A New Solution for the Removal of the Smear Layer

Journal of Endodontics, 2003
Various organic acids, ultrasonic instruments, and lasers have been used to remove the smear layer from the surface of instrumented root canals. The purpose of this study was to investigate the effect of a mixture of a tetracycline isomer, an acid, and a detergent (MTAD) as a final rinse on the surface of instrumented root canals. Forty-eight extracted

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 ...

Effect of Removal of the Smear Layer on Apical Microleakage

Journal of Endodontics, 2001
It 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

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.

Clinical implications of the smear layer in endodontics: A review

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2002
It has been recognized for many years that root canal instrumentation produces a smear layer that covers the surfaces of prepared canal walls. This layer contains inorganic and organic substances such as fragments of odontoblastic processes and necrotic debris.

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.

Penetrability of the smeared layer by a strain of proteus vulgaris

Journal of Endodontics, 1985
Proteus vulgaris , a highly motile, swarming organism was used to determine whether the smeared layer on the surface of cut dentin in a cavity preparation was a barrier to the passage of the test organism through the dentinal tubules. Noncarious, extracted teeth were used in the model system.

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
