Erosion protection conferred by whole human saliva, dialysed saliva, and artificial saliva

During dental erosion, tooth minerals are dissolved, leading to a softening of the surface and consequently to irreversible surface loss. Components from human saliva form a pellicle on the tooth surface, providing some protection against erosion. To assess the effect of different components and compositions of saliva on the protective potential of the pellicle against enamel erosion, we prepar...

Saliva and dental erosion

UNLABELLED Dental erosion is a multifactorial condition. The consideration of chemical, biological and behavioral factors is fundamental for its prevention and therapy. Among the biological factors, saliva is one of the most important parameters in the protection against erosive wear. OBJECTIVE This review discusses the role of salivary factors on the development of dental erosion. MATERIAL...

Source of neuraminidase in human whole saliva.

Whole saliva specimens from eight healthy human adults were examined for neuraminidase. The presence of two types of neuraminidase in four samples out of eight was demonstrated by means of polyacrylamide gel electrophoresis and sucrose density gradient centrifugation. One type is soluble and the other an insoluble, perhaps particle-bound, enzyme. The pH optima were 5.8 for the former and 5.0 to...

Comparison of Artificial Saliva Substitutes

Human saliva consists of water, glycoproteins, enzymes, antimicrobial substances and electrolytes. From biophysical point of view, saliva is a viscoelastic fluid with distinct surface activity. Commercial artificial saliva used in salivary gland disorders should resemble normal saliva in biophysical properties. In this study we evaluated the biophysical properties of saliva and existing saliva ...

Adrenal status assessed by direct radioimmunoassay of cortisol in whole saliva or parotid saliva.

We describe a direct radioimmunoassay for cortisol in 10-microliter volumes of parotid saliva or whole saliva. Binding proteins are absent from these fluids, as demonstrated by the excellent correlation between results for samples assayed directly and by a comparison procedure involving extraction with 1,2-dichloroethane. The direct assay is specific, precise, and had a lower limit of sensitivi...
