Effect of disinfectant solutions on gutta‐percha and resilon cones

Microscopy Research and Technique, 2012
AbstractThe aim of this study was to evaluate the effects of the 5.25% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX), and MTAD solutions on the surface of gutta‐percha and Resilon cones by using atomic force microscopy (AFM). Accessory cones were washed and dried.

Efficacy of chemical sterilization and storage conditions of gutta-percha cones

International Endodontic Journal, 2001
AbstractAimThe objective of the present study was to assess the efficacy of 2.5% sodium hypochlorite and 2.2% glutaraldehyde (‘Cidex’) as sterilizing agents for gutta‐percha cones. The efficacy of storage of gutta‐percha cones in the presence or absence of paraformaldehyde was also evaluated.MethodologyGutta‐percha cones artificially contaminated with ...

Surface modification of gutta-percha cones by non-thermal plasma

Materials Science and Engineering C, 2016
This study was designed to evaluate the effects of Oxygen and Argon plasma on gutta-percha surfaces. A total of 185 flat smooth gutta-percha surfaces were used. Samples were divided into groups: control: no plasma treatment; Oxygen: treatment with Oxygen plasma for 1min; Argon: treatment with Argon plasma for 1min.

Variability Of Master Gutta‐Percha Cones

Australian Endodontic Journal, 2002
AbstractThe common technique to hermetically fill prepared root canals involves the use of “standardised” guttapercha cones that are selected to fit the apical portion of the prepared canal space. These guttapercha cones are manufactured to conform to a standard size and taper which should correspond to the size and taper of standard root canal ...

Glutaraldehyde decontamination of gutta-percha cones

Journal of Endodontics, 1983
Two liquid glutaraldehyde preparations (Cidex 7 and Sporicidin) and a 5.25% aqueous sodium hypochlorite solution were compared for effectiveness in sterilizing gutta-percha cones artificially contaminated with Bacillus subtilis spores. Microbial assays showed that, when the cones were immersed in the solutions, sodium hypochlorite sterilized after 1 ...

Interaction Between Sealers and Gutta-percha Cones

Journal of Endodontics, 2003
Clinical observations seem to indicate that some gutta-percha cones are softened by contact with sealers. The purpose of the study was to verify whether an interaction existed between some sealers and different brands of gutta-percha cones. Because previous studies have indicated that the differences between brands of gutta-percha are magnified by heat,

Rapid sterilization of gutta-percha cones with glutaraldehyde

Journal of Endodontics, 1998
Five commercially available liquid glutaraldehyde preparations (Glutaron II, Cidex 28, Glutalabor, Banicide, and Anti-G-Plus) were compared for effectiveness in sterilizing gutta-percha cones artificially contaminated with Bacillus subtilis ATCC 6633 spores.

Effectiveness of disinfecting substances of gutta-percha cones

Arquivos em Odontologia, 2022
Aim: To demonstrate the effectiveness of disinfecting substances with 2% and 5% Sodium Hypochlorite and 2% Chlorhexidine Gluconate at each of the pre-established times of 0:15 and 0:30 seconds, and 1, 2, 5, and 10 minutes. Methods: This study selected 96 gutta-percha cones that were contaminated with Enterococcus Faecalis, dried and treated with the ...

Disinfection of gutta-percha cones with chlorhexidine and sodium hypochlorite

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2005
To evaluate the effectiveness of chlorhexidine (CHX) or sodium hypochlorite (NaOCl) in disinfecting gutta-percha cones, to verify contamination of gutta-percha cones in their boxes, and to identify microorganisms after intentional contamination by handling cones.Gutta-percha cones contaminated in vitro with several microorganisms were left in contact ...

Rejuvenation of brittle gutta-percha cones—A universal technique?

Journal of Endodontics, 1987
Aged gutta-percha filling cones become brittle and unsuitable for use. Based on a study of the physical properties of the material, a technique was published for reducing their fragility, thus “rejuvenating” them. Replication of this study with seven different cone brands indicated that the technique was successful with only two of the tested brands. A
