Utility of cheiloscopy, rugoscopy, and dactyloscopy for human identification in a defined cohort

Abstract

Background:Identification is of paramount importance in any forensic investigation. Positive identification of living or deceased using distinctive traits is a cornerstone of forensic science. The uniqueness of these patterns and subtle distinction between traits has offered worthy supplemental tools in establishing the true nature of facts.Aim:The first aim of our study was to determine the most common pattern of lip prints, palatal rugae, and finger prints in the study subjects. Secondly, to determine if any specific pattern of lip print, palatal rugae, or the finger print concurs in individuals, and thereby establish a database of these prototypes for human identification from a defined cohort.Materials and Methods:The sample size comprised 100 female students of a dental college staying together in the hostel. Lip prints were recorded on a white bond sheet using lipstick, palatal rugae on dental casts, and finger prints using printer's blue ink.Results:Our observation suggested that the reticular pattern of lip print, the wavy pattern of palatal rugae, and the loop pattern of finger prints were the predominant patterns. Correlation of the three parameters did not reveal significant differences.Conclusions:This approach of human identification utilizing conventional techniques and relevant parameters is pertinent in defined groups. However, larger representative sample with robust analytical tools may provide a necessary blueprint of human identification.

Estimation of gender using cheiloscopy and dermatoglyphics

“…In our study, the most frequently observed fingerprint pattern was the loop pattern as observed in few studies. [ 1 3 5 9 ] Although males mostly presented whorl fingerprint pattern, females mostly presented loop fingerprint pattern. [ 20 ] Furthermore, arch pattern was the least observed in both the genders in our study which is similar to other studies.…”

“…“Identity” is a set of physical characteristics, functional or psychic, normal or pathological, that defines an individual. [ 3 ] With the ever-increasing demands placed upon law enforcement to provide sufficient physical evidence linking a perpetrator to a crime, it makes sense to utilize any type of physical characteristic to identify a suspect of an offense. There are many well-known implanted methods of human identification such as odontology, anthropometry, fingerprints, cheiloscopy, DNA analysis, and other techniques that determine gender, approximate age, height, etc.…”

Morphological analysis of palatal rugae pattern in central Indian population

“…can be considered to be sources of comparative material because mouth allows for a myriad of possibilities. [6] Identification of an individual is possible which can legitimize the identification process, even in highly difficult circumstances. [7] The palatal rugae pattern will not be modified even in cases of severe illness, chemical injury, or trauma.…”

“…[5] The advantage of palatal rugae is its internal position, which leads to stability and perenity. [36] It is a cost-effective, noninvasive, and easily available mode for human identification.…”
