The Comparison of Smile Aesthetic of Males and Females Based on Buccal Corridor and Smile Arc

Abstract

In performing the orthodontic treatments, patients aim to improve their smile esthetical features which are influenced by the position, size, shape, and color of teeth. However, in recent decades, several aesthetical features that have been studied are buccal corridor, smile arc, incisor display, and gingival display. In this study, 32 subjects composed of 16 males and 16 females were photographed from the front-site by using a DSLR camera within smiling states. Smile arc and buccal corridor measurements were performed via Corel Draw 12 program. The extra broad and broad characteristics were found in male subjects which were 31.2% and 18.8% respectively, while the female subjects had a higher broad proportion of 43.7% and extra broad for 6.3%. The smile arc features in male subjects were found were straight smile (34.4%) and consonant smile (15.6%), in contrast, the percentage of the female students had a higher consonant smile (31.3%) than straight smile (18.8%). This study confirmed similar findings regarding the domination of the buccal corridor broad in the female population, whereas the extra broad is dominated by males. By contrast, the smile arc consonant is dominated by females, while the straight feature is dominated by males.

Lengkung Senyum dan Tampilan Gingiva Pada Senyum

“…di dalam penelitiannya melaporkan bahwa senyum yang paling banyak ditemukan pada pria adalah senyum lurus, sedangkan pada wanita banyak ditemukan senyum konsonan. 24 Penelitian oleh Pham dan Nguyen juga melaporkan bahwa lengkung senyum konsonan dianggap paling ideal dan paling bisa diterima secara estetika karena memberikan kesan penampilan bahagia, muda dan menarik, selanjutnya diikuti dengan lengkung senyum lurus dan lengkung senyum terbalik.22 Terdapat beberapa faktor yang dapat mempengaruhi lengkung senyum, yaitu perawatan orthodontik, pemendekkan insisivus sentral yang diakibatkan oleh atrisi, kebiasaan buruk seperti thumbsucking, pertumbuhan dentoalveolar posterior secara vertikal yang berlebihan.27 Kebiasaan thumbsucking sering menyebabkan gigi anterior rahang atas menjadi inklinasi ke arah labial, yang dapat menyebabkan lengkung senyum menjadi tampak lebih datar. Begitu juga dengan kebiasaan bruxism yang sering menyebabkan gigi anterior menjadi atrisi sehingga lengkung senyum akan tampak lebih datar.…”
