Tooth Crown Morphology in Turner and Klinefelter Syndrome Individuals from a Croatian Sample.

Objective: Turner syndrome (TS) and Klinefelter syndrome (KS) represent the two most common X chromosome aneuploidies, each associated with systemic disruptions to growth and development. Effects of these conditions on tooth crown morphology are explored in a sample of Croatian individuals.

Materials And Methods: The sample included 57 TS, 37 KS and 88 control individuals.

Occlusal molar surfaces in females with Turner's syndrome.

The aim of this study was to identify the molar occlusal features in 73 subjects with the Turner's syndrome (TS) and compared to a control group (CG) of 322 healthy females. The occlusal features were scored on dental plaster casts using the Scoring Procedures for Key Morphological Traits of the Permanent Dentition: The Arizona State University Dental Anthropology System (ASU). The results were analyzed through frequency, percentage and chi 2-test.

Occlusal plane orientation in Klinefelter syndrome (47,XXY males).

Occlusal plane position was analysed cephalometrically in 35 Klinefelter adults (47,XXY) and compared with 60 eugnath control males (46,XY). The significantly smaller angles between the occlusal plane and the cranial base (NSL-OLs) and between the occlusal plane and the Frankfort horizontal plane (Fr-OLs) were obtained in 47,XXY males (P < 0.01), while the angles between the maxillary base and the occlusal plane (NL-OLs) and between the Camper's line and the occlusal plane (Camp.

Shape of the craniofacial complex in patients with Klinefelter syndrome.

The shape and size of the craniofacial complex in 35 adults with Klinefelter syndrome (47,XXY) were analyzed cephalometrically and compared with 60 control males. Twenty-four angular and 18 linear measurements were obtained for each subject. The results showed that the 47,XXY males were different from the controls in several areas of the craniofacial skeleton.
