Analysis of acid‐treated dentin smear debris and smear layers using confocal Raman microspectroscopy
Journal of Biomedical Materials Research, 2002AbstractSmear layers are generally present on any dentin surface prepared with cutting instruments and are often the only available substrate for bonding. It is commonly reported that acid removes these layers, but to date there has been no chemical evidence to support this observation.

Smear Layer Outcome on Healing
2015Abstract : 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.

Removal of intracanal smear layer by doxycycline: SEM analysis
Australian Endodontic Journal, 2010AbstractThe aim of this study was to verify the efficacy of doxycycline used alone or in association with sodium hypochlorite on smear layer removal. The canals of extracted human teeth were instrumented using a stepback technique. At the end of preparation, they were irrigated with doxycycline (Group 1), ethylenediaminetetraacetic acid + sodium ...

The influence of smear layer in lateral channels filling
Clinical Oral Investigations, 2007This 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

Atomic Force Microscopy of Removal of Dentin Smear Layers
Microscopy and Microanalysis, 2007The regular periodontal practice of scaling and root planing produces a smear layer on the root surface that is detrimental to the readhesion of tissues during subsequent regeneration therapy. Although it has been demonstrated that gels containing the chelating agent ethylenediaminetetraacetic acid (EDTA) can assist in the removal of this contaminating

Smear layer removal with chelating agents after cavity preparation
The Journal of Prosthetic Dentistry, 1981n 1Jb.d e ns eposits on cavity walls in the form of a smear layer commonly occurs with cavity preparation. Smear layers have been analyzed with an electron microprobe and found to consist of organic and inorganic materials with particles varying in size from approximately 1 to 15 pm.’ The major organic component is believed to consist of heat ...

Smear layer and surface state affect dentin fluoride uptake
Archives of Oral Biology, 2007Polishing 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, 1995SummaryWhen 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, 1992SEM 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
