Removal of Surgical Smear Layer

Journal of Endodontics, 2011
During apicoectomy and retrograde cavity preparation, a smear layer, which contains microorganisms and necrotic pulpal tissues, is formed on the dentinal surfaces cut by the instruments. Bacteria can survive and proliferate inside or below the smear layer.

The Smear Layer in Endodontics

Dental Clinics of North America, 1990
With the cascade of new restorative products being unveiled almost monthly, dentists incorporating endodontics into their practices must be able to evaluate the potential of these products for successful integration into their procedures. This evaluation should be based on a knowledge of how the new products relate to the smear layer formed along the ...

Smear Layer Removal by EGTA

Journal of Endodontics, 2000
The purpose of this study was to compare the effects of ethylene glycol-bis (beta-aminoethyl ether)-N,N,N', N'-tetraacetic acid (EGTA) and EDTA on removal of the smear layer by using scanning electron microscopy. Fifteen single-rooted teeth were instrumented to size 60. Three teeth served as the control group, and the remaining teeth were assigned into

Irrigation: beyond the smear layer

Endodontic Topics, 2012
Traditionally, much of the attention placed on irrigation in endodontics has focused on smear layer removal. While the smear layer continues to be a relevant topic, other areas related to irrigation and irrigants have emerged that also require a more in‐depth analysis and understanding.

Smear layer instability caused by hemostatic agents

The Journal of Prosthetic Dentistry, 1996
The effect of hemostatic agents, other than a 15.5% Fe2(SO4)3 solution, on prepared tooth structure is unknown. The purpose of this study was to (1) compare the effect of six commonly used hemostatic solutions and two nondental astringents on the dentinal smear layer and (2) determine whether different responses caused by product and/or time could be ...

Smear layer removal effects on apical leakage

Journal of Endodontics, 1986
Reliable 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

Dentin permeability: Effects of smear layer removal

The Journal of Prosthetic Dentistry, 1981
The 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, 1996
The 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, 1991
In 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, 2007
The 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%
