What are the benefits of extraoral radiography over intraoral radiography?
Extraoral radiography provides a broader view of the jaw and skull, assisting in the evaluation of larger anatomical structures and detecting pathological conditions or developmental abnormalities. It is less invasive, reduces patient discomfort, and is useful for patients who have a gag reflex or difficulties with intraoral films.
How is extraoral radiography used in orthodontics?
Extraoral radiography in orthodontics is used to assess jaw relationships, growth patterns, and the alignment of teeth. It provides crucial insights for diagnosing malocclusions and planning treatment. Common techniques include panoramic and cephalometric imaging, which help in developing precise orthodontic treatment plans.
Is extraoral radiography safe during pregnancy?
Extraoral radiography is generally considered safe during pregnancy when appropriate safety measures, such as lead aprons and minimizing exposure, are in place. It is advisable to inform the dental professional about the pregnancy so they can take necessary precautions to minimize radiation exposure.
What types of conditions can extraoral radiography help diagnose?
Extraoral radiography can help diagnose conditions such as temporomandibular joint disorders, jaw fractures, facial trauma, impacted teeth, sinus problems, tumors or cysts in the jaw, and developmental anomalies in the skull and facial bones.
What is the difference between extraoral radiography and panoramic radiography?
Extraoral radiography refers to any radiographic imaging done with the x-ray source outside the mouth, encompassing various techniques. Panoramic radiography is a specific type of extraoral radiography that captures the entire dentition, jaws, and surrounding structures in a single image.
