There are majorly five classifications of Cheiloscopy for lip prints. These are:

  1. Clauco Martin Santos Classification
  2. Suzuki and Tsuchihashi lip print Classification
  3. Renaud lip Classification
  4. Afchar-Bayat Classification
  5. Kasprzak Classification

1. Clauco Martin Santos Classification

In 1960, Dr. Martins Santos proposed that lip characteristics could be used in personal identification and proposed a system for classifying lip prints. It is one of the simplest forms of classifying lip prints.

It has four major groups for simple pattern types and three groups for composite pattern types.

A. Santos Simple Classification Group for Lip prints

S.No.Simple Types
1.Straight line
2.Curved lines
3.Angled lines
4.Sine shaped lines

B. Santos Composite Classification for Lip Prints

S.No.Composite Types
1. Bifurcated
3. Irregular

2. Suzuki and Tsuchihashi Classification of Lip Prints

Two Japanese scientists, Yasuo Tsuchihashi and Kazuo Suzuki studied the patterns of grooves on human lips. They called these lip grooves “sulci laborium rubrorum”. They also conducted a study on twins and concluded that no two lips could be the same.

Type IClear cut vertical grooves that run across the entire lips
Type I’Similar to type I but that does not run across the entire lip
Type IIBranched groove (branched y pattern)
Type IIIIntersected grooves
Type IVReticular grooves
Type VUndetermined

3. Renaud Lip Print Classification

After studying 4000 lip prints, French scientist Renaud classified lip prints based on following types.

Type acomplete vertical
Type bincomplete vertical
Type ccomplete bifurcated
Type dincomplete bifurcated
Type ecomplete intersecting
Type fincomplete intersecting
Type greticular
Type hin the form of sword
Type jhorizontal
Type iother types

4. Afchar-Bayat Lip Print Classification

Afchar-Bayat, in 1979, classify lip prints based on groove patterns. And the following table state the Afchar-Bayat Lip print classification.

A1Vertical and straight grooves, covering the whole lip
A2Like the former, but not covering the whole lip
B1Straight branched grooves
B2Angulated branched grooves
CConverging grooves
DReticular pattern grooves
EOther grooves
