Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 1
Abstract
Lip print becomes one of physical evidence that can be relied upon to know the offender if found at the crime scene on glass cups, paper napkins or cigarette butts or other. The longer the time before manipulation of lip prints is the more unsuitable for emulation it become due to the ambient conditions. In this research the duration during which the lip prints is reliable as physical evidence on different surfaces (glass & paper) and in different circumstances was studied. Other aims of this work also is to find out the percentage of different types of lip print in people of Saudi Arabia and whether there are significant differences between males and females in different lines. This research was done on 50 Saudi volunteers; 18 males and 32 females whose ages ranged between 19 and 55 years. Lip print was classified according to Tsuchihashi’s classification. The duration of reliability of lip print on different surfaces and in different circumstances were observed until 12 weeks to. It was found that type I’ was the predominant line in the examined lip prints (44%) to be followed by type I (30.4%), then type II (10.2%), type V (8.8%), type III (4.6%), and type IV (2%). There were no significant differences for each type of lines between males and females. It was found also that lip prints on paper are more fixed than those on glass. The duration of reliability of lip print on paper may be up to 12 weeks even if exposed to ambient conditions, but duration of reliability of lip print on glass may be up to 9th week if kept in closed container in temperature adjusted around 25 oC, but if exposed to ambient conditions it may be up to 6th week.
