The effect of different irrigation protocols on smear layer removal in root canals of primary teeth: a SEM study

Acta Odontologica Scandinavica, 2019
Objective: The purpose of this study was to compare the efficacy of different irrigation protocols on smear layer removal in root canals of primary teeth by scanning electron microscopy (SEM).

Smear layer and surface state affect dentin fluoride uptake

Archives of Oral Biology, 2007
Polishing generates a smear layer (SL) on in vitro dentin samples that may influence fluoride uptake. We tested two hypotheses: SL increases fluoride uptake in superficial dentin (H1) and decreases fluoride uptake in deeper layers (H2) irrespectively of the amount of fluoride administered.Polished bovine dentin with SL present and removed by four ...

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--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 removal with different concentrations of EDTA-ethylenediamine mixtures

Journal of Endodontics, 1993
The purpose of this study was to observe the effectiveness of EDTA and ethylenediamine mixtures in removing the smear layer from prepared root canal walls following instrumentation. Thirty-five freshly extracted, single-rooted maxillary anterior teeth were used.

Qualitative analysis of smear layer treated with different etidronate concentrations: A scanning electron microscopy study

Microscopy research and technique (Print), 2019
The aim of this study was to examine the smear layer removal capacity of various etidronate treatments. Seventy‐eight roots were instrumented up to apical size X4 and randomly divided into five treatment groups and a positive control group (n = 13 ...

[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.

Scanning electron microscopy evaluation of debris and smear layer generated by two instruments used in reciprocating motion WaveOne Gold® and Reciproc Blue®.

Australian Endodontic Journal, 2019
The aim was to evaluate debris and smear layer at 1, 3 and 5 mm from the foramen of single-file systems WaveOne Gold® and Reciproc Blue®. Thirty single-rooted teeth were prepared using one of the following NiTi instruments WaveOne Gold® and Reciproc Blue®

[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.
