Prevalence of the Wire Syndrome

Completed

• Conditions: Orthodontic Wires
• Interventions: Other: no intervention

• Registration Number: NCT06434506
• Lead Sponsor: Centre Hospitalier Universitaire de Nice

Brief Summary

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 Outcome Measures

Name	Time	Method
Prevalence of the Wire Syndrome	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 Outcome Measures

Name	Time	Method
Identify risk factors associated with wire syndrome - clinical examination: overbite / overjet	End : July 2023	Intraoral clinical examinations: overbite and overjet in milimeters
Identify risk factors associated with wire syndrome - questionnaire	End : July 2023	Questionnaire: 20 clinical questions without score
Identify risk factors associated with wire syndrome - clinical examination / description clinical signs	End : July 2023	Intraoral clinical examinations: clinical signs: observations : swallowing and tongue (no score / no mesure : only clinical observations)
Identify risk factors associated with wire syndrome - clinical examination periodontium	End : July 2023	Intraoral clinical examination: type of periodontium: thin and scalloped or flat and thick
Identify risk factors associated with wire syndrome - clinical examination - Angle	End : July 2023	Intraoral clinical examinations: molar and canine relationships according to the Angle's classification class I, class II, Class III
Identify risk factors associated with wire syndrome - clinical examination / presence/absence clinical signs	End : July 2023	Intraoral clinical examinations: presence/absence of an incisal guidance (YES / NO), presence/absence of parafunctions signs, (YES / NO)
