Abstract

Amaç: Sodyum hipoklorit (NaOCl), klorin dioksit (ClO2), etilen diamin tetra asetik asit (EDTA) ve etidronik asit (HEDP) solüsyonlarının One Curve (OC) eğesinin döngüsel yorulma direncine etkisini değerlendirmektedir.
Gereç ve Yöntemler: 60 adet OC eğesi %5 NaOCl, %3,5 ClO2, %17 EDTA, %18 HEDP solüsyonu ve distile su ile muamele edilmek üzere 5 gruba (n= 12) ayrıldı. Her grupta bulunan eğeler kanal içi sıcaklığa (35±1 °C) getirilmiş ilgili solüsyonlara daldırılarak 5 dk bekletildi. Ardından eğeler 60° kurvatür açısına, 5 mm yarıçapına ve 1.5 mm çapına sahip 17 mm uzunluğunda paslanmaz çelik blokta test edildi. Eğeler X-Smart Plus endomotor ile kırılıncaya kadar kullanıldı. Eğelerin kırılana kadar olan tur sayıları ve süreleri ve kırık parça uzunlukları kaydedildi. P<0,05 anlamlılık derecesinde verilerin istatistiksel analizi için tek yönlü varyans analizi ve Tukey testi kullanıldı.
Bulgular: Eğelerin döngüsel yorgunluk direnci arasında istatistiksel olarak fark gözlenmedi (P>0,05). Kırık parça uzunlukları büyükten küçüğe sırasıyla; distile su, HEDP, EDTA, NaOCl, ClO2 olarak bulundu. Test edilen solüsyonlar kırık parça uzunlukları açısından anlamlı fark gösterdi (P<0,05).
Sonuç: Test edilen tüm solüsyonlar OC eğesinin döngüsel yorgunluk direnci üzerinde benzer etki sergilemiştir. Bununla birlikte kırık parça uzunluğu en uzun distile su grubunda iken, en kısa ClO2 grubunda bulunmuştur.

Comparison of the Effect of Endodontic Irrigation Solutions on the Cyclic Fatigue Resistance of the One Curve File: An In Vitro Study

Abstract

Aim: Evaluate the effects of sodium hypochlorite (NaOCl), chlorine dioxide (ClO2), ethylene diamine tetra acetic acid (EDTA) and etidronic acid (HEDP) on the cyclic fatigue resistance of the One Curve (OC) file. Materials and Methods: 60 OC files were divided into 5 groups (n= 12) to be treated with 5% NaOCl, 3,5% ClO2, 17% EDTA, 18% HEDP and distilled water. The files were immersed in the relevant solutions in temperature (35±1 °C) for 5 minutes. Stainless-steel block with 17 mm long an angle 60° and an inner diameter of 1.5 mm was used. X-Smart Plus endomotor was used until files were broken. The number of cycles, elapsed time and the lengths of broken fragments were recorded. One-way analysis of variance and the Tukey test were used for statistical analysis (p<0,05). Results: No statistical difference was observed between the cyclic fatigue resistance of the files (p>0,05). Broken fragment lengths, in order from largest to smallest; distilled water, HEDP, EDTA, NaOCl, and ClO2 (P<0,05). Conclusion: All tested solutions exhibited similar effects on OC file. The longest fractured fragments length was found in the distilled water group, while the shortest was found in the ClO2 group.
