Abstract

Human identification is essential needed to investigate criminals, mass disaster victim and certificates of death as well. In a certain case, however identification using primary data such as fingerprints, teeth, and DNA cannot be conducted because of the human body decomposition and evidence lost. So the secondary data is needed to make an easier identification. Lip print pattern provides secondary data that is unique, and easy to collect. Here we focused on determining the predominant lip print pattern to differentiate gender. The study is made of 138 people (68 males and 70 females), aged from 10 to 70 years, from Siberut, Mentawai. A 5x2 cm width cellophane tape was cut and stuck on both the lips together and pressed with even pressure for 3 seconds. Later, the tape was lifted from the lips carefully and adhere in a piece of white paper as a permanent record. The print was examined 3 times using a magnifying lens then classified using Suzuki lip pattern classification ..Percentage calculation method was used to identify the predominant lip pattern. The present study concludes that every individual has unique lip print and Type IV appears to be the most predominant pattern in males, type 1 appears to be the most predominant pattern.
