Radiographic Anatomy Part I Dr. Teodora Gheorghe BSc(Hons), DDS, MSc (Oral Radiology), FRCD(C) [email protected] Part I Attenuation: radiolucent vs radiopaque Review of imaging types Teeth Supporting structures Restorative materials Attenuation Attenuation Radiolucent: Radiopaque: - darker on radiographic images - more white on radiographic images - less dense - more dense - less mineralized - more mineralized Attenuation Radiolucent: Radiopaque: - air - spines - depressions - tubercles - foramina & canals - tuberosities - sutures - prominences - fossae - septa - fissures - teeth - meati - foreign body material Intraoral Images Periapical images - anterior Intraoral images Periapical images - posterior Intraoral images Bitewing images Intraoral images Anterior maxillary occlusal Standard maxillary occlusal Occlusal images Intraoral images Anterior mandibular occlusal Standard mandibular occlusal Occlusal images Extraoral Images Panoramic image Panoramic image – Focal trough White & Pharoah, Oral Radiology – Principles and Interpretation, 2014 Panoramic Image Teeth crown + root enamel dentin pulp chamber root/pulp canal(s) Teeth tooth crown tooth root Teeth enamel dentin Teeth pulp chamber root canal Teeth pulp chamber root canal Supporting Structures trabecular/cancellous bone cortical bone alveolar crest periodontal ligament space lamina dura crestal soft tissues Supporting Structures cancellous/ trabecular bone cortical bone Variation in trabecular bone in different parts of maxilla and mandible Trabecular bone - anterior maxilla Trabeculae & marrow spaces: trabeculae: thin, numerous marrow spaces: small, numerous Cancellous bone pattern: fine Trabecular bone - posterior maxilla Trabeculae & marrow spaces: trabeculae: thin, numerous marrow spaces: numerous, larger than anterior maxilla Cancellous bone pattern: fine Trabecular bone - anterior mandible Trabeculae & marrow spaces: trabeculae: thicker & fewer than maxilla, horizontal marrow spaces: larger than maxilla Cancellous bone pattern: coarser Trabecular bone - posterior mandible Periradicular trabeculae & marrow spaces: trabeculae: usually larger than anterior mandible, horizontal marrow spaces: usually larger than anterior mandible Inferior to teeth: few trabeculae Variations in trabecular bone child adult senior Supporting Structures lamina dura periodontal ligament space periodontal ligament space and lamina dura not as easily discernible on panoramic Supporting Structures alveolar crest Supporting Structures alveolar crest Crestal soft tissue crestal soft tissue Other restorative materials air Air air Restorative Materials amalgam composite Restorative Materials porcelain fused to metal gutta-percha Restorative Materials implants Attenuation - summary Dentin Cementum Metal Composite Enamel Bone Soft tissues Air Radiopaque Radiolucent Corresponding Readings Mallya, S.M., and Lam, E.W.N. 2019.
