Morphological patterns of lip prints in an Iranian population

et al. 2016

BackgroundLip prints are verified to be unique to an individual and stable over time; hence they have potential for human identification purposes. The aim of this study was to assess the individuality and variability of lip prints in an Iranian population for the first time. We also sought to assess the possibility of sex determination via lip printing.Material and MethodsLip prints of 96 individuals including 22 males and 74 females were recorded on a plain white paper using a dark-colored lipstick and 50 mm of Scotch tape. Each lip print was divided into six sextants and studied independently by two observers using a magnifying lens to examine the lip grooves. The Suzuki and Tsuchihashi’s classification was used to define the lip patterns and the data were statistically analyzed.ResultsIn the present study, no identically similar lip prints were observed. Type V was the most predominant pattern recorded in the study sample (33.16%), followed by type I (24.13%), type II (18.75%), type IV (11.63%), type I’ (9.72%) and type III (2.60%). In addition, no statistically significant difference was observed in the lip print patterns of males and females.ConclusionsIt can be concluded that lip prints are unique and their analysis may enable human identification. Key words:Forensic anthropology, forensic dentistry, forensic medicine, iran, lip.

RESUMEN: Aunque existen métodos de identificación humana más o menos frecuentes en uso, todos ellos se soportan en la comparación inequívoca, científica y fiable, de una información conocida con la obtenida de los restos o de las huellas a procesar. Desde una perspectiva odontológica forense, los surcos labiales, las rugas palatinas y sus negativos o huellas, han sido reconocidos como patrones morfológicos que permitirían identificar a una persona en circunstancias específicas. Estos elementos han sido estudiados tanto comparativa como independientemente buscando detectar las características individuales y poblacionales que permitan reforzarlos como herramientas significativas: se ha informado que tanto la Queiloscopía (el estudio de las huellas labiales) como la Rugoscopía (el estudio de las rugas palatinas) definen rasgos únicos para cada individuo, por lo tanto utilizables razonablemente para una identificación forense. Dado que los reportes de casos forenses permiten identificar cambios en las conductas criminales, en los patrones morfológicos característicos o en la manera de presentar la evidencia pericial, se presenta una revisión de reportes de casos con utilización de evidencia rugoscópica y queiloscópica, junto con discutir sus proyecciones hacia la comunidad científica forense.PALABRAS CLAVE: odontología forense, rugoscopía, queiloscopía, reportes de casos. INTRODUCCIÓNLa identificación humana es uno de los campos más abordados e investigados por los científicos forenses y, sea para establecer la identidad de restos humanos en diferentes grados de vulneración o la de sospechosos de haber cometido un crimen, el proceso requiere de una combinación de recursos correctamente aplicados, cuyos resultados deben ser apropiadamente interpretados y presentados al proceso judicial. Aunque existen métodos más o menos frecuentes en su uso para este procedimiento, todos ellos se soportan en la comparación inequívoca, científica y fiable, de una información conocida con la obtenida de los restos o de las huellas a procesar. La cavidad oral ha probado ser fuente de datos y posibilidades con la que este proceso podría realizarse en una cohorte definida. Entre ellos, los surcos labiales, las rugas palatinas y sus negativos o huellas, han sido reconocidos como patrones morfológicos que permitirían identificar a una persona en circunstancias específicas. Estos elementos han sido estudiados tanto comparativa como independientemente buscando detectar las características individuales y poblacionales que permitan reforzarlos como herramientas significativas: se ha informado que tanto la Queiloscopía (el estudio de las huellas labiales) como la Rugoscopía (el estudio de las rugas palatinas) definen rasgos úni-cos para cada individuo, por lo tanto utilizables razonablemente para una identificación forense (Caldas et al., 2007).Dado que los reportes de casos en ciencias forenses permiten identificar cambios en las conductas criminales, en los patrones morfológicos característicos o en la manera de presentar la evidencia pericia...

“…One approach is to perform lip print analysis, which has a unique wrinkle pattern and characteristics that can lead to the identification of an individual. This science is called cheiloscopy, a forensic investigation technique that deals with identification of people based on lips traces (Dineshshankar, Ganapathi, Kumar, Aravindhan, & Maheswaran, ). Forensic odontologists also assess dental records to investigate the identity of unknown person's identity.…”

Dentists should have the basic essential skills and knowledge about forensic odontology, to better collaborate with law enforcement and investigations. The objective of this survey was to assess the perceived and actual knowledge toward forensic odontology among dentists and to question their willingness to attend training courses on this specialty. A cross‐sectional survey based on a self‐administered questionnaire was conducted in various districts of Saudi Arabia. Four hundred dentists responded to a questionnaire that tested their actual knowledge of forensic odontology based on answering 15 statements using the alternatives correct, incorrect, do not know. The perceived knowledge was registered as strongly agree, agree, neutral, disagree, and strongly disagree, then assigned scores respectively from four to zero. A willingness to attend a training course in the future was recorded by (yes/no). Scores were summated then subjected to descriptive statistics and regression analyses. Responses were received from 360 study participants (89% response rate). The percentage of correct answers, that is, the actual knowledge, was 67.9 (standard deviation [SD] ± 18.4). About two thirds of the responders (n = 251, 69.7%) indicated a willingness to attend a forensic odontology course in the future. Differences in both actual and perceived knowledge were identified on the basis of gender, work experience, education level, attended a course in forensic odontology, and having previously provided a past bite‐mark examination. The perceived knowledge on forensic odontology among dentists was moderate to low. The gap between perceived and actual knowledge signifies low self‐confidence. Dentists with higher education levels and experience tend to have better knowledge.
