Background: The purpose of this in-vitro study was to evaluate the repeatability and interdevice reliability of two identical spectrophotometers with different software.
Methods: Twenty-six shade tabs of a shade guide (Vita 3D-Master, Vita Zahnfabrik) were measured with two identical spectrophotometers (Vita EasyShade V) with different software (v509i: Device A; v505p: Device B), and CIELAB values were recorded (n=260). The color difference (∆E00) values between measurements of spectrophotometers were calculated. For repeatability, the 3M2 shade tab of the same shade guide was measured 50 times with each spectrophotometer. The matching accuracy rate of the devices with shade guide was calculated. Interdevice reliability and differences between devices were calculated using intraclass correlation coefficient (ICC), Cronbach's alpha, and Paired T-test (α=0.05).
Results: Interdevice reliability was found to be high for L*, a*, and b* parameters (ICC>0.99). The ∆E00 values of the shade tabs range from 0.21 to 1.78, which were lower than the acceptability threshold (∆E00<1.8). The mean L* value of Device A was significantly higher than that of Device B (P<0.001), while the mean a* and b* values were significantly lower (P<0.001). The repeatability is excellent for a* and b* parameters (SD<0.1), however, slightly lower for the L* (0.15

Amaç: Bu in-vitro çalışmanın amacı, farklı yazılımlara sahip özdeş iki spektrofotometrenin tekrarlanabilirliğini ve cihazlar arası güvenilirliğini değerlendirmektir.
Gereç ve Yöntemler: Bir renk skalasına (Vita 3D-Master, Vita Zahnfabrik) ait 26 adet renk tabı, farklı yazılımlara sahip (v509i: A cihazı, v505p: B cihazı) iki özdeş spektrofotometre (Vita EasyShade V) ile ölçüldü ve CIELAB değerleri kaydedildi (n=260). Spektrofotometrelerin ölçümleri arasındaki renk farkları (∆E00) hesaplandı. Tekrarlanabilirlik değerlendirilmesi için aynı skalanın 3M2 renk tabı, iki spektrofotometre ile ölçüldü (n=50). Cihazların skala ile renk eşleştirme doğruluk oranı hesaplandı. Cihazlar arası güvenilirlik ve cihazlar arasındaki ölçüm farkları, sınıf içi korelasyon katsayısı (ICC), Cronbach’s alfa ve Paired T-testi kullanılarak hesaplandı (α=0.05).
Bulgular: Cihazlar arası güvenilirlik L*, a* ve b* parametreleri için yüksek düzeyde bulunmuştur (ICC>0.99). Renk skalasının ∆E00 değerleri 0.21 ile 1.78 arasında değişmektedir ve skaladaki bütün renklerin ∆E00 değerleri kabul edilebilirlik eşik değerinin altındadır (∆E00<1.8). A cihazının ortalama L* değeri B cihazından önemli derecede yüksek (P<0.001), ortalama a* ve b* değerleri ise önemli derecede düşük bulunmuştur (P<0.001). Tekrarlanabilirlik her iki cihazda a* ve b* parametresi için mükemmel (SD<0.1), L* parametresi için ise biraz daha düşüktür (0.15
