statement of problem: dental caries is one of the most common chronic diseases in children. the balance between demineralization and remineralization of the decayed teeth depends on the calcium and phosphate content of the tooth surface. therefore, if a product such as casein phospho peptides - amorphous calcium phosphate (cpp- acp) which can significantly increase the availability of calcium a...

conclusion safire reconstruction provided better coronary image quality and displayed the number, morphology, and surrounding lumen of calcium plaques more accurately than traditional fbp reconstruction, with safire3 achieving the best results. results the subjective ratings of image quality using safire1–safire5 reconstructions were significantly higher than those using fbp, with safire3 achie...

statement of problem: the casein phospho peptide-amorphous calcium phosphate with or without fluoride (cpp-acpf and cpp-acp respectively) are of considerably new materials which are highly recommended for prevention of dental caries. however, there is a shortage in literature on how they affect the ion concentration of saliva or dental plaque. objectives: the aim of this study was to evaluate t...

the present work compared the clinical efficacy of ropically applied vitamin d3 (cholecalciferol), i a, 25 dihydroxy vitamin d3 (cakitriol) with calcipotriol (dovonex} in the treatment of plaque psoriasis. a randomized, double - blind, left - right, vehicle controlled study to assess the therapeutic efficacy and safety of mice daily application of 1 pg/g and 5 fj.g1g chalecakiferol. 1 pglg calc...

The activity of calcium in plaque fluid is needed to calculate the saturation level of that fluid relative to the tooth mineral. One method to determine the calcium activity in very small plaque fluid samples is by micro ion-selective electrode (ISE). Two commercially available calcium ionophores, a neutral-carrier and a charged-carrier, were evaluated in micro ISEs and compared to a commercial...

Idiopathic calcium oxalate (CaOx) stone-formers (ICSFs) differ from patients who make idiopathic calcium phosphate (CaP) stones (IPSFs). ICSFs, but not IPSFs, form their stones as overgrowths on interstitial apatite plaque; the amount of plaque covering papillary surface is positively correlated with urine calcium excretion and inversely with urine volume. The amount of plaque predicts the numb...

Renal stone incidence has progressively increased in industrialized countries, but the implication of Randall plaque in this epidemic remains unknown. Our objectives were to determine whether the prevalence of Randall plaque-related stones increased during the past decades after having analyzed 30,149 intact stones containing mainly calcium oxalate since 1989 (cross-sectional study), and to ide...

BACKGROUND Spotty superficial calcium deposits have been implicated in plaque vulnerability based on previous intravascular imaging studies. Biomechanical models suggest that microcalcifications between 5 and 65 µm in diameter can intensify fibrous cap stress, promoting plaque rupture. However, the 100- to 200-µm resolution of intravascular ultrasound limits its ability to discriminate single c...

BACKGROUND Overgrowth of calcium oxalate on Randall's plaque is a mechanism of stone formation among idiopathic calcium oxalate stone-formers (ICSFs). It is less clear how stones form when there is little or no plaque. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Participants were a consecutive cohort of ICSFs who underwent percutaneous nephroscopic papillary mapping in the kidney or kidneys...

objective: although the most useful method to reduce mechanical dental plaque is brushing and flossing, but due to the lack of adequate effectiveness achieved by these methods, the use of other methods such as replacing sweeteners, including xylitol and sorbitol with sucrose in products such as chewing gums have come into the focus of attention. this research was done aimed at examine the effec...
