Radyografik çürük tanısında intraoral filmler ve dört fosfor plaka sisteminin in vitro karşılaştırılması
Amaç: Radyografide çürük tanısının konması bazen kolay olmayabilir. Bu çalışmada aynı şartlar altında değerlendirilen dört adet fosfor plaka sisteminin ve iki film esaslı sistemin çürük tanısındaki yerinin araştırılması amaçlanmıştır.Yöntem: İki yüz adet diş beşerli gruplar halinde plastik Lego® bloklara yerleştirildi. Her bir bloktan standart şartlarda dental röntgen apareyi ile radyografik görüntü alındı. Fosfor plakalarla (Dentsply DenOptics®, Dürr Vistascan II®, Soredex Digora FMX®, Soredex Digora Optime®) 60 kV ve 7 mA ışınlamayla görüntü elde edildi. Çürük derinliği on bir gözlemci tarafından değerlendirildi. Histolojik bulguları karşılaştırmak için mikroskobik inceleme yapıldı. Mikroskobik ve radyolojik bulgular arasındaki farklar değerlendirilerek çürük derinliği belirlendi. Bulgular: Çürük tanısında farklı sensörlerin çok az etkisi olduğu görüldü. En büyük farkı DenOptix ve Digora FMX sistemleri gösterdi. Tüm yüzeyler hesaplandığında etkinin istatistiksel olarak anlamlı olmadığı bulundu. Sonuç: Dört fosfor plaka sistemi de çürük tanısında kabul edilebilir sonuçlar göstermiştir. Mine çürüğündeki histolojik derinlik radyografik ölçümlerle uyumlu bulunmamıştır.

In vitro comparison of intraoral films and four image plate systems in radiographic caries diagnosis
Objectives: Detecting early caries lesion on a radiograph may be a difficult task. The aim of this study was to compare four image plate and two film-based systems by evaluating the accuracy of caries detection under standard conditions. Methods: Two hundred teeth were attached in groups of five onto plastic Lego®blocks. Radiographs were taken from each block under standard bitewing conditions with an X-ray device. Phosphor plates (Dentsply DenOptics®, Dürr Vistascan II®, Soredex Digora FMX®, Soredex Digora Optime®) were exposed at 60 kV and 7 mA. The caries depths were analyzed by eleven observers and microscopic investigation was used to compare the histological findings. The caries depth was calculated as the difference between microscopic and radiological findings. Results: Data analysis showed a small impact of different sensors on the diagnostic accuracy. The largest differences between microscopic and radiographic caries ratings were found with DenOptix and Digora FMX. When it was calculated over all surfaces no statistical significance was found. Conclusion: The results suggest that the performance of the four storage phosphor image plate systems is acceptable for the detection of caries. The increase in histological depth of enamel caries was not significantly correlated with radiographic measurements.
