camellia hiemalis/dental caries

Tea (Camellia sinensis) catechins have been studied for disease prevention. These compounds undergo oxidation and produce H(2)O(2). We have previously shown that holding tea solution or chewing tea leaves generates high salivary catechin levels. Herein, we examined the generation of H(2)O(2) in the

This study compared the in vitro responses of malignant and normal cells from the human oral cavity to tea extracts and to its main polyphenolic component, (-)-epigallocatechin gallate (EGCG). The antiproliferative effects of tea polyphenolic extracts and EGCG were more pronounced towards

BACKGROUND Epigallocatechin-3-gallate (EGCG) is a flavonoid extracted from green tea that demonstrated antimicrobial activity. OBJECTIVE To evaluate the efficacy of EGCG 0.5%, 1%, and 2% concentrations as an antimicrobial solution in dentin caries-like lesions induced in a bacterial-based in vitro

We report on a naphthalimide ratiometric fluorescent probe for the real-time sensing and imaging of pathogenic bacterial glucosyltransferases, which are associated with the development of dental caries. Using a high-throughput screening method, we identified that several natural polyphenols from

This study demonstrated that streptococcus mutans could be inhibited completely after contacted with 0.1% CTP for 5 minutes. There were no drug resistance after repeat cultures in 0.025% CTP. Plaque Index and Gingival Index decreased significantly (P < 0.001) after 0.2% CTP were used to rinse and

Even though the reduction of caries-incidence in developed countries, its increasing has been observed nowadays. The use of a vaccine was object of many researches, going under modifications and evaluations during years. Wallace and McCollum showed the chance to induce experimental cavities, while

This study investigated the remineralization effect of experimental mint formulations containing bioactive agents (xylitol; green tea extract, GT; and amorphous calcium phosphate, ACP) in the progression of artificially induced root caries. Root caries lesions were induced by demineralization

The effects of green tea polyphenols, inhibitors of various biological activities of cariogenic bacteria in vitro, on caries development were examined using conventional rats. A total of 96 male rats were divided into 8 groups and the rats in the test groups were given tea polyphenols ranging from

OBJECTIVE Root caries is a common, debilitating condition particularly in the elderly population, which can lead to tooth loss. Evidence shows that green tea has cariostatic effects. Considering the gap of information on green tea varnish, this study aimed to assess the efficacy of green tea varnish

OBJECTIVE Black tea (Camellia sinensis) may have anticariogenic properties. The present study was designed to determine whether consumption of black tea influences cariogenesis in young, caries-prone rats. METHODS Eighteen-day-old Sprague-Dawley rats (n = 24; eight per group) fed a cariogenic diet

Polyphenol compound (designated Sunphenon) from leaf of Camellia sinensis have been partially purified by extraction of the boiling water with ethyl acetate. The effect of Sunphenon on cariogenic Streptococcus mutans groups (serotype c and g) was studied in both in vitro and in vivo. The summary of

Catechins and theaflavins, polyphenolic compounds derived from tea (Camellia sinensis, fam. Theaceae), have been reported to have a wide range of biological activities including prevention of tooth decay and oral cancer. The present study was undertaken to determine the usefulness of green tea

OBJECTIVE Green tea extract has been advocated as a matrix metalloproteinase (MMP) inhibitor; however, its effect on bond durability to caries-affected dentin has never been reported. Thus, the aim of this in vitro study was to evaluate the effect of two MMP inhibitors (2% chlorhexidine and 2% green

An extract of oolong tea (semifermented tea leaves of Camellia sinensis) and its chromatographically isolated polyphenolic compound was examined for in vitro inhibitory effects on glucosyltransferases (GTases) of mutans streptococci and on caries development in Sprague-Dawley rats infected with

Streptococcus mutans (S. mutans) is the main etiological bacteria present in the oral cavity that leads to dental caries. All of the S. mutans in the oral cavity form biofilms that adhere to the surfaces of teeth. Dental caries are infections facilitated by the development of biofilm. An esterified
