Abstract

Amaç: Bu çalışmada, resiprokal tek eğe, tam rotasyon tek eğe ve çok basamaklı eğe sistemleriyle şekillendirme öncesi kayma yolu hazırlığının apikalden debris çıkışına ve kök kanalının yer değiştirmesine üzerindeki etkisinin araştırılması amaçlanmıştır.
Gereç ve Yöntem: Mandibular birinci molar dişlerin yüz yirmi eğimli meziyal kök kanalı rastgele altı gruba dağıtıldı (n=20). Kök kanalları Grup R'de Reciproc, Grup OS'de OneShape ve Grup PN'de ProTaper Next ile hazırlandı. Son üç grupta (RG, OSG ve PNG), ilk 3 grupta kullanılan şekillendirme aletlerinden önce bir kayma yolu oluşturuldu. Preparasyon öncesi ve sonrası ağırlık 10-5 mikro terazi kullanılarak ölçülmüştür. Kök kanallarının preparasyonu öncesi ve sonrası konik ışınlı bilgisayarlı tomografi (KIBT) kullanılarak tarandı.
Bulgular: RG ve OSG'deki debris ekstrüzyonu, sırasıyla R ve OS gruplarından önemli ölçüde daha yüksekti. Ancak, PN ve PNG arasında anlamlı fark bulunmadı. Kök kanal yer değiştirmesine bakıldığında, RG, 5 mm ve 7 mm seviyeleri için R grubundan daha düşüktü ve OSG grubu tüm seviyeler için OS'den daha düşüktü. Bir kayma yolu oluşturmak, OS ve PN grupları için şekillendirme süresini önemli ölçüde arttırmıştır.
Sonuç: Eğimli kanallarda tek eğe sistemi ile şekillendirme öncesinde bir kayma yolu oluşturmak kanal anatomisini korur. Bununla birlikte, apikal debris ekstrüzyonunun artmasına neden olabilir.

Influence of establishing a glide path on the amount of apically extruded debris and the preservation of root canal anatomy

Abstract

Purpose: This study aimed to investigate the effect of glide path preparation before shaping with reciprocating single-file, rotary single-file and multiple-file systems on the debris extrusion from the apical, and on the root canal transportation.
Materials and Methods: One hundred twenty curved mesial root canals of mandibular first molars were randomly distributed to six groups (n=20). The root canals were prepared with Reciproc in Group R, OneShape in Group OS, and ProTaper Next in Group PN. In the last three groups (RG, OSG and PNG), a glide path was created before the shaping instruments used in the first 3 groups. The pre- and post-preparation weight were measured by using a 10-5 microbalance. Pre- and post-preparation of the root canals were scanned by using cone-beam computed tomography (CBCT).
Results: The debris extrusion in RG and OSG was significantly higher than R and OS, respectively. However, no significant differences were found between PN and PNG. Considering the root canal transportation, RG showed lower than R for 5 mm and 7 mm levels and the OSG group showed lower than OS for all levels. Creating a glide path significantly increased the shaping time for OS and PN groups.
Conclusion: In advance of shaping with a single-file system in curved canals, creating a glide path preserves canal anatomy. However, it may lead to increase apical debris extrusion.
