Method for Measuring Dental Mobility and Displacement Force

Brazil20 participantsStarted 2024-08-10

Plain-language summary

This study aims to investigate the use of a new method for measuring tooth mobility, which includes control of force (gf) and labial/lingual/palatal displacement (mm) of upper and lower incisors with tooth mobility. It will take place during a single assessment session at the clinic of the Piracicaba Dental School (FOP-Unicamp), supervised by the research student Larissa Alexandra Fatinanzi and Prof. Dr. Enílson Antônio Sallum. The evaluation will be conducted in person during regular clinical appointments, without requiring additional travel or extended time beyond what is planned. The research will be conducted over two different days of appointments, scheduled on the same day and time as regular clinical appointments, occupying 30 minutes to 1 hour each. Day 1: A molding (copy of the tooth) will be performed. Based on this step, a customized instrument will be made (necessary for evaluating the tooth with mobility). Customized Instrument: The materials used will include: acetate plate (similar to a teeth whitening tray); endodontic spacer (used in root canal treatment); tensiometer and dynamometer (used in orthodontics to measure force); and caliper (a device for measuring in millimeters). Day 2: Evaluations will be conducted, including mobility (tooth with movement), periodontal parameters (examination of the gums and tooth support system), and completion of a questionnaire with basic questions relating daily life to the clinical situation (tooth with movement). The assessment of dental mobility involves moving the tooth forward and backward, similar to routine clinical practice. The amount of tooth movement will be measured in millimeters using the customized instrument. Additionally, a tensiometer and dynamometer will be used to measure the force. The force applied by the instruments will not harm the tooth with mobility. Two sets of dental mobility tests will be performed, with a 1-minute interval between them. The instruments used pose no risk to oral tissues, are employed in dental treatments, and are non-invasive. All evaluations will be carried out on the same day of the appointment.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients diagnosed with Periodontitis Stage II, III, and IV (grades A, B,C) and with periodontal pockets ≥ 4 mm. * Anterior teeth (13-23 and 33-43) with dental mobility (grade 1, 2, or 3). * Aged ≥ 18 years. Exclusion Criteria: * Crossbite or end-to-end bite. * Bruxism. * Implants adjacent to the tooth with mobility. * Extreme mobility. * Occlusal trauma. * Patients requiring prophylactic antibiotics.

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.
