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

University of Aarhus470 enrolled

Overview

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.

Outcomes

Primary Outcomes

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.
