Abstract

The aim of the study was to evaluate the odontometric characteristics of femaletomale transsexuals FtM in comparison to control groups of males and females A total of 48 FtM aged 20–28 years were studied For each tooth two standard measurements were taken the mesiodistal MD and the buccolingual BL diameter of the crown Significant differences between males and females were found in BL measures of all maxillary teeth as well as mandibular lateral incisor and canine Within the MD measures the most distinguishing were maxillary and mandibular canines and the first molars For seven teeth there were a total of 14 comparisons of MD half for the maxilla and half for the mandible between the control men and women Of these the men had larger diameters for 12 of which four were statistically significant There were also a total of 14 comparisons of BL diameter of these the men had larger diameters for 13 of which nine were statistically significant For seven teeth there were a total of 14 comparisons of MD between the control men and the FtM Of these the men had larger diameters for 12 of which seven were statistically significant There were also 14 comparisons of BL of these the men had larger diameters for 10 of which six were statistically significant For seven teeth there were a total of 14 comparisons of MD between the control women and the FtM Of these the women had larger diameters for nine of which three were statistically significant There were also a total of 14 comparisons of BL of these the FtM had larger diameters for 13 of which five were statistically significant Our study revealed that the shift of values of metric features in teeth of FtM towards males was more frequent in the more sexually dimorphic BL diameters characterized by significantly greater width of the crown of five teeth maxillary canine first and second molars as well as mandibular incisors The results showed intermediate status of femaletomale transsexuals’ teeth between the males and females which may suggest a genetic basis of transsexualism
