Occlusal morphology in Turner syndrome
European Journal of Orthodontics
|April 1, 1996
Summary
Turner syndrome (45X) patients exhibit a distinct malocclusion pattern, including reduced overbite and increased open bite and crossbite compared to healthy girls. These dental anomalies affect sagittal, vertical, and transversal dimensions.
Area of Science:
- Dentistry
- Genetics
- Pediatrics
Background:
- Turner syndrome (45X) is a genetic condition affecting females, characterized by the absence of one X chromosome.
- Dental malocclusion is a common concern in pediatric populations, with potential impacts on oral health and function.
Purpose of the Study:
- To investigate the prevalence and specific patterns of malocclusion in girls with Turner syndrome.
- To compare the malocclusion characteristics of Turner syndrome patients with a control group of normal girls.
Main Methods:
- A cross-sectional study involving 32 patients with Turner syndrome (ages 7-16.7) and 72 age-matched healthy female controls.
- Dental occlusion was assessed, with analysis stratified by karyotype (45X, mosaic, isochromosome Xq).
Main Results:
- Turner syndrome patients showed a significantly reduced overbite compared to controls.
- Increased prevalence of distal molar occlusion, anterior and lateral open bite, and lateral crossbite was observed in 45X patients.
- Karyotype variations (mosaic, isochromosome Xq) presented similar malocclusion patterns but with greater variability.
Conclusions:
- Patients with Turner syndrome exhibit a specific malocclusion pattern with sagittal, vertical, and transversal deviations.
- X chromosome aberrations are associated with distinct dental anomalies, highlighting the importance of orthodontic evaluation in these patients.
