As previous authors claimed, these can be used for personal identification in forensic cases because they are unique, permanent, classifiable.

(Klein’s zone) was divided into 10 quadrants (five each upper lower lips) study pattern area thoroughly. sample-wise quadrant-wise frequency all statistically calculated. Sexual dimorphism also assessed statistically. Results method emphasizes consistency patterns, which Basic Combination Patterns. Detailed examination revealed that tend 7 types Patterns 43 despite similar appearance. further categorized various subtypes direction orientation wrinkle lines constituting original pattern. Most widely distributed analysed showed significant dependence sex subject. Conclusions examined useful as existing marks recovered at crime scene.
