Background: Cheiloscopy, often known as "human lip recognition," is one of the most intriguing new topics in forensic and criminal investigations.
Methodology: 120 healthy Egyptians (69 males and 51 females) were included, lip prints were taken using the lipstick tap method, and four lip dimensions were taken using caliber. Lip prints were classified into six types (Type I, I′, II, III, IV, and and Type V).
Results: sex was identified using lip print patterns and lip dimensions at an accuracy 84 %. For males alone, type II was the most predominant type followed by type I′ then type IV, III and type V respectively, for females, type I was the most predominant type followed by type I′.
Conclusion: Lip print patterns are a hopeful tool in sex determination among Egyptians put in the hand of a forensic investigator. Besides other tools, further studies are needed on larger samples and to compare with other populations using the same method to construct sex-identifying models using lip prints.
