Gingival RecessionNCT07445555
Gingival Recessions in Orthodontically Treated and Untreated Adult Patients
An observational study of Gingival Recession and Orthodontic Treatment, run by Universitaire Ziekenhuizen KU Leuven at 1 site in Belgium.
Trial summary
To identify the predisposing parameters for gingival recessions in adult patients seeking orthodontic treatment. The ultimate aim is to provide a clinical guideline to estimate the risk of developing post-orthodontic gingival recessions. Read more about this study

About this study
Official title: Gingival Recessions in Orthodontically Treated and Untreated Adult Patients: a Prospective Study
To identify the predisposing parameters for gingival recessions in adult patients seeking orthodontic treatment. The ultimate aim is to provide a clinical guideline to estimate the risk of developing post-orthodontic gingival recessions.
Read the detailed description
The etiology of gingival recessions is yet to be fully understood and is very likely multifactorial, with the involved parameters not necessarily acting simultaneously or in equal extent. The most common etiologic factor would be dental plaque accumulation followed by traumatic tooth brushing, areas with thin, minimal or no keratinized tissue, smoking, malocclusion, dental trauma and high frenal attachment. The labial aspect of the mandibular incisors and maxillary molars is the most often affected by gingival recessions. These contributing factors identified in literature could be grouped in six main categories: age-related, population-related, site-related, mechanical factors, periodontal condition and iatrogenic factors, like orthodontic treatment.
Although quantifying the influence of each factor is very difficult, the association between gingival recessions and orthodontic treatment as an iatrogenic factor has been repeatedly suggested. Given the increasing amount of adult patients seeking orthodontic treatment, the aim of this study is to identify the predisposing parameters for gingival recessions in adult patients, seeking orthodontic treatment. The ultimate aim is to provide a clinical guideline to estimate the risk of developing post-orthodontic gingival recessions.
