Turner’s Syndrome is a representative sex chromosome abnormality in women (designated as 45,X females). These women have a fundamental karyotype of 44 autosomes and a single X chromosome. The purpose of this study was to perform a morphometric analysis of the pulp chambers of the upper and lower molars in 45,X females using orthopantomograms. We examined 40 Finnish 45,X females and 24 of their sisters. The mean age of the 45,X females was 15.6 years and that of their female relatives was 15.3 years. We measured six parameters of the pulp chamber, including the root canals, and calculated six indices using these items. The results of these measurements and indices showed that thepulp height, root length, crown size, and cervical width in the molars of 45,X females were shorter than those in their sisters Conversely, the pulp width in the teeth of 45,X females was expanded in the mesiodistal direction. The upper and lower molars of 45,X females had low and wide pulp chambers.
