Perbedaan Pola Sidik Lidah Antara Etnik Batak dan Tionghoa Berdasarkan Klasifikasi Stefanescu di Fakultas Kedokteran Gigi Universitas Sumatera Utara

Abstract

Tongue is an important organ in life and has varying shapes, fissures, textures and lingual apex. This variation is caused by genetic factors that differ in each person's gender and ethnicity. Tongue prints are a unique biometric tool and are well protected from the external environment because they are in the oral cavity. Objective: to determine and analyze differences in tongue print patterns between Batak and Chinese ethnic groups based on shape, fissures, texture, lingual apex in ethnic Batak and Chinese students at the Faculty of Dentistry, University of North Sumatra. Method: This is a type of descriptive-analytic research with a cross sectional design, the sample consists of 30 ethnic Batak people (15 women and 15 men) and 30 ethnic Chinese people (15 women and 15 men) at the Faculty of Dentistry, University of North Sumatra . The tongue is molded using alginate (irreversible hydrocolloid) material then filled with a type IV cast, and a digital photo is taken using a professional camera. Tongue print pattern data was analyzed based on Stefanescu et al's classification, described in percentage values and tabulation followed by the chi-square statistical test (X2). Results: The differences in patterns in this study varied. The most common tongue print patterns in Batak ethnic women are based on shape: V-shape (53.3%), Fissure: Visible (80.0%), Texture: Physiological (100%), and Lingual apex: Sharp (80.0%) . The most common tongue print patterns in Batak ethnic males are based on shape: U-shape (46.7%), Fissure: Visible (80.0%), Texture: Physiological (100%), and Lingual apex: Sharp (73.3 %). The most common tongue print patterns in ethnic Chinese women are based on shape: Ovoid (60.0%), Fissure: Visible (86.7%), Texture: Physiological (100%), and Lingual apex: Sharp (73.3%). The most common tongue print patterns in Chinese ethnic males are based on shape: Ovoid (53.3%), Fissure: Visible (93.3%), Texture: Physiological (100%), and Lingual apex: Sharp (80.0%) . Conclusion: There is no significant difference in tongue print patterns between the two sexes in Batak and Chinese ethnic groups and there is a significant difference in tongue print patterns between Batak and Chinese ethnic groups based on aspects of tongue shape (p-value = 0.022 < 0.050)
