Materials and Methods This study was conducted using simulated root canals (n = 40). The specimens were divided into four experimental groups (n = 10 each). Each group prepared by NiTi system as following: ProTaper Universal, ProTaper Next, and WaveOne, the canals were injected with black ink before instrumentation, a series of p...
