Aim: The purpose of this study was to Compare Progressive changes in canal shape after using Reciprocatory - WaveOne and Reciproc and Rotary- One Shape Single File Systems with Protaper Next Multiple File System in mesial mandibular first molar by using cone beam computed tomography with and without glide path preparation.

Methodology: One hundred twenty freshly extracted mandibular first molar human teeth severely curved mesial root with two separate canals i.e. mesiobuccal and mesiolingual and apices with a curvature angles ranging within 20-30 degrees were divided into twol into two groups[ n = 60 each] Group I: With Glide Path;Group II: Without Glide Path.The two groups were then subgrouped into four subgroups [ n=15 each] and the mesial canals were then prepared with four diffd different file systems using WaveOne, Reciproc, One Shape and Protaper Next file instrumentation systems in strict accordance with each manufacturer's recommendations. CBCT images were obtained before and after instrumentation with glide path at 90high resolution dental mode. The technical outcomes were then compared at technical 0, 1, 2, 3,4, 5,6 and 7mm intervals to evaluate the progressive changes in canal shape after using reciprocatory and rotary single file systems with Protaper Next multiple file system. The obtained results were statistically analyzed using t-test and Chi-square.

Results: Using t-test and Chi-square test there was a statistical difference between the root canal curvatures and working time be- orking time between the two groups (P < 0.05). Glide path is necessary for both multiple and single file systems and for rotary and reciprocatory motion in order to achieve a path so that files can enter from the orifice and follow the smooth canal walls uninterrupted to the terminus. Protaper Next Multiple File System showed the better cleaning and shaping ahility with recnect to all the narameters ability with respect to all the parameters and with. evaluated in this study both with and without glide path followed by ReciprocatingWaveOne, Reciproc and the Rotary- One Shape - Single File Systems.

Conclusion: Within the limits of this study Protaper Next appeared to besuitable instrument used both with and without creation of glide path.
