ABSTRACT
Objective: The aim of this
study is to evaluate the influence of different
instrument systems on the amount of extruded debris.
Materials and methods: A total of 30 extracted mandibular molars with two
separate canals and apical foramina in the mesial roots were selected. The root canals (n=10) were randomly
assigned to the six groups of file systems as follows: ProTaper Next (PTN), WaveOne (WO), WaveOne Gold
(WOG), One Shape (OS), Reciproc (R) and
Reciproc Blue (RB). The extruded debris during the instrumentation was
collected into Eppendorf tubes, which were weighed and then stored in an
incubator at 70°C over a period of five days to evaporate the irrigant.
After the incubation process, the Eppendorf tubes were weighed again. The
difference between these two measurements, the first one before and the second
one after the incubation process, was calculated.
Data were statistically analyzed, and the significance level was set at
p<0.05.
Results: R produced less debris compared to
WO. R and PTN files produced significantly less debris compared
to the OS files (p < 0.05). Extruded
debris in RB and WO groups were not significantly different, while RB produced
less debris than WOG and OS (p<0.05).
Conclusions: All instrumentation systems allowed for the apical
extrusion of the debris.
Keywords: Apically extruded debris, Endodontics,
Ni-Ti systems
ÖZ
Amaç:
Bu çalışmanın amacı, farklı
nikel titanyum eğe sistemlerini apikalden taşan debris miktarı açısından değerlendirmektir.
Gereç ve Yöntemler: Bu çalışmada mesial
köklerinde iki ayrı kanal ve apikal foramene sahip toplam 30 adet mandibular
molar diş seçildi. Kök kanalları (n = 10) aşağıdaki altı eğe sistemine göre
rastgele ayrılmıştır: ProTaper Next (PTN), WaveOne (WO), WaveOne Gold (WOG),
One Shape (OS), Reciproc (R) ve Reciproc Blue (RB). İnstrümantasyon sırasında
ekstrüde edilmiş debrisler önceden boş ağırlıkları ölçülmüş eppendorf
tüplerinde toplandı ve sonra irrigantı buharlaştırmak için beş günlük bir süre
boyunca 70 ° C'de bir inkübatörde saklandı. İnkübasyon sürecinden sonra,
eppendorf tüpleri tekrar tartıldı. Bu iki ölçüm arasındaki fark hesaplandı.
Veriler istatistiksel olarak analiz edildi ve anlamlılık düzeyi p <0,05
olarak belirlendi.
Bulgular: R, WO ile
karşılaştırıldığında daha az debris taşmasına sebep oldu. R ve PTN eğeleri, OS
eğelere göre anlamlı derecede daha az debris taşımına sebep oldu (p <0,05).
RB ve WO gruplarında apikalden taşan debris miktarı anlamlı ölçüde farklı
değildi ancak RB WOG ve OS'den daha az debris taşmasına sebep oldu (p
<0.05).
Sonuç:
Bütün eğe sistemleri
apikalden debris taşırmıştır.
