With the advancements been made in Nickel Titanium (NiTi) rotary files to decrease complications during root canal treatment, however, different irrigation solutions are being used during the procedure that might affect the cyclic fatigue resistance of instruments. In this study effect of irrigation solutions on NiTi was compared.
A total of 30 files were divided into three groups of sodium hypochlorite, EDTA and normal saline, each group containing 10 files. After the immersion the files were rotated inside a custom-made block until the files were fractured.
According to t-test group II (EDTA) showed maximum mean time taken until fracture and least mean time in case of Group I (sodium). however according to ANOVA test no significant difference between the experimental groups were found.
Within the limitations of this study, EDTA had the least effect while sodium had the greatest effect on cyclic fatigue of the instruments.
