Objective: The aim of this study was to evaluate the prevalence, symmetry, configuration, and radicular groove type of Cshaped canals in mandibular first and second molars in a group of Turkish populations using cone-beam computed tomography (CBCT) images. Material and Methods: CBCT images of 442 (202 males and 240 females) patients, mandibular first and second molars were examined. The roots of the teeth were analyzed using axial sections in three different regions as coronal, middle and apical. The presence and classification of C-shaped canal configuration was evaluated in four categories according to the criteria of Fan et al. Also, the presence and classification of the radicular groove was assessed in three categories: buccal, lingual and buccal-lingual. Data analyzed by chi-square test. Results: While C-shaped canal configuration wasn't observed in first molars in the Turkish subpopulation, the frequency of ''C'' shape in lower second molars was determined as 6.94%. The presence of Cshaped canals was found to be higher in women than in men (p<0.05). In mandibular second molars, C-shaped canals were seen more frequently on the left side (65.96%). The prevalence of C1 canal configuration in the coronal (44.68%) and C4 configuration in the apical third (51.06%) was found to be significantly higher (p<0.05). The most common radicular groove type was determined to be the lingual groove with a prevalence of 74.47%. Conclusion: Gender and side factors seem to be effective in the variation of the C-shaped canal. Therefore, 3-dimensional evaluation of tooth morphology with CBCT is very important in terms of treatment planning and prognosis prediction.

Amaç: Bu çalışmanın amacı, bir grup Türk popülasyonunda mandibular birinci ve ikinci molar dişlerdeki ''C'' şeklindeki kanalların prevalansını, simetrisini, konfigürasyonunu ve radiküler oluk tipini konik ışınlı bilgisayarlı tomografi (KIBT) görüntüleri kullanarak değerlendirmektir. Gereç ve Yöntemler: Çalışmada 442 (202 erkek ve 240 kadın) hastada, mandibular birinci ve ikinci molar dişlerin KIBT görüntüleri incelendi. Dişlerin kökleri koronal, orta ve apikal olmak üzere üç farklı bölgede aksiyal kesitler kullanılarak analiz edildi. ''C'' şeklindeki kanal konfigürasyonunun varlığı ve sınıflandırılması, Fan ve ark.nın kriterlerine göre dört kategoride değerlendirildi. Ayrıca radiküler oluğun varlığı ve sınıflandırılması bukkal, lingual ve bukkallingual olmak üzere üç kategoride değerlendirildi. Veriler ki-kare testi ile analiz edildi. Bulgular: Türk subpopülasyonunda birinci molar dişlerde ''C'' şeklinde kanal konfigürasyonu bulunmazken mandibular ikinci molar dişlerde ''C ''şeklinin görülme sıklığı %6,94 olarak belirlendi. ''C ''şekilli kanal varlığı kadınlarda erkeklerden daha yüksek bulundu (p<0,05). Mandibular ikinci molar dişlerde ''C'' şekilli kanal sol tarafta daha sık görüldü (%65,96). Koronalde C1 kanal konfigürasyonunun (%44,68) ve apikal üçlüde C4 konfigürasyonunun (%51,06) prevalansı anlamlı olarak yüksek bulundu (p<0,05). En sık görülen radiküler oluk tipi %74,47 prevalans ile lingual oluk olarak tespit edildi. Sonuç: C şeklindeki kanalın varyasyonunda cinsiyet ve simetri faktörlerin etkili olduğu görülmektedir. Bu nedenle KIBT ile diş morfolojisinin 3 boyutlu değerlendirilmesi, tedavi planlaması ve prognoz tahmini açısından çok önemlidir.
