A study on rats suggests that the three-dimensional structure of Sharpey's fibres intensifies the continuity between the periodontal ligament fibre and the alveolar bone (tooth socket), and acts as a buffer medium against stress. Sharpey's fibres in the primary acellular cementum are mineralized fully; those in cellular cementum and bone are ...
Nutritional status of an individual can be a crucial factor in the progression and healing of periodontal tissues. The relationship between oral health and systemic health has become an increasingly important subject. Studies have suggested that vitamins D and C in particular have a certain grade of relationship with periodontal health. However ...

These trees generally occur near river banks, so it has year round irrigation. Inga species are dependable, they produce in abundance, and they provide sustenance in bad times. A family can produce food without occupying the farmland used for food crops, because they can grow on sites neglected by agriculture.

These composites, called biocomposites, are a natural fiber in a matrix of synthetic polymers. [1] One of the first biofiber-reinforced plastics in use was a cellulose fiber in phenolics in 1908. [1] Usage includes applications where energy absorption is important, such as insulation, noise absorbing panels, or collapsable areas in automobiles ...
The alveolar bone proper is also called bundle bone because Sharpey's fibres, part of the PDL, are inserted there. Sharpey's fibres in alveolar bone proper are inserted at a right angle (just as with the cemental surface); they are fewer in number, but thicker in diameter than those found in cementum. [7]
The sugar maple is an extremely important species to the ecology of many forests in the northern United States and Canada. Pure stands are common, and it is a major component of the northern and Midwestern U.S. hardwood forests. Due to its need for cold winters, sugar maple is mostly found north of the 42nd parallel in USDA growing zones 3–5.
