Correlation of lip prints and lip competence in children

Abstract

Introduction:Individual identification is a significant and difficult task in forensic search; it was based on logical values. A lip print is different in every living individual and does not change with time so it can be used as a tool in forensic investigations. The present work aimed to find out the correlation between lip prints and lip competence in the pediatric population of Davangere city.Materials and Methods:The study sample comprised of 103 children that is, 49 males and 54 females of aged between 4 and 14 years. The lip impression was made on a strip of cellophane tape on adhesive portion; it was then placed to a white bond paper. This serves as permanent record. In this study, we are followed the classification of patterns of the lines on the lips proposed by Tsuchihashi. For recording lip competence, we considered Ballard criteria.Results:Chi-square test was used to find out the degree of association between variables and to check out whether statistically significant differences exist.Conclusion:Lip prints are unique for every person and show differences according to the race and the ethnic origins of a person. The present study confirmed the distinctiveness of cheiloscopy but disproves any statistical correlation of lip print with lip competency.

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

“…The variety of lip print analysis methods has brought up an inconsistency in the related literature all over the world [ 136 ]. Among these various methods are photographing, direct prints onto paper, and generating lips 3D casts which finely display the lips groves using dental impression materials [ 137 ]. Comparison methods for lip prints (e.g., picture/lens magnification) have been facilitated using a computer [ 129 ].…”

Eficacia del método de Vahanwala en la determinación del sexo a través de la queiloscopia en impresiones escaneadas de un grupo de estudiantes peruanos

“…En 1967, Suzuki y Tsuchihashi efectuaron un estudio con la cual obtuvieron muestras de huellas labiales en varios sujetos para aplicar y aumentar los estudios de peritos, lo que perfeccionó dicha práctica. Investigaciones posteriores realizadas por Renaud, en los años 70, ratificaron la singularidad de cada huella labial 9 , 10 .…”
