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.

Interventions

DIAGNOSTIC_TEST

Tooth mobility assessment

The examiner, holding the instruments (two clinical mirror handles), will apply labial/lingual or labial/palatal displacement movements using the subjective technique, just as routinely done. Using the endodontic spacer and the stop, the deflection will be measured in millimeters. Subsequently, the examiner, with the instruments in hand (tensiometer and dynamometer), will apply labial/lingual and labial/palatal displacement movements, determining the force required to achieve the same displacement previously established by the subjective method (reference/limit of displacement).
