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.

Effect of smear layer on coronal microleakage
Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 1996The purpose of this study was to examine the effect of smear layer on coronal microleakage. Fifty-two single-rooted extracted human teeth with a straight root canal were chemomechanically prepared and equally divided into experimental groups A and B.

Dentine smear layer and bonding agents. Review: 1. Smear layer--nature of the smear layer.
Restorative dentistry, 1991In these two papers the nature of the smear layer will be considered first. The clinical management will then be discussed, and finally, preparation of the dentine surface to receive the new bonding systems will be considered. A subsequent paper will discuss bonding agents.

Dentine sealing provided by smear layer/smear plugs vs. adhesive resins/resin tags
European Journal of Oral Sciences, 2007The aim of this study was to evaluate the ability of five experimental resins, which ranged from hydrophobic to hydrophilic blends, to seal acid‐etched dentine saturated with water or ethanol. The experimental resins (R1, R2, R3, R4, and R5) were evaluated as neat bonding agents (100% resin) or as solutions solvated with absolute ethanol (70% resin/30%

Analysis of acid‐treated dentin smear debris and smear layers using confocal Raman microspectroscopy
Journal of Biomedical Materials Research, 2002AbstractSmear layers are generally present on any dentin surface prepared with cutting instruments and are often the only available substrate for bonding. It is commonly reported that acid removes these layers, but to date there has been no chemical evidence to support this observation.

Smear Layer Outcome on Healing
2015Abstract : The mechanical process of shaping the root canal creates a layer of organic and inorganic debris, termed the smear layer. This layer can be removed using a combination of ethylene-diamine-tetraacetic-acid (EDTA) and sodium hypochlorite (NaOCI). Smear layer removal is not the standard of care and its removal is debated.

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 ...

The influence of smear layer in lateral channels filling
Clinical Oral Investigations, 2007This in vitro study evaluated the ability of a warm gutta-percha obturation system Thermafil to fill lateral channels in presence/absence of smear layer. Forty single-rooted extracted human teeth were randomly divided into two groups for which different irrigation regimens were used: group A, 5 ml of 5% NaOCl + 2.5 ml of 3.6% H(2)O(2); group B, 5 ml of

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
