はじめに:
笑顔時の上顎歯の過剰な露出は、顔の審美性や魅力に悪影響を及ぼす可能性があります。今回の研究では、年齢、魅力、性別、共感などの人間の特徴や資質の知覚に対して、歯肉の露出量の違いが与える影響を、顔全体の文脈で評価することを目的とした。
INTRODUCTION: Excessive exposure of maxillary teeth when smiling can have a negative effect on the aesthetics and attractiveness of the face. The presented study was aimed to evaluate the effect of different amounts of gingival exposure on the perception of such human characteristics and qualities as age, attractiveness, gender specificity, and felt sympathy in the context of the whole face.
材料と方法:
本研究の評価者として42名の被験者(歯科医学生女性21名、男性21名)を募集しました。平均的な顔立ちの被験者2名(女性1名、男性1名)を撮影した。画像を処理して,歯肉露出の異なる8つのクローンを作成した(シフトA-H;A=完全な過剰露出,H=歯冠面の見えない状態).パネリストは,魅力度,性別の特異性,年齢,共感度などの特性を評価した.
MATERIALS AND METHODS: Forty-two participants (21 female and 21 male students of Dental Medicine) were recruited as evaluators for the study. Two average-looking subjects (one female, one male) were photographed. The images were processed to create a series of eight clones with different gingival exposure (shift A-H; A = full over-exposure, H = invisibility of the crown surfaces of the teeth). The panellists evaluated characteristics as attractiveness, gender specificity, age, and felt sympathy.
結果:
42名の参加者(女性21名、男性21名)が研究に参加した。シフトHは、共感度と魅力度が最も低く、推定年齢も最も高い結果となった。魅力度が最も高かったのは、CとDのシフトであった。また、同性は魅力度が低く、異性は魅力度が高いという性別の二型が見られた。
RESULTS: 42 participants joined the study (21 female, 21 male). Shift H was assessed as worst for sympathy and attractiveness, and resulted in the highest estimated age. Best attractiveness was observed for shifts C and D. Gender dimorphism was noticed, with own gender being rated as less attractive and opposite gender as more attractive.
結論:
女性評価者と男性評価者では、歯肉と上顎切歯の過度の露出に対する評価が異なる。笑顔時の上顎歯肉と歯の過度の露出は魅力的でないと認識され、観察者の共感を得られない。
CONCLUSIONS: Female and male evaluators assess excessive gingival and maxillary incisor display differently for female and male probands. Excessive over- or underexposure of the maxillary gingiva and teeth when smiling is perceived as unattractive and results in less observer sympathy.
