N2  - A good apical seal is one of the criteria for the success of the endodontic treatment. The ‎most common causes of failure in endodontic treatment are referred to the lack of proper ‎apical seal. The aim of this in vitro study was to evaluate the apical sealing ability where the ‎canals were prepared by wave one and recipro systems.‎ Material & Method‏:‏ Fifty one extracted human teeth with single root were divided randomly into 3 similar ‎groups of fifteen of each. Group I: the teeth were instrumented with wave one (Dentsply ‎Maillefer, Ballaigues, Switzerland), Group II: the teeth were instrumented with reciproc ‎‎(VDW, Munich, Germany), and group III:  the teeth were instrumented by hand instruments ‎of K-files (Dentsply,maillefer,switzerland); then, the teeth were obturated with lateral ‎condensation techniques. Six teeth were divided as positive and negative control groups; ‎three in each one. AH26 was used as a root canal sealer in this study. A dye penetration ‎method was used to evaluate the apical seal after the longitudinal section, using ‎stereomicroscope at 40X magnification. The data were analyzed using ANOVA and LSD post-‎hoc test at 0.05 level of significance.‎ Results‏:‏ The Lsd statistical analysis of the results demonstrated that there was no statistically ‎significant difference in micro leakage between the two different rotary instruments in each ‎wave one and reciproc. While there was a significant difference between the rotary ‎instruments, and the Hand instrument K-files.‎ Conclusion‏:‏ It could be concluded from this study that the use of the NiTi rotary instrument for root ‎canal preparation showed the least apical micro leakage, in comparison with the hand ‎instrument‎.
