Abstract

Objective: The purpose of this retrospective study was to compare the correlation between digital panoramic radiography (DPR) and cone-beam computed tomography (CBCT) evaluations for localization of impacted permanent maxillary canines (IPMCs) and for other qualitative and quantitative parameters.

Materials and Method: DPR and CBCT images of 60 patients (17 men and 43 women) were examined independently by two observers. Correlations between DPR and CBCT images were evaluated regarding qualitative (bucco-palatal positioning of IPMCs, morphology and presence of root resorption of adjacent permanent lateral incisors, and contact relationship between IPMCs and adjacent permanent lateral incisors) and quantitative (angle measurements) variables. All evaluations were repeated 1 month later by each observer. Chi-square and t-tests were used for statistical analysis. Kappa statistics were used to assess intra- and interobserver agreement (Cohen’s κ).

Results: No correlation was observed for determination of bucco-palatal positioning of IPMCs between DPR and CBCT images (p>0.05). Correlations were observed for other qualitative variables (p<0.05). Differences between DPR and CBCT images were seen for all examined quantitative variables (p<0.01). Intra- and interobserver agreements were substantial to almost-perfect.

Conclusion: No significant correlation was found between DPR and CBCT images for determination of bucco-palatal positioning of IPMCs. All quantitative measurements performed on DPR and CBCT images significantly differed from each other.

Abstract

Amaç: Bu retrospektif çalışmanın amacı; gömülü daimi maksiller kanin dişlerin lokalizasyonunun belirlenmesinde, ve diğer nitel ve nicel değişkenler için, dijital panoramik radyografi (DPR) ve konik-ışınlı bilgisayarlı tomografi (KIBT) görüntülerinde yapılan değerlendirmeler arasındaki uyumluluğun karşılaştırılmasıdır.

Gereç ve Yöntem: Çalışmada 60 hastanın (43 kadın ve 17 erkek) DPR ve KIBT görüntüleri iki gözlemci tarafından, birbirinden bağımsız olarak incelendi. DPR ve KIBT görüntüleri arasındaki ilişki, nitel (gömülü daimi maksiller kanin dişlerin bukko-palatal yöndeki lokalizasyonu, komşu daimi lateral kesici diş kökünde rezorpsiyon varlığı, gömülü daimi maksiller kanin dişler ve komşu daimi lateral kesici arasındaki kontakt ilişkisi) ve nicel değişkenler (açı ölçümleri) yönünden değerlendirildi. Veri istatisksel olarak ki-kare ve t-testleri ile analiz edildi. Gözlemci içi ve gözlemciler arası uyum Kappa istatistiği ile incelendi (Cohen’s κ).

Bulgular: Gömülü daimi maksiller kanin dişlerin bukko-palatal yöndeki lokalizasyonunun belirlenmesinde DPR ve KIBT görüntüleri arasında istatistiksel olarak anlamlı bir korelasyon bulunamadı (p>0.05). Diğer nitel değişkenler için DPR ve KIBT görüntüleri arasında istatistiksel olarak anlamlı korelasyon vardı (p<0.05). Tüm nicel değişkenler için DPR ve KIBT görüntüleri arasında istatistiksel olarak anlamlı fark bulundu (p<0.01). Yapılan tüm incelemelerde gözlemci içi ve gözlemciler arası değerlendirmeler tutarlı bulundu.

Sonuç: Gömülü daimi maksiller kanin dişlerin bukko-palatal yöndeki lokalizasyonunun belirlenmesinde DPR ve KIBT görüntüleri arasında anlamlı bir korelasyon bulunamadı. DPR ve KIBT görüntüleri üzerinde yapılan tüm nicel ölçümler birbirinden belirgin bir şekilde farklılık gösterdi.
