Quantitative Evaluation of Apical Delta Morphologies in Mesial Roots of Mandibular First Molar Teeth:Micro-CT Stud

Öz:

Amaç: Apikal delta ana kök kanalının apeks yakınında veya daha fazla dallanma göstererekaynı zamanda kendisinin radyografide izlenemez hale geldiği dallanmaları tanımlamaktadır. Buçalışmanın amacı mikro--bilgisayarlı tomografi (mikro--BT) kullanarak mandibular birinci molar di--şlerin mezial köklerinin apikal delta morfolojisinin kantitatif analizini yapmaktır. Gereç ve Yöntem--ler: 269 mandibular molar dişin mezial kökleri mikro--BT ile tarandı. İlk taramayı takiben elde edilenyeniden oluşturulmuş mikro--BT görüntülerinden apikal delta saptanan 22 diş seçildi. Apikal dallan--maların sayısı ve vertikal uzunlukları kaydedildi. Her örnekte apikal dallanmaların tespit edildiği enapikaldeki kesit ve dallanmaların ana kanalı oluşturmak üzere birleştiği kesitlerde majör çap, minörçap ve ovallik değerleri ayrı ayrı hesaplandı. Elde edilen veriler tanımlayıcı istatistiklerle analiz edildi.Bulgular: Apikal delta insidansı %13,01 olarak bulundu. Toplamda 96 adet apikal delta dallanmasıkantitatif olarak incelendi. Apikal delta dallanmalarının ortalama sayısı örnek başına 4,45 ve verti--kal uzunluklarının ortalaması 0,95 mm olarak belirlendi. Örneklerin çoğunda apikal delta dallan--malarinin sirküler olmayan bir kesit alanı gösterdikleri saptandı. Sonuç: Apikal deltanın klinikpratiğinde görülme sıklığı azımsanmayacak boyuttadır. Apikal delta dallanmalarının kantitatif ana--lizleri bu varyasyonlarm sayı, şekil ve vertikal uzunlukları açısından çeşitlilik gösterdiğini ortaya koymuştur. Bu apikal delta dallanmalarının kompleks anatomisi kök kanal sisteminin üç boyutluşekillendirilmesi ve doldurulmasını zorlaştırabilir.

Mandibular Birinci Molar Dişlerin Mezial Köklerindeki Apikal Delta Morfolojisinin Kantitatif İncelenmesi: Bir Mikro-BT Çalışması

Öz:

Objective: The apical delta is the branching of the main root canal dividing into three ormore ramifications near the root apex, while the main canal itself becoming indistinguishable. Aimof this study was to analyze apical delta morphologies of mesial root canals of mandibular first molarteeth quantitatively using micro--computed tomography (micro--CT). Material and Methods: Two hun--dred and sixty--nine mesial roots of mandibular first molar teeth were scanned by micro--CT. ollow--ing the initial scanning, 22 specimens showing apical delta ramifications were selected fromreconstructed micro--CT images. The numbers and vertical extension of the apical ramifications wererecorded. For each specimen, major diameter, minor diameter and roundness values at the most api--cal slices of the apical delta ramifications and at the slice where ramifications merged to form to maincanal were calculated. Data were analyzed using descriptive statistics. Results: The incidence of api--cal delta was 13.01%. total of 96 apical delta ramifications were quantitatively analyzed. The meannumber of apical delta ramifications was 4.45 per specimen and the mean vertical extension was 0.95mm. Majority of the apical delta ramifications exhibited noncircular cross sectional shape. Conclusion:The occurrence of apical delta is not uncommon in clinical practice. The shape, number and the heightof the apical delta are variable. These complex morphological properties of apical delta might com plicate three--dimensional shaping and obturation of root canal systems.
