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

Abstract

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

Effect of ultrasonic and Er,Cr:YSGG laser-activated irrigation protocol on dual-species root canal biofilm removal: An in vitro study

“…As reported in a study by Waleed et al ., TruNatomy files displayed superior smear layer removal and cleaning capacity than other tested file systems including Protaper Next, Wave One Gold, and S-One Plus. [ 15 ]…”

Comparative Evaluation of Debris Extrusion, Remaining Dentin Thickness and Fracture Resistance of Endodontically Treated Teeth Using Rotary and Reciprocating Endodontic File Systems: An In Vitro Study

“…However, the TruNatomy file system demonstrated less debris extrusion in comparison to the WaveOne Gold file. In a study by Waleed et al, TruNatomy outperformed all other experimental groups in terms of cleaning ability, and exhibited improved cleanliness at the coronal and middle third of the roots [ 20 ].…”
