Tuberculosis is one of the major health problems in developing countries. The aim of present study was to find out differences in dermatoglyphic patterns between diagnosed pulmonary tuberculosis patients and normal healthy persons and to determine the usefulness of dermatoglyphics in studying genetic susceptibility to pulmonary tuberculosis. The sample constituted 100 diagnosed pulmonary tuberculosis patients (cases) and 100 unrelated healthy subjects (controls). Dermatoglyphic patterns studied were total finger ridge count (TFRC), absolute finger ridge count (AFRC), __ampersandsignlsquo;atd__ampersandsignrsquo; angle and finger tip patterns.The statistical analysis of data showed significant increase in total finger ridge count (TFRC) and absolute finger ridge count (AFRC) in both hands of pulmonary tuberculosis cases as compared to controls. The __ampersandsignlsquo;atd__ampersandsignrsquo; angle in both hands of pulmonary tuberculosis cases was lower than controls and that difference was statistically significant. This indicates that the axial triradius was placed proximally in both hands of pulmonary tuberculosis cases than in controls. There were no statistically significant differences observed in fingertip patterns among pulmonary tuberculosis cases and controls.
