TLDR
In this article, the minimum inhibitory concentration (MIC) was determined using a broth microdilution assay which was conducted through a 2-fold serial dilution method, and a whitening experiment was done in vitro on extracted teeth, with a pH test being performed on 2fold dilutions of the ethanol extract.Abstract:
Objectives Natural folk medicines with antimicrobial effects have been under investigation during the past decades. The aim of this study was to evaluate the teeth whitening and antimicrobial effects of ethanol extract of Persian walnut "Juglans regia" barks. Materials and methods Minimum inhibitory concentration (MIC) was determined using a broth microdilution assay which was conducted through a 2-fold serial dilution method, and a whitening experiment was done in vitro on extracted teeth, with a pH test being performed on 2-fold dilutions of the ethanol extract. Result It was found that the MIC for Enterobacter and E. coli and Staphylococcus and Pseudomonas was found to be 5 mg/ml and 2.5 mg/ml, respectively. Both dilutions were found to be acidic, and the extract of Juglans regia bark also demonstrated the ability of teeth whitening. Conclusion This study supports the use of Juglans regia bark as a natural product in dentistry because of the confirmed antimicrobial ability as well as its whitening effect. Clinical Relevance. Herb extract might be incorporated within commercially available kinds of toothpaste to enhance its whitening and antimicrobial effects.read more

TL;DR: The purposes were to utilize culture-independent molecular techniques to extend the knowledge on the breadth of bacterial diversity in the healthy human oral cavity, including not-yet-cultivated bacteria species, and to determine the site and subject specificity of bacterial colonization.

TL;DR: The availability of complete genome sequences for several bacterial pathogens coupled with bioinformatics will lead to significant advances toward the identification and characterisation of all these different strategies for bacterial disease.

Modulation of host responses by oral commensal bacteria
TL;DR: A wide range of bacterial components and/or products can mediate immunomodulatory activity, raising the possibility of development of alternative strategies for therapy and health promotion using probiotics, prebiotics, or commensal-derived immunommodulatory molecules.

TL;DR: The demographic history of walnut and its routes of dispersal across Europe are reconstructed by integrating fossil pollen, cultural, and historical data with population genetics, and approximate Bayesian analysis and it is concluded that human-mediated admixture between Anatolian and Balkan walnut germplasm started in the Early Bronze Age.
