Summary
Magnetic resonance imaging (MRI) is a feasible method for precisely locating impacted teeth in three dimensions. This non-invasive technique offers clear visualization and avoids ionizing radiation, benefiting pediatric patients.
Area of Science:
- Dentistry
- Radiology
- Medical Imaging
Background:
- Impacted teeth are embedded in jawbone beyond normal eruption.
- They pose risks of infection and damage to adjacent teeth.
- Accurate 3D localization is crucial for orthodontic diagnosis and treatment planning.
Purpose of the Study:
- To evaluate the feasibility of using magnetic resonance imaging (MRI) for 3D localization of impacted teeth.
- To assess MRI's effectiveness in pediatric and adult patients.
Main Methods:
- Prospective study involving 39 pediatric patients and 7 adult patients with impacted teeth.
- Utilized magnetic resonance imaging (MRI) for imaging.
Main Results:
- MRI provided clear separation between impacted teeth and surrounding tissues.
- Accurate assessment of impacted tooth position and angulation in all three spatial dimensions was achieved.
- Demonstrated advantages over conventional radiography, including volumetric data and no ionizing radiation.
Conclusions:
- Dental MRI is a feasible and advantageous tool for the 3D localization of impacted teeth.
- Its non-ionizing nature is particularly beneficial for pediatric patients requiring repeated imaging.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
