OBJECTIVE
To compare and explore the dose-response of phytate-containing 1150 ppm fluoride toothpastes on model caries lesions and to determine the impact of zinc ions.
METHODS
This was a single-centre, randomised, blinded (examiner/laboratory analyst), six-treatment, four-period crossover, in situ
Previous studies have shown that enamel permselectivity can influence fluid composition within caries lesions during de- and remineralization. The permselectivity of human enamel, cementum, and dentin sections was examined, in a microwell model, by measurement of the membrane potential developed by
Agriculture P management practices elevate the level of inorganic phosphates in soil that results in phosphorous (P) seepage into water-bodies. This is one of the key factors that have accelerated the menace of eutrophication. Phytic acid (phytate)-P-rich plant metabolite is infamous for its
Purpose: Recently, non-exposure simple suturing endoscopic full-thickness resection (NESS-EFTR) was developed to prevent tumor exposure to the peritoneal cavity. This study aimed to evaluate the feasibility of NESS-EFTR with sentinel
Injection of myo-[2-(3)H]inositol or scyllo-[R-(3)H]inositol into the peduncular cavity of wheat stalks about 2 to 4 weeks postanthesis led to rapid translocation into the spike and accumulation of label in developing kernels, especially the bran fraction. With myo-[2-(3)H]inositol, about 50 to 60%
OBJECTIVE
Extracorporeal shock wave lithotripsy (ESWL) is one of the most commonly used procedures for removal of renal calculi from the upper urinary tract, but complete expulsion of the fragments generated is not always achieved. This can lead to new lithiasic episodes, and it is considered that
An experimental model to reproduce, to some extent, the conditions prevailing during the formation of the so-called sedimentary urinary stones, was developed. The results obtained demonstrated that in the absence of organic matter no calcium phosphate crystals were deposited in cavities with scarce
The caries-preventive effect of phosphate additives in cariogenic diets fed to white rats has been further demonstrated. Diammonium phosphate, beta-glycerol phosphate, and sodium phytate again were shown to be caries-inhibiting, as was a 1,6-fructose diphosphate. The caries-inhibiting action of
Historical data, epidemiological surveys, laboratory and animal experiments, clinical studies and observations in ordinary dental practice all illustrate that starchy fibrous foods have a low cariogenic potential. The recommended substitution of sucrose in Western diets by starchy foods would lead
Saliva is an important factor in the neutralization of the acidity of the refluxed material that comes from the stomach to the esophagus. The impairment of saliva transit from oral cavity to distal esophagus may be one of the causes of esophagitis and symptoms in gastroesophageal reflux disease
Endometrial cancer is the most common gynecologic cancer, and lymph node metastasis is one of the most important prognostic factors. Increasing evidence shows that sentinel lymph node (SLN) mapping is an effective alternative to comprehensive lymphadenectomy. Single photon emission CT Absorptiometric, histomorphometric, and chemical analyses of bones from growing rats fed diets with low (0.2%, w/w), marginal (0.4%, w/w), or adequate (0.8%, w/w) calcium (Ca) content with or without phytate were compared. Phytate was added to each diet in a molar ratio of 19:1 to calcium. Male
We assessd the feasibility and problems associated with sentinel lymph node (SLN) study in 13 cases of oral and pharyngeal squamous cell carcinoma (SCC) that were neck-node-negative clinically. The primary sites were the tongue (n = 10), other sites in the oral cavity (n = 2), and the mesopharynx (n
