Abstract

Cheiloscopy is one of the emerging techniques to study lip prints discovered in forensic science that can aid in crime investigation. It is important to establish this new aiding tool as criminals nowadays have become smarter at hiding their traces. Since lip print pattern is unique to each individual, this technique may help personal identification, particularly when identifying suspects at the crime scene. However, studies regarding lip print analysis are quite new and less reported in Malaysia. Objective: Therefore, this study aims to evaluate the uniqueness of the lip print patterns among Biomedical Science students and staff according to Suzuki and Tsuchihashi’s classification. Methodology: This study comprises of 76 subjects (16 males and 60 females) of Biomedical Science students and staff from the Department of Biomedical Sciences, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia (UPM). The lip impression was collected by applying a thin layer of lipstick to their lips. It was then lifted using a strip of 45 mm cellophane tape and pasted on plain A4 paper. The lip print pattern was visualised using a magnifying glass and classified accordingly. The results were statistically analysed using Fisher’s exact test through SPSS software. Results and Discussion: Based on the results obtained, type I was the dominant lip print pattern found in different variables tested in the present study, such as gender, ethnicity, blood group and state region. Type I lip print patterns were found in 43.8% and 33.3% among males and females, respectively. It was also dominantly found among the Malay (37.7%), Indian (33.3%), and Chinese (27.3%). Type I lip print pattern was also found to be dominant among subjects with blood group B+ (28.6%), AB+ (42.9%), O+ (42.3%) and O- (50.0%). For subjects with blood group A+, type I, type I’ and type III were equally found in 27.3% of them. Besides, type I was also predominantly found among subjects from the Northern (42.9%), Central (31.0%) and Southern (43.8%) regions of Malaysia. For subjects from the East Coast region, type I and type I’ were equally observed in 27.3% of them. However, the percentage of the dominant lip print pattern found in the present study was not significant (p>0.05) compared to the other variables (gender, ethnicity, ABO blood group and state region). Conclusion: The present study demonstrates that distinct types of lip print patterns were identified among individuals and suggests that cheiloscopy potentially be used as one of the investigating tools in forensic science. Hence, further study using a larger sample size is highly recommended to establish the potential of this technique for personal identification in crime investigation in Malaysia.
