The aim of this study was to compare the
effectiveness of panoramic, periapical and two different Cone Beam Computed
Tomography (CBCT) devices in the detection of dental caries of dog teeth ex vivo. A total of 880 teeth were
investigated, 33 of which were with caries, whereas; 33 healthy teeth were the
controls. Periapical, panoramic and CBCT scans were made for the assessment of
the teeth. All images were evaluated separately by two observers experienced in
image interpretation. The presence or absence of occlusal caries was scored
using a 5-point scale. Kappa values were calculated to assess intra and
interobserver agreement. Receiver Operating Characteristic (ROC) analysis
was performed to compare the effectiveness of different imaging methods in the
detection of dental caries. For both observers, the order of success of the
image sets in the estimation of the caries tooth was CBCT Morita, CBCT Iluma,
periapical and panoramic radiograph (Area Under Curve (AUC): 0.929, 0.882,
0.861, and 0.704 for observer 1, AUC: 0.927, 0.896, 0.875, and 0.693 for
observer 2, respectively). CBCT was found to be the best
imaging method for the ex vivo detection of caries in dog teeth. In
addition, panoramic images performed worse than all other modalities.

Köpek dişlerindeki çürüklerin tespitinde periapikal, panoramik ve konik ışınlı BT görüntülerinin karşılaştırılması

Bu çalışmanın amacı, ex vivo olarak köpeklerde diş çürüğü tespitinde panoramik, periapikal ve iki farklı Konik Işınlı Bilgisayarlı Tomografi (KIBT) cihazının etkinliğini karşılaştırmaktır. Toplam 880 diş değerlendirilmiş olup 33 çürük diş tespit edilmiştir. Sağlıklı dişlerden rastgele 33’ü seçilerek kontrol grubu oluşturulmuştur. Çürüklerin radyografik olarak değerlendirilmesi için periapikal, panoramik ve KIBT yöntemleri kullanılarak görüntüler elde edildi. Tüm görüntüler, görüntü yorumlamada deneyimli iki gözlemci tarafından ayrı ayrı değerlendirildi. Okluzal çürüğün varlığı veya yokluğu, 5 puanlık bir ölçek kullanılarak puanlandı. Kappa değerleri, gözlemci içi ve gözlemciler arası uyumu değerlendirmek için hesaplandı. Diş çürüğü tespitinde farklı görüntüleme yöntemlerinin karşılaştırılması için ROC analizi yapıldı. Her iki gözlemci için, çürük dişin tespitinde görüntüleme yöntemlerinin başarı sırası KIBT Morita, KIBT Iluma, periapikal ve panoramik radyograf olarak bulunmuştur. (1. gözlemci için Area Under Curve (AUC): 0.929, 0.882, 0.861 ve 0.704, 2. gözlemci için AUC: 0.927, 0.896, 0.875 ve 0.693). KIBT’ın köpek dişlerinde çürüklerin ex vivo tespiti için en iyi görüntüleme yöntemi olduğu belirlenmiştir. Ayrıca, panoramik görüntüler diğer tüm yöntemlerden daha kötü performans göstermiştir.
