Özet:

 Objective: To investigate dimensions and morphological characteristics of Sella Turcica ST in patients with impacted maxillary canines IMC, compared to a control group of patients with normally erupted canines, using CBCT images. A secondary aim was to investigate the relationship between the impaction severity and ST parameters. Methods: This retrospective study analyzed CBCT images from 100 patients. The study group included 55 subjects with IMC n38 unilateral, U-IMC; n17 bilateral, B-IMC and the control group included 45 subjects exhibiting normally erupted canines. ST parameters included linear dimensions length, depth, diameter, morphological categorization and bridging types. IMC parameters were canines three-dimensional positional angles according to Frankfort Horizontal Plane FHP and midsagittal plane MP. Statistical analyses were conducted using two-sample t-test, Man-Whitney U, and One-Way ANOVA tests. Statistical significance was set at 5. Results: U-IMC-R and B-IMC exhibited significantly higher FHP-RC-Frontal p0.001 and MP-RC p0.002 angles, but a lower FHP-RC-Lateral angle p0.001 compared to U-IMC-L and control groups. Moreover, U-IMC-L and B-IMC groups exhibited significantly higher FHP-LC-Frontal p0.001 and MP-LC p0.001 angles, but a lower FHP-LC-Lateral angle p0.003 compared to U-IMC-R and control groups. There was a significant inverse relationship of 25.5 between ST length and FHP-LC-Lateral angle p0.011. Conclusion: IMC was linked with increased FHP-C-Frontal and MP-C angles, but with a decreased FHP-C-Lateral angles. A significant 25.5 inverse relationship between ST length and FHP-LC-Lateral angle was observed. Besides, IMC occurrence and its three-dimensional position did not exhibit correlation with STs dimensions or morphology.

 AMAÇ: DVT görüntüleri kullanılarak, gömülü maksiler kanin dişi IMC sahip hastalarda Sella Turcicanın ST boyutları ve morfolojisi, normal şekilde sürmüş kanin dişlerine sahip kontrol grubu hastalarla karşılaştırarak araştırmak amaçlandı. İkincil amaç, gömüklük şiddeti ile Sella Turcica parametreleri arasındaki ilişkiyi incelemektir. GEREÇ VE YÖNTEM: Bu retrospektif çalışmada 100 hastadan alınmış DVT görüntüleri analiz edildi. Çalışma grubuna 55 IMCye sahip hasta n38 tek taraflı, U-IMC; n17 çift taraflı, B-IMC ve normal şekilde sürmüş kanin dişlerine sahip 45 kontrol hastası dahil edildi. STnın parametreleri; doğrusal boyutları uzunluğu, derinliği, çapı, morfolojik sınıflandırma ve köprüleşmesi tiplerinden oluşuyordu. IMC parametreleri, kaninin Frankfort Horizontal düzlemi FHP ve midsagittal düzleme MP göre üç boyutlu pozisyonel açılarından oluşmaktaydı. İstatistiksel analizler, iki-örneklem t-testi, MannWhitney U ve Tek-Yönlü Varyans Analizi ANOVA testleri kullanılarak gerçekleştirildi. İstatistiksel anlamlılık düzeyi 5 olarak belirlendi. BULGULAR: U-IMC-R ve B-IMC grupların, U-IMC-L ve kontrol gruplarına kıyasla, FHP-RC-Frontal p0.001 ve MP-RC p0.002 açılarında istatistiksel olarak anlamlı derecede daha yüksek, ancak FHP-RC-Lateral açısında p0.001 daha düşük olduğu bulundu. U-IMC-L ve B-IMC grupların, U-IMC-R ve kontrol gruplarına kıyasla, FHP-LC-Frontal p0.001 ve MP-LC p0.001 açılarında istatistiksel olarak anlamlı derecede daha yüksek, ancak FHP-LC-Lateral açısında p0.003 daha düşük olduğu bulundu. STnın uzunluğu ile FHP-LC-Lateral açısı arasında 25.5 istatistiksel olarak anlamlı ters ilişki bulundu p0.011. SONUÇ: IMC, etkilenen gömme tarafında artmış FHP-C-Frontal ve MP-C açıları ile ilişkilendirilirken, azalmış FHP-C-Lateral açıları ile ilişkilidir. STnın uzunluğu ile FHP-LC-Lateral açısı arasında 25.5 ters ilişki vardır. Bunun dışında, IMCnin varlığı ve üç boyutlu pozisyonu, STnin boyutları veya morfolojisindeki değişikliklerle korelasyon göstermemektedir.
