    Pyria, or periodontal disease, is a progressive gum disease characterized by inflammation resulting from the toxins found in plaque. It leads to bleeding of the gums. If allowed to progress, Pyria begins to destroy underlying tissue, which may eventually lead to tooth loss or infection in other areas of the body as the bacteria travels by bloodstream.

    Habitat is generally defined as the natural environment of an organism, the place in which it is natural for it to live and grow. It is the natural environment in which an organism lives, or the physical environment that surrounds a species population. It is similar in meaning to ‘biotope’, an area of uniform environmental conditions associated with a particular community of plants and animals.

    Glycogen, the principal storage form of glucose in animal cells, sometimes called “animal starch” for its resemblance with starch found in plants. It t is stored in liver and muscle cells and can be converted to glucose if needed. In the liver this conversion is regulated by the hormone glucagon.

    Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, phospholipids, and others. They encompass molecules such as fatty acids and their derivatives (including tri-, di-, monoglycerides, and phospholipids), as well as other sterolcontaining metabolites such as cholesterol.
