Contribution of dowel action to interfacial shear transfer in flat joints with unbonded posttensioned bars for precast segmental bridges

Structural Concrete, EarlyView.
Abstract Dry joints are widely used in precast segmental bridge construction because they simplify assembly and accelerate erection. Incorporating fasteners crossing flat dry joints represents an innovative configuration for this type of connection.

Identity Entanglement: Rethinking Marginality through the Intersectional, Liminal, and Antithetical

Symbolic Interaction, EarlyView.
While identity research has given sustained attention to marginality, intersectionality, and the effects of power on identity, the formal interactional dynamics through which identities are constituted remain limited. I present identity entanglement as a useful framework for better understanding and articulating the relational complexities of identity.

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.

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

Influence of Smear Layer on Depth of Demineralization and Thickness of Hybrid Layer

The Journal of Adhesion, 2013
In order to evaluate the thickness of the hybrid layer and depth of demineralization of dentin surfaces submitted to different treatments, dentin slices from human teeth were divided into two groups: one polished with 60-grit SiC paper and the other with 600-grit SiC paper.

The smear layer: a phenomenon in root canal therapy

International Endodontic Journal, 1995
SummaryWhen the root canals are instrumented during endodontic therapy, a layer of material composed of dentine, remnants of pulp tissue and odontoblastic processes, and sometimes bacteria, is always formed on the canal walls. This layer has been called the smear layer.

Evaluation of techniques for removal of smear layer [PDF]

, 2015
During mechanical and manual preparations and incision of hard dental tissues consecutive smear layer is created. The views of the scientific community for its elimination or incorporation are divided. The aim of the study was to evaluate the techniques and methods for removing the smear layer during endodontic therapy procedures. In this research will

The influence of smear layer in lateral channels filling

Clinical Oral Investigations, 2007
This 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

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 ...

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.
