A Study of Morphological Patterns of Lip Prints among The Yorubas in Okitipupa, South-western Nigeria
Keywords:
Cheiloscopy, Criminology, Forensic AnthropologyAbstract
Introduction: In civil and criminal cases, human identification is a very important process. Analysis of the lip prints left at a scene of crime, and their comparison with those of the suspected person may be useful for identification.
Aim: The purpose of this study was to assess the lip print patterns of the Yorubas of Nigeria, using Okitipupa as a case study.
Materials and Methods: This cross-sectional study adopted the random sampling technique and consisted of 104 individuals (53 males and 51 females), aged between 10 and 50 years. Lipstick was applied uniformly on the lips of each subject, and allowed to dry for about two minutes, after which an impression was made on a plain white paper. The impression was subsequently visualized with a magnifying lens and the patterns of lip prints were noted and recorded. 832 lip prints were recorded and type II was found to be the dominant pattern.
Results: There was no significant association between gender and lip print patterns. This study confirms that lip prints are unique for every individual.
Conclusion: No two lip prints are the same. The sex of an individual cannot be determined from lip prints.
