Debridement Ability of TruNatomy, S-One Plus, and Other Single File Systems

BACKGROUND: Rotary nickel titanium instrument are an essential part of endodontic treatment, it is important to compare the root canal cleaning ability these instruments. AIM: This study aimed amount smear and debris layer remained following use four rotary instruments with irrigant solution: TruNatomy (TRN), Protaper Next (PTN), S-One Plus Wave One Gold (WOG). METHODS: A total 80 extracted mandibular premolars were used decoronated cemento-enamel junction. The roots randomly divided into groups 20 specimens each. instrumented according manufacturer’s instructions each file, canals irrigated sodium hypochlorite (NaOCl), Ethylene-diaminete-traacetic acid (EDTA) Normal saline file use, two grooves prepared on buccal lingual surfaces by disc facilitate vertical splitting a chisel. presence evaluated under Scanning Electron Microscope. RESULTS: Trunatomy remove substantially better than PTN S-one Plus. one gold significantly removes PTN. in group was lower other groups, all experimental files middle coronal thirds compared apical third. CONCLUSION: showed capacity demonstrated cleanliness at third roots.
