PAGD Keystone Explorer Spring 2021

8 www.pagd.org The following is a short list of diagnostic tasks for which 3D imaging is categorically superior to that of 2D (not implying that 3D must be used but when used is superior to 2D): » Dentoalveolar › Localization and extent of periapical/periradicular disease › Third molar relationships to the mandibular canal › Other endodontic applications such as complex root canal anatomy, detection of vertical root fractures, extent of resorptive defects, mandibular canal involvement for lower second molars, etc › Periodontal applications such as detection of buccal/lingual periodontal bone loss, localization of trabecular anomalies, dehiscences, etc › Orthodontic applications such as localization of eruption anomalies, impacted teeth, associated resorptions or eruption obstructions, supernumerary teeth, etc › Implant-related diagnosis and planning › Dental trauma assessment where periapical images provide inadequate information › Hard-tissue pathology assessment (other advanced imaging modalities such as medical CT and MRI should be chosen over CBCT for disease evaluations that are likely to require evaluation to the extent of disease spread into adjacent soft tissues) » Macroskeletal › Morphological assessment of craniofacial anatomy in three dimensions › Diagnosis of skeletal asymmetries › Diagnosis of craniofacial anomalies such as cleft lip and palate
