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 removal using passive ultrasonic irrigation and different concentrations of sodium hypochlorite.

Journal of Endodontics, 2020
INTRODUCTION The present study evaluated the effect of passive ultrasonic activation (PUI) of EDTA solution followed by conventional irrigation with two concentrations of sodium hypochlorite (NaOCl) on smear layer removal.

Effect of smear layer deproteinization with chemo-mechanical caries removal agents on sealing performances of self-etch adhesives.

E -journal of dentistry, 2020
OBJECTIVES To evaluate the sealing performance of self-etch adhesives (SEA) after smear layer deproteinization with chemo-mechanical caries removal agents (CRA) to enamel and dentin cavity walls in comparison with 6% NaOCl smear layer deproteinizing ...

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 ...

Can irrigant agitation lead to the formation of a smear layer?

Journal of Endodontics, 2020
INTRODUCTION This study aimed at assessing whether ultrasonic activation (UA), EasyClean (EC) or EDDY (ED) systems, used to promote agitation of the irrigating solutions during the final irrigation step, can lead to smear layer formation in the apical ...

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.
