Apical Periodontitis, MRI, Periodontal Inflammation, Retained Tooth, TMJ
Conditions
Brief summary
The aim of the present study is to show that the use of 0.55T MRI combined with a "dental" coil produces images of sufficient diagnostic value to assess areas of interest in dentistry, and to compare MR images to traditional, dental-oriented radiographic images for diagnostic purposes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Application of a dental-dedicated MRI in the diagnosis of temporomandibular joint disorders, tissue alterations related to third molars, periapical and periodontal inflammatory diseases, and implant treatment planning | 2½ years | Diagnosis of pathologies in the TMJ (e.g. disc displacement (anterior/posterior/lateral), inflammation (yes/no), bone changes (yes/no)), periodontal defects (e.g. bone defects (mm), inflammation (yes/no)), periapical pathology (e.g. inflammation (yes/no), apical periodontitis (yes/no)), bone measurements in edentulous areas, and third molars (e.g. relation to surrounding structures (over/same level/under nerve), resorption of neighboring teeth (yes/no)) seen on MRI compared to diagnosis obtained in radiographs. Observations seen on MRI will be compared to observations seen in radiographs. |
