The test was consisting of some objects randomly being placed into the mouth of some individuals to identity its form among three pictures and then the correctness and incorrectness of the questions with the time to present each object to present the first response by an individual was calculated. By the increase of the mental age of the children with Down syndrome, oral stereognosis ability is fixed from 3 to 5 years and the increase of the number of correct identification was not significant (P>0.05). By the increase of mental age from 3 to 5 years, the time spent on stereognosis was reduced significantly (P<0.05). The number of correct identification among the children with Down syndrome was significantly less than healthy control group with the same age (P<0.05).
