    Author(s): Khanda Ali Kareem* and Shakhawan Kadir Kadir

    Background: To guarantee effective endodontic therapy, any smear layer that forms as a result of the debridement of dentinal walls must be eliminated, as it may reduce the overall efficacy of therapy. Aims: This study aims to evaluate the smear layer removal of TruNatomy (TRN), Protaper Next (PTN), and Dia-X systems. Thirty extracted mandibular premolars with a single canal were chosen. The teeth were randomly divided into three groups of 10 specimens based on the type of rotary file used for instrumentation: (1) TruNatomy (TRN) system, (2) Protaper Next (PTN) system, and (3) Dia-X system. Samples were irrigated with 5.25 percent NaOCl and Normal saline. Then samples were analyzed using a Scanning Electron Microscope (SEM) at a magnification of 2000x at the center of the coronal, middle, and apical areas. Statistical analysis of the data was conducted using the Kruskal-Wallis and Mann.. Read More»
