Evaluation of morphological pattern of lip print in a Turkish subpopulation

Öz

OBJECTIVE: The aim of this study was to determine morphologic pattern of lip print and to evaluate the differences between the sexes. METHODS: 60 subjects consisting of 30 females and 30 males participated in the study and lip print of each subject was obtained through using a dark-colored lipstick and cellophane tape. Lip prints were evaluated using a magnifying lens and categorized according to the Suzuki and Tsuchihashi classification of lip prints. Pearson chi-square test was applied to compare the differences between the sexes. RESULTS: Type I’ pattern was found out to be the most common type in upper right lip whereas type II pattern revealed to be the most frequently encountered one in upper left lip. Furthermore, type II pattern was found to be the most common in lower left lip, and type I’, type II and type III pattern appeared to be the most prevalent pattern in lower right lip among males. Type I’ pattern was found to be the most common in upper right lip while type I’ pattern appeared to be the most common in upper left lip. In addition, type II pattern revealed to be the most common in lower left lip, and type II pattern was found to be the most frequently encountered one in lower right lip among females. The difference in morphologic pattern of lip print is not statistically significant between the sexes p>0.05 . CONCLUSION: Type I’ pattern was found out to be the most common pattern in females while Type II pattern was encountered most in males. Distribution of lip print morphologic pattern was not affected by the sex.

Bir grup Türk popülasyonunda dudak izinin morfolojik yapısının incelenmesi

Öz

AMAÇ: Bu çalışmanın amacı Türk toplumunda dudak izinin morfolojik yapısını belirlemek ve cinsiyetler arasındaki farklılıkları değerlendirmektir. YÖNTEM: Çalışma 30 erkek 30 bayan olmak üzere 60 bireyden oluşmaktadır. Her bir bireyin dudak izleri koyu renkli dudak boyası ve selefon bant aracılığıyla temin edilmiştir. Dudak izleri büyüteç ile değerlendirilmiş ve Suzuki ve Tsuchihashi sınıflamasına göre sınıflandırılmıştır. Cinsiyetler arasındaki farklılığı tespit etmek amacıyla Pearson ki-kare testi kullanılmıştır. BULGULAR: Erkeklerde üst dudak sağ kısmında en sık gözlenen dudak izi tipinin Tip I’, üst dudak sol kısımda Tip II, alt dudak sol kısımda Tip II, alt dudak sağ kısımda ise Tip I’, Tip II ve Tip III olduğu bulunmuştur. Kadın bireylerde üst dudak sağ kısmında en sık gözlenen dudak izi tipinin Tip I’, üst dudak sol kısımda Tip I’, alt dudak sol kısımda Tip II, alt dudak sağ kısımda ise Tip II olduğu bulunmuştur. Dudak izinin morfolojik yapısı cinsiyetler arasında istatistiksel olarak farklılık göstermemiştir p>0,05 . SONUÇ: Kadınlarda en çok Tip I’, erkeklerde ise en çok Tip II dudak izi morfolojik yapısına rastlanmıştır. Dudak izinin morfolojik yapısı cinsiyetler arasında farklılık göstermemiştir.
