Endodontic Systems Working With Reciprocal Movements For Instrumentation of Root Canals

Kök kanallarının şekillendirilmesinin, başarılı bir endodontik tedavinin en önemli aşamalarından biri olduğu bilinmektedir. Günümüzde kök kanalları genel olarak el ile kullanılan paslanmaz çelik ve/veya nikel-titanyum (Ni-Ti) kanal aletleri ya da bir tork kontrollü motor veya redüksiyonlu anguldruva ile kullanılan Ni-Ti döner alet sistemleri ile şekillendirilmektedir. Ni-Ti döner alet sistemlerinin, avantajlarının yanısıra bazı dezavantajlarının da bulunması, yeni şekillendirme sistemlerinin geliştirilmesine neden olmuştur. Güncel resiprokal hareket ile çalışan sistemlerin; kullanım kolaylıkları, çapraz enfeksiyon risklerinin olmaması, kırılma risklerinin düşük olması ve döner sistemler kadar etkin şekillendirme yapmaları, bu ihtiyacı karşılamada iyi bir alternatif olduklarını göstermektedir. Bu derlemenin amacı,kök kanallarının şekillendirilmesinde resiprokal hareket ile çalışan endodontik sistemler ve bu sistemlerin kullanım özellikleri hakkında bilgi vermek ve bu konudaki çalışma sonuçlarını irdelemektir

Anahtar Kelimeler:

Endodontic Systems Working With Reciprocal Movements For Instrumentation of Root Canals

It has been accepted that instrumentation of the root canals is one of the important steps for the succes of root canal therapy. Contemporarily, the root canals arebeing instrumented with either stainless steel/nickel-titanium (Ni-Ti) handfilesmanually or with rotary Ni-Ti files used with a torque controlleddevice or handpiece. The handycaps in these methods revealed the need for the development of a new instrumentation system in endodontics. The advantages such as simplicity, low risk of cross contamination, efficacy in proper shaping, resistance to cyclic fatique of the recent reciprocating instruments showed that they are a desirable alternative forthat need. In this article, the new reciprocating systems and their clinical useswere introduced, and the findings of the related research articles were presented based on the current literature review
