any studies have demonstrated that the use of chewing gum stimulates salivary flow, thus, enhancing the saliva remineralization potential. Fructooligosaccharides (FOS) are used in some countries as sucrose substitutes, but their cariogenic potential has not been completely elucidated yet. The aim of this study was to evaluate the effect of chewing gum containing sucrose or FOS (Meiji Seika, Jap...

BACKGROUND The effect of the fluoride in the caries prevention is strongly linked to its topical action. When the fluoride is ingested, its anticaries effect is weak and, in addition, it can cause side effects such as dental fluorosis in children. The toothbrushing with fluoride dentifrice is a suitable procedure to provide the topical fluoride, but in small children there is risk of inadverten...

in this research, during three consecutive years (2010-2012), a series of diallel crossing was performed among wild type barberry genotypes and iranian seedless barberry. setting of seed and fruit in the crossing have been studied and then seedling survival were evaluated in several cultural systems. results showed significant effects of pollen sources on setting of fruits, seed and seeded frui...

Berberis thunbergii L. (Japanese barberry) holds significant market share in the commercial ornamental horticulture industry. Japanese barberry is grown by production nurseries and used landscaping across northern half of United States. In 2009, crop was worth nearly $30.5 million annual sales States, making it one top two shrubs, roses excluded. [U.S. Department Agriculture (USDA) 2009]. Dirr ...

School-age children are frequently at high risk for the onset of biofilm-dependent conditions, including dental caries and periodontal diseases. The objective of this study was to evaluate the clinical efficacy of a dentifrice containing Eugenia uniflora Linn. (Surinam cherry) extract versus a triclosan-based comparator in treating gingivitis in children aged 10-12 years. The in vitro antibacte...

OBJECTIVE This double-blind clinical study, conducted at the University of Puerto Rico, San Juan, Puerto Rico, was designed to compare the efficacy of two commercially available dentifrices for the control of supragingival plaque and gingivitis. METHODS Qualifying adult male and female subjects from the San Juan, Puerto Rico area were randomly assigned to one of two treatment groups: 1) a com...

OBJECTIVE To determine the ability of various marketed dentifrices containing stabilized stannous fluoride (SnF2), sodium fluoride (NaF), or sodium monofluorophosphate (SMFP) to protect enamel against the earliest stages of erosive dietary acid damage using an in vitro enamel protection model. METHODS Acid-challenged, extracted human teeth were treated with a 1:3 dilution of dentifrice, rinse...

The aim of this study was to evaluate by micro-shear bond strength test, the bond strength of composite resin restoration to enamel submitted to whitening dentifrices. Forty bovine teeth were embedded in polystyrene resin and polished. The specimens were randomly divided into eight groups (n=5), according to the dentifrice (carbamide peroxide, hydrogen peroxide and conventional dentifrice) and ...

AIM Food and medicinal applications of barberry date back to 2500 years ago. This study investigates Berberis integerrima impact on lymphocytic immune responses. MATERIALS & METHODS Balb/c splenocytes were treated by 0.001-1000 μg/ml of B. integerrimaaqueous and alcoholic extracts in presence of phytohemagglutinin and lipopolysaccharide mitogens. Cell proliferation was assayed and cytokines w...

PURPOSE To assess whether a fluoride dose response could be detected with a relatively small sample size in a short duration using a novel randomized, double-blind study design. METHODS Subjects (N = 644, with approximately 215 per group) with a mean age of 10.4 years old (9-12 years old) used a placebo dentifrice, an 1100 ppm F dentifrice or a 2800 ppm F dentifrice for the first 9 months of ...
