Lip outline: A new paradigm in forensic sciences

Abstract

Introduction:Personal identification is becoming increasingly important not only in legal medicine but also in crime/criminal investigation and identification. Sometimes establishing a person's identity can be a very difficult process. Dental, fingerprint, and DNA comparisons are probably the most common technique used. However, there are many well-known implanted methods of human identification, one of the most interesting emerging methods of human identification which originates from the criminal and forensic practice, is human lips recognition. Cheiloscopy is a forensic investigation technique that deals with the identification based on lip traces. The lip outline of every person is unique and can be used to fix the personal identity.Aim:The aim of this study was to assess the distribution of lip outline patterns among males and females, and to evaluate the uniqueness of lip outline pattern.Materials and Methods:The study group comprised of 200 individuals from Kamineni Institute of Dental Sciences. Lip outline patterns were obtained and were transferred to the proforma sheet for analysis.Results:The results of the study revealed that the lip outline patterns for each individual were unique.Conclusion:This study showed that lip outline patterns are unique to each individual and can be used for personal identification.

A Queiloscopia como técnica de identificação humana: Uma revisão sistemática da literatura

“…Dentre os aspectos da unicidade, as impressões labiais são diferentes entre si, assim como diferentes entre os indivíduos, mesmo que estes sejam gêmeos (Suzuki & Tsuchiahashi, 1971;Molano et al 2002;Barros, 2006;Caldas et al, 2007;Sharma et al, 2009;El Domiaty et al, 2010;Costa & Caldas, 2012;Karki, 2012;Kumar et al, 2012;Oliveira et al, 2012;Padmavath et al, 2013;Ragab et al, 2013;Eldomiaty et al, 2014;Nagalaxmi et al, 2014;Hernández et al, 2015;Lima et al, 2016;Maloth et al, 2016;Moshfeghi et al, 2016;Saxena, et al, 2016;Kumar et al, 2017;Jain, Poojitha & Bhatia, 2018;Loganadan et al, 2019). É considerada imutável, pois pode ser observada que há reparação da forma original dos lábios após uma lesão (Prabhu, Dinkar, Prabhu & Rao, 2012).…”

“…A região geográfica dos estudos variou, sendo 3 estudos no Brasil (Barros, 2006;Oliveira, Rabello & Fernandes, 2012;Lima, Costa, da Silva, do Nascimento, de Moraes & de Souza Lucena, 2016) e os demais foram realizados no exterior, como, por exemplo: 10 estudos na Índia (Augustine, Barpande & Tupkari, 2008;Sharma, Saxena & Rathod, 2009;Kumar, Vezhavendhan & Vendhan, 2012;Padmavath, Makkad, Rajan & Kolli, 2013;Nagalaxmi, Ugrappa, Naga Jyothi, Maloth & Kodangal, 2014;Maloth et al, 2016;Alzapur et al, 2017;Chaudhari et al, 2017;Kumar, 2017;Jain et al, 2018), 1 no Egito (Ragab et al, 2013), 1 na Colômbia (Hernández, Pabón & Paredes, 2015), 1 em Portugal (Costa & Caldas, 2012), 1 no Reino Unido (Saxena, Kumar & Sharma, 2016), 1 no Irã (Moshfeghi, Beglou, Mortazavi & Bahrololumi, 2016), 2 na Arábia Saudita (El Domiaty, Al-Gaidi, Elayat, Safwat & Gathe, 2010;Eldomiaty, Anwar & Algaidi, 2014), 1 no Nepal (Karki, 2012), e 1 na Indonésia (Loganadan, Dardjan, Murniati, Oscandar, Melinda & Zakiawat, 2019).…”

Dental Radiographic/Digital Radiography Technology along with Biological Agents in Human Identification

“…Another adjuvant tool employing lip prints in forensic investigations is lip outline patterns. Maloth et al have shown that lip outline patterns have the potential to be used for human identification since they are individually unique [ 146 ].…”

Application of Nanotechnology for Development of Latent Lip Prints: A Review

“…Since ancient times, the presence of a person at the crime scene used to be predicted by the fingerprints found at the crime scene. [1][2][3][4][5][6][7] Collection of fingerprints became the prerequisite of any forensic investigation. The fingerprint powder will fix to the residues left by the finger and give rise to the distinctive patterns that help to identify an individual.…”
