The aim of this study was to evaluate tooth whitening and the antimicrobial effects of the ethanolic extract of the Persian nutshell “Juglans regia”. Materials and methods: The minimum inhibitory concentration (MIC) was determined using a broth microdilution assay that was conducted using a 2-fold serial dilution method, and a whitening experiment was done in vitro on extracted teeth, with a pH test being performed in 2-fold dilutions of the ethanol extract. Result. It was found that the MIC for Enterobacter and E. coli and Staphylococcus e It was found that Pseudomonas was 5 mg / ml and 2.5 mg / ml, respectively. Both dilutions were considered acidic, and the bark extract of Juglans regia also demonstrated the ability to whiten teeth. Conclusion .
