Background: Mental retardation means persistently slow learning of basic motor and language skills during childhood and a below normal global intellectual capacity as  an adult. Recently dermatoglyphic patterns have been utilized as a diagnostic tool in various disorders like mental retardation, diabetes mellitus, schizophrenia etc. Present study was undertaken to evaluate the dermatoglyphic features in mental retarded children.

Materials and Methods: The case control study was carried out in 100 mental retarded children and 200 children without mental retardation in the age group between 7 to 15 years. Comparison between the frequencies of finger print pattern of fingers and palms were made out on the basis of two groups in the time employing Chi- Square test.

Result: The dermatoglyphic finding observed in the present study in the mentally retarded children were high frequency of loop and arch patterns and a lower frequency of whorls. Palmar pattern frequency, loops in the third interdigital area, a higher total finger ridge count and absolute finger ridge count, a higher a-b ridge count, higher atd angle, a lower mainline index and  increased frequency of simian crease and Sydney lines.

Conclusion: Dermatoglyphic markers can be used as a screening tool in early detection of mental retardation.
