Özet
Amaç: Bu çalışmanın amacı farklı dik yön gelişim modellerine sahip iskeletsel Sınıf I bireylerde yüzün yumuşak doku kalınlıklarını değerlendirmektir. Gereç ve Yöntem: Çalışmamız 14-18 yaşlar arasındaki iskeletsel Sınıf I bireylere ait ortodontik tedavi öncesinde alınmış olan 210 sefalometrik film (105 kadın, 105 erkek) üzerinde yürütüldü. SN-GoGn açısına göre (normal 26 < SN-GoGn <38, hipo SN-GoGn < 27 ve hiper SN-GoGn >37) üç grup oluşturuldu. Sefalometrik filmler üzerinde dijital yazılım programı kullanılarak sert dokularda 6 adet açısal ölçüm ve 10 adet yumuşak doku kalınlık ölçümü yapıldı. Gruplar ANOVA, Spearmean's Korelasyon ve Bağımsız t-Testi kullanılarak istatiksel olarak değerlendirildi. Bulgular: Cinsiyet ayrımı yapılmadan gruplar karşılaştırıldığında, burun (Ac-Pn), üst dudak (Pr-Lsp), alt dudak (Id-Lip) ve çene ucu yumuşak doku kalınlıklarında (Pog-Pog?, Gn-Gn?, Me-Me?) istatistiksel olarak anlamlı farklar bulundu (p<0.05). Gruplar arası karşılaştırılmada, kadınlarda Ac-Pn, Pr-Lsp, Id-Lip, Pog-Pog?, Me-Me? parametrelerinde; erkeklerde ise, Ac-Pn, Pr-Lsp, Id-Lip, Me-Me? parametrelerinde istatistiksel olarak anlamlı fark bulundu (p<0.05). Kadın-erkek karşılaştırılmalarında Ac-Pn, A noktası düzeyinde üst dudak kalınlığı (A-A?), Pr-Lsp, Id-lip kalınlıkları kadınlarda erkeklere kıyasla daha düşük bulundu. Kadınlarda ve erkeklerde Sn-GoGn parametresi ile burun, dudaklar ve çene ucu kalınlıkları arasında negatif ilişki bulundu. Ayrıca, üst dudak kalınlığı ile çenelerin sagittal konumları ilişkili bulunurken, kadınlarda B noktası düzeyindeki alt dudak kalınlığı ile üst kesici eğimi arasında önemli bir ilişki saptandı. Erkeklerde alt dudak kalınlığı, çenelerin konumu ve kesicilerin eğimi arasında bir ilişki saptanmadı. Sonuç: İskeletsel Sınıf I bireylerde yüzün vertikal büyüme modelinin, yumuşak doku kalınlıklarında etkisi olduğu belirlendi. Genel olarak, vertikal gelişimi fazla olan bireylerde yumuşak doku kalınlıklarının düşük olduğu belirlendi.

Aim: The aim of this study was to evaluate the soft tissue thickness of the face in skeletal Class I individuals with different vertical growth patterns. Material and Methods: This study was conducted on pre-treatment cephalometric radiographs (105 female,105 male) of 210 skeletal Class I individuals aged between 14 and 18 years. The individuals were divided into 3 groups according to SN-GoGn (normodivergent; 26?37?). 6 angular hard tissue and 10 soft tissue measurements were performed using dijital imaging software. The groups were statistically compared using ANOVA, Spearman's Correlation and Independent Samples t-Test. Results: When the groups were compared without gender discrimination, there was a statistically significiant difference in nose (Ac-Pn), upper lip (Pr-Lsp), lower lip (Id-Lip) and soft tissue chin (Pog-Pog?, Gn-Gn?, Me-Me?) thickness (p<0.05). The difference in Ac-Pn, Pr-Lsp, Id-Lip, Pog-Pog?, Me-Me? parameters were statistically significant between study groups in female subjects and Ac-Pn, Pr-Lsp, Id-Lip, Me-Me? parameters in male subjects. When the male and female subjects were compared, Ac-Pn, the upper lip thickness at the A point level (A-A?), Pr-Lsp and Id-Lip parameters were lower in female subjects than male subjects. There was a negative correlation between SN-GoGn and nose, lips and chin thickness in both male and female individuals. In addition, while the upper lip thickness was correlated with sagittal position of jaws, a significiant relationship was found in female between the lower lip thickness at the B point level and the upper inclination of the incisors. In men, no correlation was found between the thickness of lower lip, the position of the jaws and the inclination of the incisors. Conclusion: In skeletal Class I individuals, the vertical growth pattern effects the soft tissue thickness of the face. The soft tissues of the face decreased in individuals with increased vertical skeletal growth. Keywords: Soft tissue thickness, Skeletal Class I malocclusion, Vertical growth pattern
