BACKGROUND Bacteria like E. faecalis can produce intra- and extra-radicular biofilms. Theoretically, the adjustable penetration ability of lasers enables better access to root canal system. Therefore the aim of the present study was to compare the ability of photoactivated laser and 2.5% NaOCl irrigation solution to eliminate E. faecalis from the root canals by real-time PCR technique. MATERI...

Nowadays, essential oils are used in different products such as food as natural antioxidants, antibacterial and flavoring compounds (1). Essential oils are used as a replacement for chemical preservatives such as butylated hydroxytoluene (BHT) and tertiary butyl hydroquinone (TBHQ) that can threaten human health as cancer promoters (2). Nearly 3000 different essential oils are known today, and ...

the infections risk related to pathogenic germs increases at the present time considering the increased resistance which certain microbes acquire, whose usual antibiotics are ineffective to treat the infectious disease. the aim of this study was to determine antimicrobial effect of the aqueous and ethanolic extracts of lavandula stoechas l. and rosmarinus officinalis l. on listeria monocytogene...

Introduction: The Enterococcus faecalis (E. faecalis) is the one of the pathogenic bacteria that become famous and considerable in the recent years. Here we tried to do typing the E. faecalis isolates to provide advantageous information that can help us to understand epidemiological communication between the E. faecalis isolates. Materials and methods: One hundred  E. faecalis were isolated fr...

Thyme (Thymus vulgaris) belongs to the Lamiaceae family, and has been used since antiquity in traditional medicine. It is recognized by its therapeutic virtues. The ancient-Iranians were familiar with many medicinal herbs and were aware of their usefulness in treatment of various diseases. In this study Thymus vulgaris L. to evaluate the antimicrobial activity, Disc Diffusion Test with KirbyBau...

Background: The disk diffusion method for identification of yeasts species was performed based on different but distinct susceptibilities of yeasts spp. to chemicals: janus green, ethidium bromide, 2,3,5-triphenyltetrazolium chloride, brilliant green, cycloheximide and rhodamine 6G. Methods: Atotal of 568 Iranian soldiers went under study for isolation and identification of Yeast species from t...
