Abstract
BackgroundThe relationship between handedness and digital dermatoglyphic patterns has never been investigated in the Sinhalese population. The goal of this study is to establish the above mentioned relationship, which would positively aid personal identification. FindingsOne hundred Sinhalese students (50 right-handed and 50 left-handed) were studied for their digital dermatoglyphic pattern distribution. The results show that a statistically significant correlation exists for digit 3 (P=0.002, Fisher’s exact test) of the right hand and digit 1 (P=0.002, Fisher’s exact test) and digit 2 (P=0.021, Fisher’s exact test) of the left hand. Further, whorl patterns are more common in right-handed than left-handed Sinhalese students.Conclusions Statistically significant differences in handedness and digital dermatoglyphic patterns were evident among Sinhalese people. Further study with a larger sample size is recommended.
