In children with congenital anomalies, minor anomalies may often occur in the oral regions.
This is more so in children with the Down syndrome.
It has been said that one of its characteristic tooth anomalies is a microdont.
However, only little is known about tooth size except for the malformation ones in children with Down syndrome during the deciduous tooth stage.
In this study, the authors measured the mesiodistal and bucco lingual distances in a group of 28 children with the Down syndrome during the deciduous stage, and compared it with in the group of 94 normal children at the same stage.
The foiling results were obtained.
(1) In the measurements of the upper anterior and posterior teeth, it was noted that the buccolingual distance was shorter, and the mesiodistal was longer in children with Down syndrome as compared with normal children.
(2) In the measurements of the lower anterior and posterior teeth, a slight tendency similar to those of the upper teeth, was observed but no marked difference was noted in children with the Down syndrome as compared with normal children.
