Examinations made of the orofacial region using films located extraorally.
Allows better examination of areas not completely covered by intraoral films, such as, the jaws, skull, or temporomandibular joints (TMJ).
PANORAMIC RADIOGRAPH
Provides a broad view of the jaws, teeth, maxillary sinuses, nasal fossae and TMJs
Shows which teeth are present, its relative state of development, presence or absence of dental abnormalities, and many traumatic and pathologic lesions in bone
Initial examination of choice for completely edentulous (absence of all teeth) patients
LATERAL CEPHALOMETRIC RADIOGRAPH
Also called LATERAL SKULL PROJECTION
It surveys the skull & facial bones for evidence of trauma, disease or developmental abnormality.
It reveals the facial soft tissue profile.
In Orthodontics, it is used to assess facial growth.
In Oral Surgery and Prosthodontics, it establishes pre-treatment and post-treatment records.
TMJ TRANSCRANIAL RADIOGRAPH
Transcranial views provide a reasonably true projection through
the long axis of the temporomandibular joint (TMJ)
