Abstract
One of the areas of human
identification is Cheiloscopy, the name given to the study of the lips, their
characteristics (such as thickness, position of the grooves and grooves) and
the record of the impressions left by them. There are variations in the layout
of the lines and fissures of the lips, which are unique to each individual,
permanent and unchanging. The lip print rarely changes, enduring minor traumas
such as inflammation or sores. In criminal investigations, lip prints, visible
through the presence of lipstick, can be found on glasses, napkins, clothes,
cigarettes, indicating a relationship between the subject and the scene of the crime.
Latent impressions may be revealed employing specific chemicals such as powder
of silver and aluminum nitrate. Although it is not a very common method,
Cheiloscopy may become very useful in forensics due to the extensive amount of
valuable information that it brings. The objective of this study was to review
the literature on the use of Cheiloscopy in human identification, using
traditional and digital methods. It was found that the literature is still in
need of studies in this area. The advent of new digital technologies can
facilitate the implementation of technical expertise, generating speed and
objectivity. New research studies are necessary, especially in the development
of digital methods. The application of Cheiloscopy can greatlyhelp with Law, in
the identification of living suspects and dead individuals. In the end the
benefit will fall to society as a whole. Article published in: RGO - Rev Gaúcha Odontol., Porto Alegre, v.61, n.1, p. 113-120, jan./mar., 2013.
