Lesson 1Plain radiography: indications and interpretation of panoramic radiograph (OPG) for jaw pathologyThis section focuses on panoramic radiography for jaw assessment, reviewing indications, patient positioning, normal anatomy, and interpretation of common pathologies, while highlighting limitations and when further cross-sectional imaging is required.
