MRI as Alternative to CBCT for the Assessment of Furcation Involvement in Molars

Austria140 participantsStarted 2023-11-20

Plain-language summary

Aim of this prospective study is to compare magnetic resonance imaging (MRI) and cone beam computed tomography (CBCT) to diagnose furcation involvement (FI) in molars in patients with periodontitis. The focus is on the differentiation of grad II and III according to Hamp et al. 1975. 140 molars (70 upper and 70 lower) will be investigated with CBCT and MRI. Due to the absence of ionic radiation MRI might be a radiation free diagnostic tool to assess FI in the future without harmful radiation for the patient. Patients of the Dental Clinic, Medical University of Vienna, who need a CBCT and have a clinically diagnosed FI can be a participant of this clinical trial and do in addition to their CBCT a MRI. The accuracy of MRI will be compared to the diagnostic gold standard CBCT. If patients need additional periodontal treatment, e.g., periodontal surgery, a subgroup will also be analysed with intraoperative measurements.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
