An apical leakage study in the presence and absence of the smear layer

International Endodontic Journal, 1994
SummaryThe apical seal produced by low‐temperature injection of gutta‐percha, with or without root canal sealer, in the presence or absence of the smear layer was evaluated quantitatively using an electrochemical technique. The root canals of 44 teeth were prepared with the smear layer intact following a final flush of NaOCl (group 1), while the root ...

Smear layer--materials surface.

Proceedings of the Finnish Dental Society. Suomen Hammaslaakariseuran toimituksia, 1992
SEM and TEM photomicrographs were presented of the smear layer and several dentin-adhesive interfaces. It was shown that as the wetting and penetration of the dentin adhesive increased, the shear bond strength also increased. Three categories of dentin adhesives were presented. Category one included Scotchbond, Dentin Adhesit and Gluma, with shear bond

[Smear layer on prepared dentin].

Odontostomatologike proodos, 1990
Whenever dental tissues cut with a rotary instrument, a layer of grinding debris and organic film left of their surfaces, which is described by the term "smear layer". In this paper, we present the morphology and views for the formation of the smear layer.

Mechanical removal of the smear layer.

Asian journal of aesthetic dentistry, 1997
The purpose of this study was to selectively remove the smear layer from dentine without altering the underlying tissue. Two groups of test samples were established. The first group consisted of flat dentine surfaces exposed transversely in the mid-coronal plane using a diamond blade.

[Focus on the smear layer in 1990].

Revue d'odonto-stomatologie, 1991
The smear layer is a debris-ladden layer, adhering firmly to the hard tissues of the tooth. It plays a major role in the different adhesive systems. An update of the recent knowledge on smear layer will be done in this article. When the carious lesion is removed, a microscopic debris-ladden layer forms at the level on the enamel and the dentine.

Dentin bonding agents and the smear layer.

Operative dentistry, 1992
The morphology and treatment of the smear layer are discussed. Also included are a review of dentin bonding agent classification and chemistry, and a summary of recent bond strength research results. Finally, the current status of dentin bonding agents is discussed.

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 effect of smear layer on apical microleakage].

Shanghai kou qiang yi xue = Shanghai journal of stomatology, 2015
To evaluate the effect of smear layer on apical microleakage in extracted root-filled teeth by SEM and glucose penetration model.51 straight single-rooted human teeth were randomly divided into 5 groups, instrumented and irrigated differently by groups.

Smear layer: overview of structure and function.

Proceedings of the Finnish Dental Society. Suomen Hammaslaakariseuran toimituksia, 1992
Smear layers are created on hard tissues whenever they are cut with hand or rotary instruments. This thin (1-2 microns) layer of denatured cutting debris is very tenacious and, in fact, is often the surface to which restorative materials are luted. The solubility characteristics, chemical reactivity and the structure-function relationships of this ...
