Up till now, there are no clinical studies on the effect of instrumentation using TruNatomy files on post-operative pain. Furthermore, these newly introduced files can provide more affordable means for instrumentation. Therefore, the purpose of this study is to clinically compare the effect of using TruNatomy files and HyFlex EDM files on post-operative pain.
The aim of the present study is to clinically compare the incidence of postoperative pain after root canal preparation using TruNatomy system and HyFlex Electrical Discharge Machined (EDM) rotary system in asymptomatic necrotic mandibular molars.
