Abstract

Amaç: Aşırı eğimli kök kanallarında
iki farklı döner sistem eğeleri ile kök kanalı şekillendirme etkinliğini
karşılaştırmak.

Gereç ve Yöntemler: Otuz adet aşırı eğimli (38.96±12.89)
mandibular birinci molar dişler çalışmaya dâhil
edildi. Eşit olarak iki gruba ayrılan dişlerin çalışma boyu ve kanal
devamlılığı tespit edildi. Düşük hızlı testere yardımı ile dişlerin
apikal, orta ve koronal seviyelerinden kesitler alındı. Şekillendirme sırasında Bramente ve ark. (1987) belirttiği gibi
mufla sisteminden faydalanıldı. Kesitlerden dijital görüntüler şekillendirme
öncesi ve sonrasında stereo mikroskop (x40) ile alındı.
Mufla sistemine sırasıyla yerleştirilmiş olan kesitlerde Revo-S ve
Lightspeed-LSX eğeleri ile apikal genişlik 40 olacak şekilde genişletildi.
Merkezde kalma oranı, şekillendirilmiş alan, şekillendirilmemiş alan ve
transportasyon dijital görüntülerin öncesi ve sonrasında üst üste monte
edilerek ölçüldü. Bağımsız t testi, One-way ANOVA ve post-hok Tukey testi
uygulanmıştır (P<0.05).

Bulgular: Merkezde kalma oranı ortalama Revo-S
0,23±0,12 ve Lightspeed LSX için 0,13±0,08. Apikalde Revo-S (0.26 mm²)
Lightspeed-LSX (0.15 mm²)’e göre dentin alanı kaldırması daha fazla
olmuştur (P<0.05). Şekillendirilmemiş alanda Revo-S ve Lightspeed-LSX için
istatistiksel olarak anlamlı farklılıklar gözlenmiştir: servikal (% 21.52 ve
7.28), orta (% 23.66 ve 6.00) ve apikal (% 17.68 ve 5.41) (P<0.05).

Sonuçlar: Lightspeed LSX’ in Revo-S’ e göre daha merkezi kök kanalı
şekillendirmesi yaptığı görülmüştür.
