Giriş Alt çene azı dişleri, karmaşık radix entomolaris veya c şeklindeki kök kanallarının varlığı gibi karmaşık anatomik yapıları nedeniyle kök kanal tedavilerinin başarısız olduğu en yaygın diş gruplarından biridir. Bu dişlerin uzun dönem başarısı için tüm anatomik varyasyonların iyi bilinmesi gerekir. Bu çalışmanın amacı, bir grup Türk hastada konik ışınlı bilgisayarlı tomografi (KIBT) görüntülerini inceleyerek alt çene azı dişlerinin kök sayısını ve kök kanal anatomisini değerlendirmektir.
Gereç ve Yöntemler Toplam 280 hastanın 936 alt birinci ve ikinci mazı dişlerinin KIBT görüntüleri değerlendirildi ve bu dişlerde kök sayısı, kök kanal anatomisi, radix entomolaris ve c şekilli kök kanallarının görülme sıklığı değerlendirildi. Hastaların cinsiyeti ve yaşı da kaydedilerek aralarındaki olası korelasyonlar araştırıldı.
Sonuçlar Toplam 936 alt azı dişinin %98.8' inde iki kök vardı ve %1'inde radix entomolaris mevcuttu. Dişlerin %79.7' sinde 3, %17.7'sinde 4 ve %2.7'sinde 2 kök kanalı vardı. Alt ikinci azı dişlerinin %6,6'sında C-şekilli kök kanal oluşumu görüldü. Alt ikinci azı dişlerinin mezyal kökleri için tek kanal (Vertucci tip I) görülme oranı %4,7 iken, alt birinci azı dişlerinin distal kökleri %30,3 oranında tip IV oluşum gösterdi.
Sonuç Bulgularımızın klinik pratiğe katkısı göz önüne alındığında, alt ikinci azı dişlerinde C şeklindeki kanalların görülme sıklığı %6,6 idi. Radix entomolaris, tüm dişlerin %1'inde mevcuttu. Alt azı dişlerinin %17.7' sinde dört kök kanalı tespit edildi.

Assessment of the Canal Anatomy of the Mandibular Molars in a Group of Turkish Patients: A Cone-Beam Computed Tomography Study

Öz

Objective: The mandibular molars represent one of the most common dental groups in which root canal treatments fail due to their complex anatomical structure and presence of the radix entomolaris or c-shaped root canals. For the long-term successful treatment of these teeth, all anatomical variations should be well known. The aim of this study was to evaluate the number of roots and root canal anatomy of mandibular molars in a group of Turkish patients by examining cone-beam computed tomography (CBCT) images.
Material and Method: The CBCT images of 936 mandibular first and second molars of a total of 280 patients were evaluated, and the number of roots, root canal anatomy, and incidence of the radix entomolaris and c-shaped root canals in these teeth. The patients’ gender and age were also recorded, and their possible correlation with the dental data was investigated.
Results: Among the total 936 mandibular molars, 98.8% had two roots, and the radix entomolaris was present in 1%. The number of root canals was 3 in 79.7% of the teeth, 4 in 17.7%, and 2 in 2.7%. Of the mandibular second molars, 6.6% showed C-shaped root canal formation. The rate of a single canal (Vertucci type I) was 4.7% for the mesial roots of the second molars, while the distal roots of the mandibular first molars showed type IV formation at a rate of 30.3%.
Conclusion: Considering the contribution of our findings to clinical practice, the incidence of C-shaped canals in the mandibular second molars was 6.6%. Radix entomolaris was present in 1% of all the teeth. Four root canals were detected in 17.7% of the mandibular molars.
