Identifikasi Pola Sidik Bibir pada Orang Tua dan Anak Kandung Suku Batak dalam Bidang Forensik

Abstract

Lip prints are one of identification in forensic odontology. One of the factors involved in lip print patterns is heredity. This is explained by Mendel's Law, where children inherit genes from their parents. Aim: to determine the distribution, frequency of dominant lip print patterns for each quadrant, dominance, and similarity of lip print patterns between fathers, mothers, male biological children and female biological children of the Batak tribe based on Suzuki and Tsuchihashi classification. Methods: observational analysis with cross-sectional design. Lip prints were taken using the lipstick method from 66 samples consisting of 22 fathers, 22 mothers, 11 male biological children and 11 female biological children. The lip prints were divided into four quadrants, the lip print patterns were observed based on Suzuki and Tsuchihashi classification. Results: the dominant lip print pattern of quadrant I in the subjects of father, mother, male biological children and female biological children was mostly Type II. The dominant lip print pattern of quadrant II in the subjects of fathers, mothers, male biological children is mostly Type II, while in the subjects of female biological children is mostly Type II, Type III and Type IV. The dominant lip print pattern of quadrant III in subjects of fathers and mothers is mostly Type III, while in subjects of male biological children and female biological children is mostly Type II. The dominant lip print pattern of quadrant IV in the subjects of fathers, mothers, male biological children and female biological children is mostly Type II. The dominant lip print pattern in the subjects of fathers, mothers, male biological children and female biological children is mostly Type II. There is a significant similarity in the lip print patterns of fathers and mothers with male biological children in quadrant IV, while the other quadrants do not show statistically significant similarities. There is no significant similarity in lip print patterns between fathers and mothers with female biological children. Conclusion: there are similarities in lip print patterns between parents and their children, but they are not absolute and still have different variations.
