 2 is the coronoid process; region 3 is the ramus; region 4 is the angle of the mandible; region 5 is the body; region 6 is the mental foramen area; and region 7 indicates the symphysis menti. The image includes a title at the top and technical metadata in the bottom right corner.  Panoramic Radiographic Anatomy - Interactive Lecture_figures/img_f7a59a5d6519b849.webp) Labeled panoramic radiograph of the mandible demonstrating anatomical landmarks and pathologies. The image features a title 'Case 4 – Mandibular Anatomy' at the top. Colored annotations include: blue (1), yellow (2), green (3), and red (4) outlining structures in the left maxillary region; purple arrows (5) and orange lines (6) indicating anatomical boundaries or lesions along the mandibular ramus/body; white curved line (7) marking the inferior border; pink oval (8) highlighting a specific feature near the anterior mandible; and light blue arrows (9) pointing to the inferior border of the mandible. # Case 5a – Midface Structures  Panoramic Radiographic Anatomy - Interactive Lecture_figures/img_9b1afe64f9980b40.webp) ##### Case 5a – Midface Structures Labelled panoramic radiograph (OPG) of the maxillofacial region demonstrating midface anatomy. The image features a series of colored outlines and numerical labels superimposed on the bone structure to identify specific anatomical landmarks: Label 1 (green line) indicates the floor of the nasal cavity; Label 2 (yellow lines) points to the lateral nasal wall/cribriform plate area; Label 3 (blue outline) demarcates the maxillary sinus; Label 3a (pink outline) highlights the zygomatic process of the maxilla; Label 3b (blue line) traces the alveolar ridge/maxillary tuberosity; Label 3c (blue line) marks the posterior aspect of the maxilla near the pterygoid plates; Label 4 (orange line) identifies the inferior turbinate or anterior nasal spine region; Label 5 (red outline) outlines the infraorbital rim/orbit; and Label 6 (pink outline) denotes the zygomatic arch. The patient's dentition is visible, including unerupted third molars in both quadrants. Case 5b – **Midface Structures**  Panoramic Radiographic Anatomy - Interactive Lecture_figures/img_4019446e622160d0.webp) ##### Case 5b – Midface Structures Labeled panoramic radiograph of the maxilla and mandible highlighting midface anatomical structures. The image includes color-coded outlines and numerical labels: (1) nasal cavity region, (2) nasal septum, (3) maxillary sinus, (4) floor of the nasal cavity/maxillary sinus interface, (5) zygomatic arch, (6) temporomandibular joint area, and (7) glenoid fossa/condyle region.  Panoramic Radiographic Anatomy - Interactive Lecture_figures/img_015a5b8e8fc75f28.webp) Labeled panoramic radiograph (orthopantomogram) of the maxillofacial region. The image displays the mandible and maxilla with teeth, highlighting peripheral anatomical structures annotated with colored outlines and numbers: 1 (parotid gland), 2 (styloid process/ramus area), 3 (masseter muscle), 4 (temporalis muscle), 5 (cervical spine vertebrae), 6 (mylohyoid muscle), and 7 (anterior belly of digastric muscle). The 'L' marker indicates the left side.  Panoramic Radiographic Anatomy - Interactive Lecture_figures/img_3e63b997e1bc1c2f.webp) A panoramic dental radiograph showing the mandible and maxilla with soft tissue structures annotated. Labels include: 1 (blue) pointing to the nasopharyngeal airway; 2 (red) outlining the right masticator space; 3 (pink) tracing the right submandibular region; 4 (green) indicating the right parotid gland area; and 5 (yellow) highlighting the right cervical lymph node chain. The image includes orientation markers 'R' and 'L' for right and left sides.  Panoramic Radiographic Anatomy - Interactive Lecture_figures/img_b3dc54948d745cd9.webp) Radiograph of the mandible showing dental anatomy with annotations. The image includes a title 'Case 8 – Shadows and Spaces' at the top. Numbered regions are highlighted: (1) pink outline around anterior teeth; (2) red jagged line near molars; (3) blue curved line along upper jaw; (4) green curved line along lower jaw; (5) purple curved line in posterior region. Labels L and CF appear on right side.  Panoramic Radiographic Anatomy - Interactive Lecture_figures/img_371fe1cbd6dce6e0.webp) Labeled panoramic dental radiograph (orthopantomogram) displaying the maxilla and mandible. The image contains numerous numerical callouts identifying anatomical landmarks including: 1-31 for various bone structures (e.g., zygomatic arch, ramus, condyle), teeth (incisors, canines, premolars, molars), sinuses (maxillary, ethmoidal), and soft tissue shadows. Specific numbers like 'R' and 'L' denote right and left sides, while '30' points to the cervical spine region. <img>Dental panoramic X-ray with radiographic landmarks labeled with numbers  Panoramic Radiographic Anatomy - Interactive Lecture_figures/img_c2317bd18902a06e.webp) Dental panoramic X-ray with radiographic landmarks labeled with numbers Labelled dental panoramic radiograph (orthopantomogram) displaying the maxillary and mandibular arches. The image includes numbered callouts pointing to anatomical landmarks such as teeth, mandible, maxilla, temporomandibular joints, and surrounding bone structures.
