Effect of smear layer removal on the diffusion permeability of human roots
Journal of Endodontics, 1994Ten human maxillary incisors, extracted because of periodontal disease or nonrestorable caries, were obtained and instrumented to a size #70 K-Flex file at the working length using a standard stepback technique. Tritiated water (3H2O) was placed in the root canals and allowed to diffuse to the external surface of the roots until it reached a constant ...

Effect of smear layer removal on bleaching of human teeth in vitro
Journal of Endodontics, 1998The purpose of this study was to evaluate objectively in vitro the effectiveness of bleaching artificially discolored teeth with or without the smear layer present using sodium perborate mixed with sterile water or 35% hydrogen peroxide (H2O2). Seventy fully developed maxillary anterior teeth were artificially stained with human hemoglobin and ...

Smear layer removal with chelating agents after cavity preparation
The Journal of Prosthetic Dentistry, 1981n 1Jb.d e ns eposits on cavity walls in the form of a smear layer commonly occurs with cavity preparation. Smear layers have been analyzed with an electron microprobe and found to consist of organic and inorganic materials with particles varying in size from approximately 1 to 15 pm.’ The major organic component is believed to consist of heat ...

Effect of EDTA With and Without Surfactants or Ultrasonics on Removal of Smear Layer
Journal of Endodontics, 2007This study compared the in vitro efficacy of Smear Clear (Sybron Endo, CA), a 17% ethylenediaminetetraacetic acid (EDTA) solution with surfactants, to 17% EDTA, with and without the use of ultrasonics, in removal of the smear layer. Seventy-five extracted teeth, randomly distributed into 5 test groups, were prepared by using ProFile rotary instruments (

Dentin surface treatments for the removal of the smear layer: an SEM study
The Journal of the American Dental Association, 1987Previous studies have shown that the bond strength of glass ionomer to dentin can be increased by the removal of the smear layer. Seven materials readily available were evaluated for smear layer removal. Clinical conditions were simulated as closely as possible.

Assessment of smear layer removal protocols in curved root canals
Australian Endodontic Journal, 2013AbstractThis study sought to assess if the final rinse protocol interferes with the smear layer removal in the apical area of curved canals. Sixty‐four extracted human mandibular molars with curved mesial roots were instrumented with rotary files and divided into six experimental groups for final rinse: 1EDTA (syringe irrigation with 1 mL of 17 ...

Comparison of the Efficacy of Three Chelating Agents in Smear Layer Removal
Journal of Endodontics, 2008The purpose of this study was to compare the efficacy of SmearClear (Sybron Endo, Orange, CA), 17% EDTA, and 10% citric acid in smear layer removal. Forty-eight extracted single-rooted human teeth were randomly divided into 4 groups (n = 12) and instrumented using Mtwo nickel-titanium rotary instruments.

Influence of Root Canal Tapering on Smear Layer Removal.
The New York state dental journal, 2016The purpose of the study presented here was to compare the influence of root canal taper on the efficacy of irrigants and chelating agents in smear layer removal. Eighty mesial roots of molar teeth were selected and prepared with rotary instruments. In group A, file 30/0.02 and in group B, file 30/0.4 were placed at working length and the smear layer ...

Mechanical removal of the smear layer.
Asian journal of aesthetic dentistry, 1997The purpose of this study was to selectively remove the smear layer from dentine without altering the underlying tissue. Two groups of test samples were established. The first group consisted of flat dentine surfaces exposed transversely in the mid-coronal plane using a diamond blade.
