Abstract

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

Abstract

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.
