İki Farklı Obturasyon Tekniği ile Doldurulan Kök Kanallarından Güta-perka Uzaklaştılmasında XP-endo Finisher R ve Er: YAG Lazer ile PIPS Tekniğinin Etkisi.

Abstract

Arka plan: Bu çalışmanın amacı, iki farklı obturasyon tekniği ile doldurulan kök kanallarında güta-perka çıkarılmasında Er: YAG lazer kullanılarak PIPS tekniğinin ve XP-endo Finisher R eğesinin etkinliğini karşılaştırmaktır. Yöntemler: Altmış tek köklü dişin kök kanalları X3'e kadar (Dentsply, Ballaigues, İsviçre) ProTaper Next Rotary aletleri ile şekilledirildi. Kök kanallarının yarısı soğuk lateral kondenzasyon tekniği ile diğer yarısı System B tekniği (Kerr Corporation, CA, ABD) ile dolduruldu ve tüm gruplarda kök kanal patı olarak BioRoot RCS patı (Setodent, Louisville, ABD) kullanıldı. Bir hafta sonra tüm kök kanallarından Protaper Universal retreatment eğeleri (Dentsply, Ballaigues, İsviçre) kullanılarak gutta perka uzaklaştırıldı ve kök kanalları çalışma uzunluğunda ProTaper Next X5’ kadar şekillendildi. Her iki grup da ek temizleme yöntemlerine göre 3 alt gruba ayrıldı: Ek temizleme yöntemi olmayan kontrol grubu, XP-endo Finisher R veya Er:YAG lazer kullanılarak PIPS tekniği. Son olarak tüm dişler uzunlamasına ayrıldı ve operasyon mikroskobu (Carl Zeiss, Heidelberg, Almanya) kullanılarak görüntüler alındı. Görüntüler Image J programı ile analiz edildi. İstatistiksel analiz için iki yönlü ANOVA ve Tukey testleri kullanıldı. Bulgular: Güta perka uzaklaştırılmasında uygulanan kanal doldurma teknikleri arasında istatistiksel olarak anlamlı fark vardı (p=0.010). Ek temizleme yöntemleri arasında anlamlı bir fark yoktu (p=0,196). Sonuç: Bu çalışmanın sınırları dahilinde System B tekniği ile doldurulan kök kanallarında güta perka uzaklaştırmak daha zordur. Kanal dolgu malzemelerinin çıkarılmasında ek temizleme yönteminin kullanılması etkili olmamıştır.

The Effect of XP-endo Finisher R and PIPS Technique Using Er: YAG Laser on Removal of Gutta-percha in Root Canals Obturated with Two Different Obturation Techniques

Abstract

Background: The aim of this study is to compare the efficacy of XP-endo finisher R file and PIPS technique using Er: YAG laser on removal of gutta-percha in root canals obturated with two different obturation techniques. Methods: The root canals of sixty single-rooted teeth were prepared with ProTaper Next Rotary instruments up to X3 (Dentsply, Ballaigues, Switzerland). Half of the root canals were obturated with cold lateral condensation technique and the other half with System B technique (Kerr Corporation, CA, USA) and BioRoot RCS sealer (Setodent, Louisville, USA) was used in all groups as a root canal sealer. After one week, all root canals were retreated using Protaper Universal retreatment instruments (Dentsply, Ballaigues, Switzerland) and enlarged to ProTaper Next X5 File at the working length. Both groups were divided into 3 subgroups according to the additional cleaning methods: control group without an additional cleaning method, XP-endo Finisher R or PIPS technique using Er: YAG laser. Finally, all teeth were split longitudinally and images were taken using an operation microscope (Carl Zeiss, Heidelberg, Germany). The images were analyzed by Image J program. Two-way ANOVA and Tukey tests were used for statistical analysis. Results: There was a statistically significant difference between the canal filling techniques applied in the evaluation of remnants (p=0.010). There was no significant difference between additional cleaning methods (p=0.196). Conclusion: Within the limitations of this study, cleanliness is more difficult in root canals obturated with System B technique. Use of additional cleaning method was not effective in removal of root canal filling materials.
