الملخص	Bone density assessment in dentistry evaluates the quantity and quality of alveolar bone supporting teeth or serving as an implant site. Assessment integrates radiographic imaging (panoramic radiographs, periapical films, and cone-beam computed tomography) and clinical examination to classify bone density into four categories (Type I to IV) and to quantify bone loss. Accurate bone density assessment is critical for implant planning, predicting implant success, and adjusting surgical and loading protocols to account for bone quality variations.	Orthodontic cephalometry is a standardized radiographic technique that produces a lateral or postero-anterior skull radiograph from a fixed source-to-film distance and patient position. Introduced by Benjamin Broadbent in 1931, cephalometric analysis enables systematic measurement of skeletal and dental relationships to assess malocclusion, plan treatment, and monitor growth and treatment changes. The technique remains fundamental to orthodontic diagnosis and treatment planning.
