[Finger and palm prints of children with mild mental retardation].

Studies of the digital and palmar dermatoglyphs in oligophrenic (79 boys and 59 girls) and normal (104 boys and 100 girls) children revealed statistically significant changes in the distribution of the papillary patterns among the fingers: this manifested itself in changed dactyloscopic indices, and increase of the total crest count, and asymmetry of the finger patterns in the oligophrenic children. The main palmar lines were shifted in those children (as compared with the normal ones) to the proximal edge of the palm, and the occurrence of the axial and intermediate triradii changed, this change being statistically significant.
