Sažetak

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
2-test. TS subjects have more frequent reduction of cusp number,
distolingual cusp on the upper molars and distal cusp on the lower molar, with the
consequent reduction of the occlusal surface. Reduced size of occlusal surface and number
cusps on upper molars resulted in the transformation of rhomboid occlusal shape
into triangular, with the consequent loss of H-shaped groove system (in the upper right
first molars H-shaped groove system was significantly less frequently found in TS (p<
0.05); in the upper left second molars H-shaped groove system was significantly less frequently
found in TS (p<0.01). The X-chromosome aneuploidy can cause a decrease in
developmental homeostasis, which results in the alteration of apposition of the enamel
and in consequently substantial changes of the molar occlusal morphological features.
