Dermatoglyphics is a science to determine a pattern both from fingerprints, triradius, tendrils, and the Axial Triradius Digital (ATD) angle. Nowadays, it is can be used in ethnhobiology, forensic or to determine the pattern the disease or disorder. Research on dermatoglyphics is still needs study. Today, research on fingerprint patterns, especially in drug cases is still very limited, so that research is conducted to find out what is the dominance of the fingerprint pattern and ATD angle in people with drug cases.
