objectives: biomechanical preparation and irrigation with antimicrobial solutions are necessary to disinfect the root canal space. this in vitro study aimed to examine the antifungal effect of green tea extract on candida albicans biofilm formed on tooth substrate. materials and methods: minimum fungicidal concentration (mfc) and minimum inhibitory concentration at which 90% of the isolates wer...

objectives: the aim of this study was to assess the efficacy of aloe vera and green tea mouthwash for reducing pain after periodontal pocket reduction surgery. methods: this randomized, split-mouth, double-blind, cross-over clinical trial was carried out on 45 patients between 25 and 50 years of age requiring pocket reduction surgery. patients underwent bilateral surgeries in two sessions. afte...

results the mean of the inhibition zone diameter around the discs of green tea extract in all concentrations was significantly less than 1% sodium hypochlorite (p < 0.001). the antimicrobial effect increased in higher concentrations of extracts of green tea (p < 0.001). conclusions although the antimicrobial effect increases in higher concentrations of extracts of green tea, 1% sodium hypochlor...

Background: Cadmium is a potential pollutant of the environment. It manifests cyto-toxic effects in different organs in animals. In the testis, changes due to disruption of the blood-testis barrier and oxidative stress have been noted. Therefore, the present study was carried out to investigate the potential protective effects of vitamin E and green tea extract in combination against cadmium (C...

polyamide 6 has been widely used in food packaging applications and also green tea contains amounts of antioxidant compounds. the aim of this study was investigation of green tea effects on properties of polyamide packaging polymer. polyamide 6 was dissolved in methanol which was saturated with calcium chloride. the active packaging film was produced by incorporation of methanol green tea extra...

Green tea has been shown to be a potent chemopreventive agent against lung tumorigenesis in animal models. Previously, we found that treatment of A/J mice with either green tea (0.6% in water) or a defined green tea catechin extract (polyphenon E; 2.0 g/kg in diet) inhibited lung tumor tumorigenesis. Here, we described expression profiling of lung tissues derived from these studies to determine...

introduction: vaginitis is an inflammatory and infectious disease in human host that involved vaginal mucosa. increase of resistance to various antibacterial agent has been very significant in three or four recent decades and this important subject reveals the use of new and natural sources such as plants with medical and antimicrobial property for eradication of these infections. therefore, th...

Recent studies suggested that green tea has the potential to protect against diet-induced obesity. The presence of caffeine within green tea has caused limitations. Cocoa tea (Camellia ptilophylla) is a naturally decaffeinated tea plant. To determine whether cocoa tea supplementation results in an improvement in high-fat diet-induced obesity, hyperlipidemia and hepatic steatosis, and whether su...

The effect of green tea extracts on the sporulation of oocysts of 3 species of Eimeria was investigated. The unsporulated oocysts were exposed to 0%, 5% and 10% of green tea extracts (1 and 2% strengths, w/v). A new sporulation inhibition bioassay was designed to evaluate the anticocccidial activity of the tea extracts. The results showed for the first time that water-soluble extracts from gree...
