Effect of Removal of the Smear Layer on Apical Microleakage
Journal of Endodontics, 2001It has been shown previously that the smear layer created during instrumentation of the root canal promotes apical microleakage. The purpose of the present study was to investigate the effect of removal of the smear layer on apical microleakage, using the fluid filtration method. Thirty-six single-rooted human premolar teeth were used. Six of the teeth

Effect of Ultrasonic Activation of Irrigants on Smear Layer Removal
Journal of Endodontics, 2015The objective of this study was to evaluate the efficacy of passive ultrasonic irrigation (PUI) with 17% EDTA and 1% NaOCl solutions on smear layer removal.Root canal preparations of 32 human teeth were performed with the ProTaper system. Next, they were longitudinally fractured to permit quantitation of smear layer creation from the cervical, middle ...

Dentin permeability: Effects of smear layer removal
The Journal of Prosthetic Dentistry, 1981The results of this study permit the following conclusions: 1. The use of dilute (6%) citric acid for very short time intervals permits sequential removal of the smear layer on human dentin. 2. Acid-etching for as little as 5 seconds removes much of the smear layer and exposes the orifices of dentinal tubules. 3.

Smear layer removal effects on apical leakage
Journal of Endodontics, 1986Reliable techniques of smear layer formation and removal were developed. Thirty-four teeth with smear layers and 34 teeth without smear layers were tested in vitro to evaluate the effects on apical leakage. These teeth were obturated using Hydron or chloroform-softened gutta-percha master cones with sealer and lateral condensation. Apical leakage was

The Effect of EDTA with and without Ultrasonics on Removal of the Smear Layer
Journal of Endodontics, 2009This study evaluated in vitro effectiveness of 17% EDTA with and without ultrasonics on smear layer removal. One hundred and five extracted premolars randomly divided into seven groups were instrumented with different final irrigating protocols: group A (Sal3US), saline for 3 minutes with ultrasonics; groups B (Na3) and C (Na3US), 1% sodium ...

Removal of intracanal smear layer by doxycycline: SEM analysis
Australian Endodontic Journal, 2010AbstractThe aim of this study was to verify the efficacy of doxycycline used alone or in association with sodium hypochlorite on smear layer removal. The canals of extracted human teeth were instrumented using a stepback technique. At the end of preparation, they were irrigated with doxycycline (Group 1), ethylenediaminetetraacetic acid + sodium ...

Atomic Force Microscopy of Removal of Dentin Smear Layers
Microscopy and Microanalysis, 2007The regular periodontal practice of scaling and root planing produces a smear layer on the root surface that is detrimental to the readhesion of tissues during subsequent regeneration therapy. Although it has been demonstrated that gels containing the chelating agent ethylenediaminetetraacetic acid (EDTA) can assist in the removal of this contaminating

The effect of smear layer removal on marginal contraction gaps
Journal of Oral Rehabilitation, 1994SummaryThe presence of the smear layer prevents direct contact between dentine and a dentine adhesive. The use of agents to remove the smear layer theoretically should improve the bonding of composite resins to dentine. This study examined the effect of smear layer removal on the effectiveness of a dentine bonding agent in reducing marginal contraction

Smear layer removal with different concentrations of EDTA-ethylenediamine mixtures
Journal of Endodontics, 1993The purpose of this study was to observe the effectiveness of EDTA and ethylenediamine mixtures in removing the smear layer from prepared root canal walls following instrumentation. Thirty-five freshly extracted, single-rooted maxillary anterior teeth were used.
