Comparison of WaveOne and ProTaper Universal Preparation Systems in the Amount of Smear Layer/Debris Production: an in-vitro SEM Study
Background and Aim: Debris and the smear layer that remain after root canal preparations may result in failure of root canal therapies. The aim of this study was to compare the smear layer formation and the amount of residual debris following the use of WaveOne and ProTaper rotary files in mesiobuccal root canals of upper first molars by scanning electron microscopy (SEM). Materials and Method...
متن کاملComparing Post-Obturation of Apical Microleakage Following the Use of Different Intracanal Chelators
Objectives: Different chelators may be used during root canal treatment, offering various advantages including lubricant effect inside the canal and smear layer removal. However, chelator residues in narrow root canals can lead to apical microleakage. The aim of this in-vitro study was to compare apical microleakage following the use of three root canal chelators via fluid filtration method in ...

متن کاملThe effect of MTAD as a final root canal irrigants on the coronal bacterial leakage of obturated root canals
The major goal of root canal treatment is to remove irritants from the root canal system, to obturate the cleaned and shaped root canals, and to prevent recontamination. Ray and Trope proposed that coronal microleakage may be a major cause of endodontic failure. Many previous studies have examined that coronal leakage might occur, even in well obturated root canals. One of the most important co...
متن کاملElectrochemical Evaluation on Apical Leakage of AH26 Sealer after Smear Layer Removal
INTRODUCTION Recently, attention has been drawn to the influence of smear layer removal on apical seal, and the relation of root canal filling material with canal wall surface in the presence and absence of the smear layer. The purpose of this study was to evaluate the influence of the smear layer removal on the apical sealing ability of AH26 sealer. MATERIALS AND METHODS Forty extracted huma...
