In terms of obturation techniques, lateral condensation showed statistically the higher percentage filling material than Soft-Core technique in the middle and coronal sections and no statistically significant difference was detected among other groups (p<0.01).Conclusions: According to findings of this study although all filling techniques were found to be effective in oburation of oval shaped canals, lateral condensation technique resulted more gutta-percha & sealer content than Soft-Core technique.

Abstract

Backgraound and Aim: The aim of this study, was to compare the effectiveness of different shaping and filling techniques in oval shaped root canals.Material And Methods: 150 single-root extracted premolar teeth with oval shaped canals were used in this study. The roots were instrumented using the Reciproc system (n:75) or step-back technique (n:75 ) and then, subdivided into five groups according to the filling technique; lateral condensation, Microseal, Obtura, System B, Soft-Core. The specimens were scanned using conebeam computed tomography. Percentage volume of gutta-percha & sealer and void in the coronal, middle, apical thirds of each canal were measured using OnDemad3D-App software program. Results: When shaping techniques were compared, the teeth shaped with step-back technique showed statistically higher percentage of filling material than teeth shaped with Reciproc system (p<0.05). In terms of obturation techniques, lateral condensation showed statistically the higher percentage filling material than Soft-Core technique in the middle and coronal sections and no statistically significant difference was detected among other groups (p<0.01).Conclusions: According to findings of this study although all filling techniques were found to be effective in oburation of oval shaped canals, lateral condensation technique resulted more gutta-percha & sealer content than Soft-Core technique.

Özet

Amaç: Bu çalışmanın amacı, oval şekilli kanallarda farklı şekillendirme ve dolgu teknikleri kullanılarak bu tekniklerin etkinliklerinin karşılaştırılmasıdır. Gereç ve Yöntem: Çalışmada oval kanal varlığı tespit edilmiş 150 adet çekilmiş tek köklü premolar diş kullanılmıştır. Step back tekniği ve Reciproc döner alet sistemi kullanılarak şekillendirilen dişler sonrasında; lateral kondansasyon, Microseal, System B, Obtura ve Soft-Core teknikleri ile beraber kerr kanal patı kullanılarak doldurulup 5 alt guruba ayrılmıştır. Konik ışınlı bilgisayarlı tomografiyle axialden elde edilen görüntülerde her numuneden OnDemand3D-App software programı ile apikal, orta ve koronalden kesitler alınıp bu kesitlerde kanal dolgusu (güta-perka + pat) ve boşluk alanların yüzdeleri hesaplanıp istatistiksel olarak karşılaştırılmıştır. Bulgular: Şekillendirme teknikleri karşılaştırıldığında, stepback tekniği ile şekillendirilmiş dişlerdeki kanal dolgu oranı reciproc tekniğine göre istatistiksel olarak anlamlı derecede yüksek bulunmuştur. Dolgu teknikleri karşılaştırıldığında, lateral kondansasyon tekniği ile doldurulan dişlerde kanal dolgu oranı softcore ile doldurulan dişlere göre orta ve koronal bölgede istatistiksel olarak anlamlı derecede yüksek bulunmuştur. Diğer dolgu teknikleri arasında istatistiksel olarak anlamlı fark bulunmamıştır (p<0.01).Sonuç: Bu çalışmanın bulgularına göre oval şekilli kanalların doldurulmasında tüm dolgu teknikleri başarılı olmasına karşın, lateral kondansasyon tekniği Soft-Core tekniğinden daha yüksek oranda güta-perka ve pat içeriğine sahiptir.
