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.
referred for CBCT imaging of at least one tooth for endodontic reasons
referred for intra-oral and/or panoramic imaging covering at least one molar tooth for periodontal reasons
referred for CBCT imaging of the TMJ (bilaterally)
referred for panoramic imaging of the third molar (retained/semi-retained, uni- or bilateral), prior to treatment planning
younger than 18 years
unable to give consent
pregnant
pronounced claustrophobia
Single group
MRI of teeth and surrounding structures
Deviceincluded above
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
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.
