Insights

This study presents a practical diagnostic method for temporomandibular joint (TMJ) disorder using limited cone beam computed tomography (3DX). This approach is ideal for patients with claustrophobia or iodine allergies, offering a safe alternative to MRI and arthrography.

Area of Science:

  • Radiology
  • Medical Imaging
  • Orthodontics

Background:

  • Magnetic Resonance Imaging (MRI) poses challenges due to artifacts and patient incompatibility (claustrophobia).
  • Arthrography is invasive, carrying risks of perforation and contrast medium allergies.
  • Temporomandibular joint (TMJ) disorders require accurate soft tissue imaging.

Observation:

  • A patient with TMJ disorder presented with claustrophobia and an iodine allergy, precluding standard imaging techniques.
  • Limited cone beam computed tomography for dental use (3DX) with air contrast arthrography and pumping manipulation therapy was employed.
  • This novel approach facilitated soft tissue imaging of the TMJ.

Findings:

  • The 3DX examination proved to be a practical and effective diagnostic procedure for TMJ soft tissue imaging.
  • This method successfully circumvented the limitations of MRI and the risks associated with conventional arthrography.
  • The patient tolerated the procedure well, providing valuable diagnostic information.

Implications:

  • The 3DX method is recommended for patients with TMJ disorders who have contraindications to iodine-based contrast agents.
  • This technique offers a viable alternative for claustrophobic patients or those with MRI contraindications.
  • Further research may explore the broader application of 3DX in diagnosing various TMJ-related conditions.

X-ray Imaging01:24

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
Computed Tomography01:10

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
