Abstract

Introduction: To examine the amount of apically extruded debris produced by different rotary systems in curved root canals and tofind out the effect of gravitational forces on extrusion. Methods: Ninety-six severely curved root canals were instrumented with; Twisted File Adaptive (SybronEndo, Orange, CA, USA),WaveOne (Dentsply Maillefer, Ballaigues, Switzerland), ProTaper Next (Dentsply Maillefer) and Mtwo (VDW, Munich, Germany)systems. Each group was divided into two subgroups of maxillary and mandibular considering their location and a trial model wasused as a phantom head to simulate the upper and lower jaws. The amount of extruded debris was weighed using a 10-5 microbalance. Results: The location of the tooth and the instrument used had no significant effect on the amount of extrusion (p> 0, 05). When thegravitational force was considered regardless of the instruments, significantly more debris was extruded in teeth with mandibularlocation (p< 0, 05). Discussion and Conclusion: All rotary instruments caused apical extrusion of debris. Instrument technique and gravity has no impacton the amount of extruded debris.

Özet

Giriş ve Amaç: Farklı döner eğe sistemleri ile genişletilen kanallardaki apikal debris ekstrüzyonunu incelemek ve yer çekimininetkisini belirlemek Yöntem ve Gereçler: Doksan altı adet eğimli kök kanalı; Twisted File Adaptive, WaveOne, ProTaper Next ve MTwo sistemleri ilegenişletildi. Her grup alt ve üst çene grupları olmak üzere iki alt gruba ayrıldı ve alt ve üst çeneyi taklit eden deneysel bir düzenekkullanıldı. Taşan debris miktarı 10-5 hassasiyetinde hassas tartı ile ölçüldü. Bulgular: Diş pozisyonlarının, eğe sistemleri üzerine apikalden taşan debris miktarı açısından anlamlı bir etkisi görülmedi (p> 0, 05).Ancak eğelerden bağımsız olarak değerlendirildiğinde alt çene pozisyonunda daha fazla debris taştığı gözlemlendi (p< 0, 05). Tartışma ve Sonuç: Tüm eğe sistemlerinde apikalden belli miktarda debris taştığı görüldü. Eğe sistemleri ve yer çekiminin apikaldentaşan debris üzerine etkisi gözlenmedi.
