[Abnormalities of the masticatory organ in Turner syndrome].

cognition of changes in the masticatory organ in patients with Turner syndrome. The material consisted of 31 girls with this syndrome from age 11 to 23, including 15 with karyotype 45,X, 9 with mosaic karyotype, 2 with structural aberrations of chromosome X and 5 girls with indeterminate karyotype with typical phenotype for Turner syndrome. The investigative methods applied were: extraoral and intraoral orthodontic clinic investigation, pantomographic investigation of dentition, investigation of breadth of dental arches and palatal height on plaster casts of maxilla and mandible with use of the caliper of Korkhaus, and caphalometric examination on teleradiogram of the head. On the basis of the obtained results it has been stated that the typical changes in masticatory organ in patients with Turner syndrome include: the shortening of roots, the hypoplasia of enamel and changes in the shape of teeth's roots and also lateral crossbite. It failed however to confirm, mentioned by other authors, the occurrence of high palate and small, retrogenic mandible.
