Abstract

CONTEXT:

Cheiloscopy and dactyloscopy, both are well-established forensic tools used in individual identification in any scenario be it a crime scene or civil cause. Like finger prints, lip prints are unique and distinguishable for every individual. But their relationship to personality types has not been established excepting the hypothesis stating that finger prints could explain these personality patterns.

AIMS:

The study was aimed to record and correlate the lip and finger prints with that of character/personality of a person.

SETTINGS AND DESIGN:

The lip and finger prints and character of a person were recorded and the data obtained was subjected for statistical analysis, especially for Pearson's Chi-square test and correlation/association between the groups was also studied.

MATERIALS AND METHODS:

The study sample comprised of 200 subjects, 100 males and 100 females, aged between 18 and 30 years. For recording lip prints, brown/pink-colored lipstick was applied on the lips and the subjects were asked to spread uniformly over the lips. Lip prints were traced in the normal rest position on a plain white bond paper. For recording the finger prints, imprints of the fingers were taken on a plain white bond paper using ink pad. The collected prints were visualized using magnifying lens. To record the character of person, a pro forma manual for multivariable personality inventory by Dr. BC Muthayya was used.

STATISTICAL ANALYSIS USED:

Data obtained was subjected for statistical analysis, especially for Pearson's Chi-square test and correlation/association between the groups was also studied.

RESULTS:

In males, predominant lip pattern recorded was Type I with whorls-type finger pattern and the character being ego ideal, pessimism, introvert, and dogmatic; whereas in females, predominant lip pattern recorded was Type II with loops-type finger pattern and the character being neurotic, need achievers, and dominant.

CONCLUSION:

Many studies on lip pattern, finger pattern, palatal rugae, etc., for individual identification and gender determination exist, but correlative studies are scanty. This is the first study done on correlating patterns, that is, lip and finger pattern with the character of a person. With this study we conclude that this correlation can be used as an adjunct in the investigatory process in forensic sciences.
