Cone beam computed tomography evaluation of c-shaped canal morphology in mandibular premolar teeth

Elif Aslan, A. Canberk Ulusoy, B. Güniz Baksı, Ali Mert, B. Hakan Şen

Purpose: The aim of this study was to evaluate the prevalence and the morphology of c-shaped root canal(s) in mandibular premolars using cone beam computed tomography (CBCT) images.

Materials and Methods: CBCT images of 1095 mandibular premolars were examined at coronal, middle, and apical levels of the root canals. The type, the level, and the position (buccal or lingual) of the c-shaped anatomy were recorded. Absolute counts and percentages of different groups and subgroups of C-shape morphologies were calculated. The Chi-square test was used to compare the prevalence of C-shaped morphology between mandibular first and second premolars. The Z-test for proportions in independent groups was used to analyze the differences in mandibular C-shaped premolar proportions between location (left and right side) and tooth (first or second premolars) (p=0.05).

Results: c-shaped root canal morphology was present in 44 teeth. The percentage of c-shaped morphologies was 6.9% and 1.6% in mandibular first and second premolars, respectively. Comparison of the first and the second premolars showed that C1 type (p=0.008) and C4b type (p=0.013) configurations are more common in the first premolars at the coronal level. In contrast, the C2 type configuration showed significantly higher prevalence in the second premolars (p=0.009). Additionally, the C4c type configuration was significantly frequent on the right premolars at the coronal level (p=0.038).

Conclusions: C-shape canal morphology is a rare but complex anatomic feature in mandibular premolars. Therefore, clinicians should be aware of this complex root canal anatomy for the success of endodontic treatment in mandibular premolar teeth.

Mandibular premolar dişlerde c-şekilli kanal morfolojisinin konik ışınlı-bt ile değerlendirmesi

Elif Aslan, A. Canberk Ulusoy, B. Güniz Baksı, Ali Mert, B. Hakan Şen

Amaç: Bu çalışmanın amacı, mandibular premolar dişlerdeki C-şekilli kök kanal(lar)ının prevalansının ve morfolojisinin konik ışınlı bilgisayarlı tomografi (KIBT) görüntüleri kullanılarak değerlendirmesidir.

Gereç ve Yöntem: 1095 mandibular premolar dişe ait KIBT görüntüsü koronal, orta ve apikal kök seviyelerinde incelenerek C-şekilli anatominin tipi, seviyesi ve pozisyonu (bukkal veya lingual) kaydedildi. Farklı gruplara ve altgruplara göre C-şekilli morfolojinin dağılımı ve yüzdesi hesaplandı. Mandibular birinci ve ikinci premolar dişler arasında C-şekilli morfolojinin prevalansının karşılaştırılması amacıyla Ki-kare testi kullanıldı. Farklı konum (sol ve sağ) ve diş grupları (birinci ve ikinci premolar dişler) arasındaki C-şekilli morfoloji farklılıklarının analiz edilmesi amacıyla ise Z-testi kullanıldı (p=0,05).

Bulgular: 44 mandibular premolar dişte C-şekilli kök kanal morfolojisi saptandı. Mandibular birinci ve ikinci premolar dişlerdeki C-şekilli morfolojilerin yüzdesi sırasıyla %6,9 ve %1,6 olarak hesaplandı. Birinci ve ikinci premolar dişlerin karşılaştırılması sonucu, birinci premolar dişlerin koronal seviyesinde C1 tipi (p=0,008) ve C4b tipi (p=0,013) konfigürasyonların daha yaygın olduğunu belirlendi. Buna karşılık, ikinci premolar dişlerde ise C2 tipi konfigürasyonun anlamlı olarak yaygın olduğu gözlendi (p=0,009). Ek olarak, sağ premolar dişlerin koronal seviyesinde C4c tipi konfigürasyonun anlamlı derecede sık görüldüğü saptandı (p=0,038).

Sonuç: C-şekilli kanal morfolojisi, mandibular premolar dişlerde nadir olarak izlenen karmaşık bir anatomik varyasyondur. Klinisyenlerin mandibular premolar dişlerde görülen bu karmaşık kök kanal anatomisi hakkında farkındalık sahibi olması, endodontik tedavinin başarısı açısından önem taşımaktadır
