A Study of Relative Correlation Between the Pattern of Finger Prints and Lip Prints

Abstract

BACKGROUND AND OBJECTIVE: The use of conventional methods such as dactylography (study of finger prints) & cheiloscopy (study of lip prints) is of paramount importance, since personal identification by other means such as DNA analysis is sophisticated and not available in rural and developing countries. Fingerprint in its narrow sense is an impression left by the friction ridges of human fingers. The second prints of interest are lip prints. Studies of association between finger print and lip prints are scanty in literature. The present study was aimed to analyze the predominant pattern of lip and finger prints and to identify whether there is any correlation between these two parameters. MATERIALS AND METHODS: The study sample included 300 college students. Brown/pink colored lip stick was applied on the lips and the subject was asked to spread it uniformly over the lips by gentle movement of the lips. The unglazed white paper was then pressed uniformly over the lips. After the fingers were cleaned with tissue paper, the subjects were instructed to roll the tip of their fingers across the surface of an already made ink-stained pad, ensuring that the ink covered the entire pattern area. The inked finger was then enrolled over a white paper to obtain the print and analyzed using magnified hand lens. These prints were examined using magnifying glass, classified, and analyzed. The data was statistically analyzed by using Chi-square test. RESULTS: The percentage distribution of lip print shows that the most frequent lip print pattern in the male is Type I (36.8%) and in female it is type II (34.4%). There is no statistically significant association between the pattern of finger prints and lip prints (p value = 0.9). CONCLUSION: It is known that individual parameters, i.e., lip print and finger print patterns play an important role in forensic identification. Correlation of these two parameters in our study did not show any significant association, hence, these combinations as such cannot be used in individual identification, but rather, they can be used to substantiate facts in crimes where there are few evidences

Lip Prints Analysis: An Observational Study

“…If more than one pattern predominates it is taken as undetermined (type 5). In the present study type 2 is found to be dominant in females which is in accordance with a similar study done by Neha bansal, et al in a study sample of 2500 females and 2500 males stated that Type I, I', II lip print pattern was most predominant in females [32]. It is found in the study that lip prints are unique to each individual and a similar study done by Amrita, et al in a study sample of 200 medical students also stated the same [33].…”

Correlation of Blood Group, Cheiloscopy, Dactylographic Pattern Among Physiotherapy Tribal Student in Chhattisgarh.

“…Blood group, students obtained ABO process and each students bio data, cleiloscopy and dactylographic pattern were recorded, apply lipstick and glued portion of the cellophane tape was used to obtain the impression of the lip, immediately transferred onto paper by gently sticking the cellophane tape and analysis, each cheiloscopy was divided into six types, cheiloscopy classificated according to Suzuki and Tsuchihashi 13 , Type -I Clear cut grooves running vertically across the lip, Type -I' The grooves are straight but they disappear half way, Type -II The grooves fork in their way(branched), Type -III The grooves intersect, intersecting, Type -IV The grooves are reticular, reticular, Type -V The grooves do not fall in any of the types from I to IV, undetermined. Dactylographic pattern, imprint of both hands fingers was taken, pattern was examined by using magnifying glass, dactylographic pattern were classified according to Michael's and Kucken's 14 . Loop, Whorl, Arch, Composite containing two or more forms.…”
