The antibacterial evaluation of dandelion extracts as root canal irrigating solutions (A comparative study)
...Show More Authors

Background: Irrigation has a central role in endodontic treatment. Several irrigating solutions have the antimicrobial activity and actively kill bacteria and yeasts when introduced in direct contact with the microorganisms. The purpose of this study was to evaluate the antimicrobial effectiveness of Dandelion (Taraxacum officinale) root and leaf extracts as possible irrigant solutions, used during endodontic treatments, and both were compared to Sodium hypochlorite, Propolis and Ethyl alcohol. Materials and Method: Forty seven human extracted single rooted teeth were selected. The teeth were decoronated using a diamond disk to have a length of 15 mm ±1 mm and they were instrumented using the hybrid technique. All roots were sterilized by an autoclave, five roots without bacterial inoculation served as the negative controls, the rest were inoculated with Enterococcus faecalis, then five roots were selected randomly as the positive controls, then the remaining 37 roots were divided into five groups of 8 samples each except group V with 5 roots. Group I: irrigated with Propolis extract. Group II: irrigated with Dandelion leaf extract. Group III: irrigated with Dandelion root extract. Group IV: irrigated with Sodium hypochlorite. Group V: irrigated with Ethyl alcohol. Bacterial swabs were taken from each root and cultured. Bacterial growths were calculated by counting the number of colonies appeared on the cultures. Results: the results were statistically analyzed; within the limitation of this in vitro study, the Dandelion leaves extract and Dandelion root extract proved to have some antimicrobial properties. Sodium hypochlorite has the best antimicrobial effect, followed by Propolis, Dandelion root, Ethyl alcohol then Dandelion leaf. Conclusion: Dandelion root and leaf extracts are possible irrigant solutions that can be used successfully during endodontic treatments, to aid disinfection of the root canal system.

Synthesis, Characterization and Antibacterial Activities of Mixed Ligand Complexes of Symmetrical Schiff Base and 8-Hydroxyquinoline with Zn(II), Cd(II) and Hg(II)
...Show More Authors

The current work reports a new Schiff base [N1-benzylidenebenezene-1,2-diamine(L) = C20H16N2] has been synthesized from benzaldehyde (C6H5CHO) and O- aminoaniline (O-C6H4(NH2)2. Metal mixed ligand complexes of the Schiff base were prepared from chloride salts of Zn(II), Cd(II) and Hg(II) in ethanol and 8-hydroxyquinoline(8HQ)(C9H7NO) containing sodium hydroxide. All the complexes were characterized on the basis of their; FT-IR and U.V spectra, melting point, molar conductance, and determination of the percentage of the metal in the complexes by flame (AAS). In the all complexes, (8HQ) behaves as a bidentate ligand as primary ligand through –-OH phenolic group and –N groups of pyridine group. Also, the prepared ligand (L) was bidentate i
