Evaluation Of Effect Of Root Canal Irrigating Solutions On The Cyclic Fatigue Resistance Of Rotary Nickel-Titanium File – An In-Vitro Study
نویسندگان
چکیده
Aim- The aim of this in-vitro study was to compare the effect NaOCl, EDTA, Propolis and Distilled water on cyclic fatigue resistance Protaper Gold rotary NiTi instruments.
 Method- A total 40 commercially available (n =40) Ni-Ti files were used assess different root canal irrigants their resistance. divided into four groups (n=10 per group) as Group 1- (Control group), 2 – 5.25 % 3 -17% EDTA 4 - Propolis. instruments rotated in custom-made stainless steel artificial (angle 60˚and 5 mm radius), fixed a glass container with irrigating solution until instrument fractured. time fracture registered for each number cycles (NCF) calculated statistical analysis done.
 Result- 1 (Distilled water) exhibited best (1386.50±37.12) amongst all tested followed by (Propolis) (EDTA). (5.25 NaOCl) showed least (971.50 ± 48.879) compared other (P>0.05). 
 Conclusion- when distilled NaOCl significantly deteriorated surface characteristics files.
