Özet:

 Objectives: The perception of facial attractiveness plays a significant role in social interactions and self-esteem. This study aimed to investigate the influence of different maxillary incisor inclinations and lower anterior facial heights on the perception of beauty, as well as to identify the threshold at which these variables begin to affect facial attractiveness. Materials and Methods: A female patients smiling extraoral profile photograph with ideal skeletal relation and Class I dental relationship along with an ideal overjet, and overbite served as the base image. Digital alterations were made to create three different lower-anterior-facial-height variables: reduced, normal, and increased. Each variable was combined with seven different maxillary incisor inclinations. These modified images were then evaluated by three different groups: orthodontists OR, clinicians CL, and laypeople LP, using a Likert-type scale. Statistical analysis was conducted using SPSS version 25 IBM, New York, NY, with a significance level set to p0.05. Results: For normal, reduced, and increased lower-facial-height LP and CL preferred 5º retroclined maxillary incisor, while OR preferred normal inclinations 87º. All groups displayed greater criticality toward reduced lower-facial-height when scoring incisor inclination. The most significant difference p0.000 among the groups was observed in the reduced lower-facial-height alteration with 5º incisor inclination. Here, most of OR 60 and half of CL 50 rated it as average, whereas half of LP 50 as unattractive. Conclusion: OR favoured normal and slightly labial 5º crown-torque, while showing resistance towards lingual crown inclination across all variables of lower-facial-height. However, LP and CL exhibited more tolerance towards lingually inclined incisors, contributing to a more feminine appearance. These findings can assist clinicians in making informed decisions during treatment planning, leading to improved esthetical outcomes and patient satisfaction.

 Amaç: Yüz çekiciliğinin algılanması, sosyal etkileşimlerde ve özsaygıda önemli bir rol oynar. Bu çalışma, farklı maksiller kesici eğimlerinin ve alt ön yüz yüksekliklerinin güzellik algısı üzerindeki etkilerini araştırmayı amaçlamaktadır. Ayrıca, bu değişkenlerin yüz çekiciliğini etkilemeye başladığı eşikleri belirlemeyi hedeflemektedir. Gereç ve Yöntemler: İdeal iskelet ilişkisi ve Sınıf I dişsel ilişkisi ile birlikte ideal overjet ve overbitea sahip bir kadın hastanın gülümseme ağız-dışı profil fotoğrafı, temel görüntü olarak kullanılmıştır. Azaltılmış, normal ve artırılmış olmak üzere üç farklı alt-ön-yüz-yüksekliği değişkeni oluşturmak için dijital değişiklikler yapılmıştır. Her değişken, yedi farklı maksiller kesici eğim ile birleştirilmiştir. Bu değiştirilmiş görüntüler daha sonra üç farklı grup ortodontistler OR, klinisyenler CL ve bağımsız kişiler LP tarafından bir Likert tipi ölçek kullanılarak değerlendirilmiştir. İstatistiksel analiz, SPSS 25 IBM, New York, NY sürümü kullanılarak anlamlılık düzeyi p0.05 düzeyinde gerçekleştirilmiştir. Bulgular: Normal, azaltılmış ve artırılmış alt-yüz-yüksekliği için, LP ve CL grupları 5º retrokline maksiller kesici eğimini daha estetik olarak tercih ederken, OR grubu normal eğimleri 87º tercih etmiştir. Tüm gruplar, kesici eğimi değerlendirirken azaltılmış-alt-yüz-yüksekliğine karşı daha büyük bir eleştirellik sergilemiştir. Gruplar arasındaki en önemli fark p0.000, 5º kesici eğimli azaltılmış-alt-yüz-yüksekliği değişikliğinde gözlenmiştir. Burada, ORnin çoğu 60 ve CLnin yarısı 50 bunu ortalama olarak değerlendirmiştir, LPnin yarısı 50 ise çekici bulmamıştır. Sonuç: Ortodontistler normal ve hafif labial 5º taç torkunu tercih ederken, alt-yüz-yüksekliği değişkenlerinin tümünde lingual kron eğimine karşı direnç gösterdi. Bununla birlikte, bağımsız kişiler ve klinisyenler, feminen bir görünüm sağlayan lingual eğimli kesicilere karşı daha fazla beğeni sergilemişlerdir Bu bulgular, klinik uzmanlara daha bilinçli kararlar ile tedavi planlaması yaparak daha estetik sonuçlara ve artmış hasta memnuniyetine ulaşmalarına yardımcı olacaktır.
