Study summary

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.

Read the detailed description

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.

Study population

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

  3. Does not have a serious medical condition
  4. Is not pregnant or is not potentially pregnant
  5. Is willing and able to give consent in English
  6. Has the ability to manage their own calendar and schedule appointments
  7. Willing to have a separate 2-hour appointment to have an MRI

Exclusion criteria

Exclusion Criteria:

  1. Unable to consent to participant in English
  2. Serious health condition, which includes but not limited to renal failure/on dialysis, unstable heart disease (uncontrolled arrhythmia, cardiomyopathy and/or unable to lay flat, within 1 month of cardiac catheterization or myocardial infarction), unstable cerebral vascular disease (within 1 month of stroke and/or stent placement), diabetes (type I or II) not controlled by medication or diet, uncontrolled seizures, uncontrolled hyperthyroidism, non-allergic bronchospasm ( and emphysema), uncontrolled movement disorder, and liver failure

Groups and cohorts

  • Dental patients

    Dental patients receiving care that have imaging a part of routine care

    Device: dental-dedicated MRI (ddMRI)

Interventions

  • Devicedental-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.

What researchers measure

Primary outcomes

  1. 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

  2. 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

  3. 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

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 25, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
