Periodontal Status in Patients With Oral Lichen Planus
176 participantsStarted 2026-05-20
Plain-language summary
This case-control study will enroll 176 patients age- and sex- matched at the Oral Medicine Unit, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome. There will be two groups: The control group will consist of 88 healthy patients enrolled among those routinely attending the dental outpatient clinic. An additional 88 patients diagnosed with OLP will form the case group. Both groups will undergo standard dental examinations, including periodontal probing. The primary objective is to evaluate whether patients with OLP present a higher prevalence and severity of periodontitis compared to healthy subjects. Secondary objectives include the assessment of gingivitis prevalence and RT1 gingival recessions in OLP patients compared with controls. Periodontal status will be assessed using major clinical indices and classified according to the 2017 AAP/EFP case definition. The study aims to contribute evidence on the shared immune-inflammatory mechanisms underlying both conditions, with potential clinical implications for the integrated periodontal management of OLP patients.

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?
