3. Introduction
 Lip prints, also known as cheiloscopy, is the
study of lip impressions left on surfaces
such as glass, paper, or other objects.
 The uniqueness and permanence of lip
prints make them a valuable tool in forensic
investigations.
 In this presentation, we will explore the
classification of lip prints and their
significance in forensic science.

4. Lip print Types
• Lip prints can be classified into different
types based on their characteristics.
• There are generally four main types of lip
prints:
• Vertical Groove Pattern
• Radial Groove Pattern
• Dotted Pattern
• Branched Pattern

5. Vertical Groove Pattern
 Vertical groove patterns consist of
vertical lines or furrows.
 They are further classified into types A,
B, and C based on the arrangement and
distribution of lines.
 Type A: Straight lines that run vertically
from the upper lip to the lower lip.
 Type B: Oblique lines that intersect with
the vertical lines.
 Type C: Vertical lines with branching or
secondary lines.

6. Radial Groove Pattern
 Radial groove patterns have lines that
radiate from a central point.
 They are classified into types I, II, and III
based on the arrangement and distribution
of lines.
 Type I: Lines radiating from a single point
on the upper or lower lip.
 Type II: Multiple lines radiating from
more than one point on the upper or lower
lip.
 Type III: Intersecting lines forming a
crisscross pattern.

7. Dotted Pattern
 Dotted patterns consist of small dots or
spots on the lip surface.
 These dots can be irregularly distributed or
form distinct patterns.
 The arrangement and distribution of the
dots help in the classification of this lip
print type.

8. Branched Pattern
 Branched patterns involve the presence of
branched lines on the lip surface.
 The branching can occur in different
directions and angles.
 The classification of branched patterns is
based on the complexity and distribution of
the branches.

9. Significance in Forensic Science
 Lip prints are considered a valuable tool in forensic science for individual
identification.
 The uniqueness of lip prints allows for the establishment of a person's
identity.
 Lip prints can be left at crime scenes, on objects, or as evidence in cases
like assault or homicide.
 By classifying and comparing lip prints, forensic experts can link them to
potential suspects or victims.

10. Conclusion
 Lip print classification plays a vital role in forensic science and
the identification of individuals.
 The unique patterns and characteristics of lip prints make them
valuable evidence in criminal investigations.
 Ongoing research and advancements in lip print analysis
techniques continue to enhance their accuracy and reliability.
