An observational study in Dental Crowding, Dental Occlusion, Traumatic and Endodontic Disease, sponsored by University of Minnesota. Recruiting at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-08-25.
Sponsored by University of Minnesota · Observational
This description observational research is comparative in design, that is comparing existing standard clinical dental images, not obtained in this study, to test (i.e., ddMRI) images. The standard clinical dental images consist of radiographs, such as bitewings, periapical, panoramic, cone-beam CT, and medical CT, as well medical MRIs of the temporomandibular joints (TMJ).The conceptualization of research questions, study designing, and interpretation of imaging data has and will involve content expertise in all ddMRI research.
Patients of record will be recruited from dental clinics at the University of Minnesota School of Dentistry will be screened for eligibility and asked to complete an MRI safety screening questionnaire. Eligible individuals will be invited to participate in at least one study visit, during which an MRI scan will be performed.
88 studies on the registry are indexed under Crowding; 22 are open to participants now.
This study's planned enrollment of 500 is below the median of 664 across 14 observational studies indexed under Crowding.

Univeristy of Minnesota School of Dentistry School patients age 18 and older that are able to provide informed consent for themselves who are established patients and being treated in a specialty clinic, such as Endodontics, Orthodontics, Periodontics, Oral Surgery, or the TMD Oral/Facial Pain Clinic for routine dental care where diagnostic imaging is current within the last 3-5 years.

Device: dental-dedicated MRI (ddMRI)
This descriptive observational research is comparative in design, that is comparing existing standard clinical dental images, not obtained in this study, to test (i.e., ddMRI) images.
Feasibility and Safety Assessment of ddMRI in Dental Patients
Evaluate the feasibility and safety of dental-dedicated MRI (ddMRI) in dental patients by assessing their experiences immediately following each scan. This will be done using an exit questionnaire designed to capture any sensations or discomfort that may have occurred during the scan. Participants will be asked to report the presence of various sensations, including but not limited to: nervousness, double vision, sleepiness, vertigo, lightheadedness, metallic taste, and feelings of warmth or cold. The collected responses will help determine the overall tolerability of ddMRI in this patient population.
Time frame: 1 year
Diagnostic Quality Assessment of ddMRI in Dental Patients
The diagnostic quality of dental-dedicated MRI (ddMRI) in dental patients will be evaluated through subjective ratings of its ability to identify various dentoalveolar anatomical structures. These ratings will be compared to those obtained from existing standard dental imaging modalities. Additionally, intra- and inter-rater reliability analyses will be conducted to assess the consistency of the ddMRI interpretations and their agreement with conventional dental imaging.
Time frame: 1 year
Anatomical landmark identification and inflammation detection
Compare the diagnostic efficacy of ddMRI versus existing clinical imaging (e.g., plain film, CT, MRI) in terms of identifying anatomical landmarks and detecting the presence of inflammation, as rated by dental specialist examiners.
Time frame: 3 years
