|
| The purpose of this research is to study the relationship between Carabelli's trait and tooth crown size in
45,X females and to clarify the effect of the shortage of X chromosome to the dental crown. The subjects comprised eighty one 45,X
females in the Kvantti research collection and Finnish female controls. Dahlberg's reference plaque (1956) was used to determine the
score of the Carahelli's trait which was divided into three classes. The scores were compared with the maximum mesiodistal and buccolingual
tooth crown diameters. The result showed that the mesiodistal diameters in 45,X females were significantly smaller than control females, while
no association was found between Carabelli's trait and buccolingual tooth crown diameter in 45,X females. Mesiodistal tooth crown diameter
was thought to he a key factor to develop the Carabelli's trait in 45,X females.
Keywords: Carabelli's trait, 45,X females, Turner's syndrome, tooth crown size. |
