Oküler Protezlerin İris Renginin Oluşturulmasında Boyama ve Dijital Görüntüleme Yöntemlerinin Karşılaştırılması

Amaç: Bu çalışmada oküler protezlerin iris renklendirilmesinde kullanılan dijital görüntüleme ve boyama yöntemlerinin başarısının karşılaştırılması amaçlanmıştır.Gereç ve Yöntem: Ege Üniversitesi Diş Hekimliği Fakültesi’ne çeşitli nedenlerle başvuran göz küresini kaybetmiş 36 olguya iris renklendirilmesinde klasik boyama yöntemi ve dijital görüntüleme yöntemi kullanılarak iki adet oküler protez yapıldı. Boyama ve dijital görüntüleme yöntemlerini karşılaştırmak için Adobe Photoshop bilgisayar yazılım programı kullanıldı.Bulgular: Tüm veriler tek yönlü varyans analizi, ikili karşılaştırmalar t-testiyle yapılmıştır. Sağlıklı göz irisi ile dijital görüntüleme yöntemi ile hazırlanan iris arasındaki renk farkı ile sağlıklı göz irisi ile boyama yöntemi ile hazırlanan iris arasındaki renk farkı t- testi ile istatistiksel olarak analiz edildiğinde fark anlamlı bulunmuştur (P<0.05). Sonuç: Dijital yöntemin ΔE değeri boyama yöntemine göre az olmasına rağmen, boyama yöntemi de kabul edilebilir sınırlar içindedir. Boyaların kat kat uygulanması irisin optik özelliklerini daha iyi taklit etmekte, daha doğal ve derin bir görünüm vermektedir.

Comparison of Painting and Digital Imaging Methods in the Fabrication of Iris Color of Ocular Prostheses

Aim: The aim of this study was to compare the success of digital imaging and painting methods used in iris staining of ocular prostheses.Materials and Methods: Two ocular prostheses of one with staining and the other with digital imaging techniques were fabricated for 36 patients who lost their eyeball and applied to Ege University Faculty of Dentistry for various reasons. Adobe Photoshop computer software program was used to compare painting and digital imaging methods.Results: Data were analyzed with one-way analysis of variance, multiple comparisons were made with t-test. The iris color difference between the healthy eye and the digital technique iris and the difference between healthy eye and painting technique iris was found statistically significant (P<0.05). Conclusion: Although the ∆E value of the digital method is less than the painting method, the painting method is within acceptable limits. The incremental application of the paints better mimics the optical properties of the iris, giving a more natural and deep appearance.
