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

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

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.

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.

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.

Smear Layer Outcome on Healing

2015
Abstract : The mechanical process of shaping the root canal creates a layer of organic and inorganic debris, termed the smear layer. This layer can be removed using a combination of ethylene-diamine-tetraacetic-acid (EDTA) and sodium hypochlorite (NaOCI). Smear layer removal is not the standard of care and its removal is debated.

The Effect of EDTA with and without Ultrasonics on Removal of the Smear Layer

Journal of Endodontics, 2009
This study evaluated in vitro effectiveness of 17% EDTA with and without ultrasonics on smear layer removal. One hundred and five extracted premolars randomly divided into seven groups were instrumented with different final irrigating protocols: group A (Sal3US), saline for 3 minutes with ultrasonics; groups B (Na3) and C (Na3US), 1% sodium ...

The influence of the smear layer on the sealing ability of canal obturation

International Endodontic Journal, 1987
Summary. The sealing of obturated root canals which had previously been cleaned chemically by EDTA or mechanically by ultrasound was compared using 60 single‐rooted teeth in an in vitro study. At first, the canals were manually prepared under copious irrigation with NaOCl.

[Characterizing the smear layer].

Nederlands tijdschrift voor tandheelkunde, 1991
The smear layer was first described as a debris layer which is left on all cavity walls following tooth preparation. It is composed of an outer contiguous layer of amorphous instrumentation matrix which covers all cavity walls, and a deeper zone of matrix plugs which obturate the cut tubules.
