Introduction A glide path, smoothly centered from the canal orifices to the physiological terminus, facilitates root canal preparation with Ni-Ti instruments by monitoring the tip of the first rotating instrument.1-3 During root canal preparation, complications such as taper lock, instrument fracture, and shaping aberrations, can be prevented by creating a glide path.2-4,5 Some studies have shown that the debris extrusion decreases, and the postoperative pain is less after using the pathfile.6 Although it is well established that all canal preparation techniques cause apical debris extrusion, the effect of the preparation technique on the amount of extruded debris continues to be studied.7 There are conflicting results regarding this issue; for example, Cakici et al8 and De-Deus et al9 demonstrated that the reciprocating system resulted in reduced apical extrusion of debris. According to the metaanalysis of Pedrina et al,11 the reciprocating system gave rise to more successful results in molar teeth than continuous rotation systems. The WaveOne Gold Glider has an 0.15-mm diameter tip and variable 2-6% taper with maximum flute diameters of D1 = 0.170 mm, D8 = 0.413 mm, and D16 = 0.850 mm.16 This study purposed to evaluate the impact of reciprocating and rotary single glide path instruments on the amount of debris extrusion and preparation time during root canal shaping with WaveOne Gold in curved mesial root canals of mandibular molars. [...]the total preparation time was recorded for each tooth.
