Prevalence of the Wire Syndrome

The Wire Syndrome problem referred to dental displacements that can be described as aberrant, inaccurate, unexplained, or excessive on teeth still contained by an intact orthodontic wire, without detachment or fracture, leading to evolving dental and periodontal, aesthetic and/or functional consequences. The objective of this study was to define the prevalence of mandibular wire syndrome and the associated risk factors.

Primary outcomes

  1. Prevalence of the Wire Syndrome

    Time frame: End : July 2023

    The prevalence of wire syndrome is the number of people affected by the wire syndrome at a given time in a given population. The prevalence rate is calculated by dividing this number of cases by the size of the exposed population. This study was design as a cross-sectional study conducted in the Orthodontics Unit of the Nice University Hospital from July 2022 to July 2023.

Secondary outcomes

  1. Identify risk factors associated with wire syndrome - questionnaire

    Time frame: End : July 2023

    Questionnaire: 20 clinical questions without score

  2. Identify risk factors associated with wire syndrome - clinical examination periodontium

    Time frame: End : July 2023

    Intraoral clinical examination:

    type of periodontium: thin and scalloped or flat and thick

  3. Identify risk factors associated with wire syndrome - clinical examination - Angle

    Time frame: End : July 2023

    Intraoral clinical examinations:

    molar and canine relationships according to the Angle's classification class I, class II, Class III

  4. Identify risk factors associated with wire syndrome - clinical examination: overbite / overjet

    Time frame: End : July 2023

    Intraoral clinical examinations:

    overbite and overjet in milimeters

  5. Identify risk factors associated with wire syndrome - clinical examination / presence/absence clinical signs

    Time frame: End : July 2023

    Intraoral clinical examinations:

    presence/absence of an incisal guidance (YES / NO), presence/absence of parafunctions signs, (YES / NO)

  6. Identify risk factors associated with wire syndrome - clinical examination / description clinical signs

    Time frame: End : July 2023

    Intraoral clinical examinations:

    clinical signs: observations : swallowing and tongue (no score / no mesure : only clinical observations)
