Toothpick
A toothpick is a small thin stick of wood, plastic, bamboo, metal, bone or other substance with at least one and sometimes two pointed ends to insert between teeth to remove detritus, usually after a meal. Toothpicks are also used for festive occasions to hold or spear small appetizers (like cheese cubes or olives) or as a cocktail stick, and can be decorated with plastic frills or small paper umbrellas or flags. History Known in all cultures, the toothpick is the oldest instrument for dental cleaning. Hominin remains from Dmanisi, Georgia, dated to about 1.8 million years ago, bear lesions indicating the repeated use of a “toothpick”. A Neanderthal man's jawbone found in the Cova Foradà in Spain evidenced use of a toothpick to alleviate pain in his teeth caused by periodontal disease and dental wear. Toothpicks made of bronze have been found as burial objects in prehistoric graves in Northern Italy and in the East Alps. In 1986, researchers in Florida discovered the ...

Raccoon
The raccoon ( or , ''Procyon lotor''), sometimes called the North American, northern or common raccoon (also spelled racoon) to distinguish it from Procyonina, other species of raccoon, is a mammal native to North America. It is the largest of the procyonid family, having a body length of , and a body weight of . Its grayish coat mostly consists of dense underfur, which insulates it against cold weather. The animal's most distinctive features include its extremely dexterous front paws, its facial mask, and its ringed tail, which are common themes in the mythologies of the Indigenous peoples of the Americas surrounding the species. The raccoon is noted for its animal cognition, intelligence, and studies show that it can remember the solution to tasks for at least three years. It is usually nocturnal and omnivorous, eating about 40% invertebrates, 33% plants, and 27% vertebrates. The original habitats of the raccoon are deciduous and temperate broadleaf and mixed forests, mixed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dental Floss
Dental floss is a cord of thin filaments, typically made of nylon or silk, used in interdental cleaning to remove food and dental plaque from between teeth or places a toothbrush has difficulty reaching or is unable to reach. Its regular use as part of oral cleaning is intended to maintain oral health. Use of floss is recommended to prevent gingivitis and the build-up of plaque. The American Dental Association claims that up to 80% of plaque can be removed by flossing, and it may confer a particular benefit in individuals with orthodontic devices. However, empirical scientific evidence demonstrating the clinical benefit of flossing as an adjunct to routine tooth brushing alone remains limited. History Levi Spear Parmly (1790-1859), a dentist from New Orleans, is credited with inventing the first form of dental floss. In 1819, he recommended running a waxen silk thread "through the interstices of the teeth, between their necks and the arches of the gum, to dislodge that ir ...

Cova Foradà
Cova Foradà (or Cova Foradada) is an archaeological site consisting of a cave with remains of Neanderthals near Oliva, in the Province of Valencia, Spain. The most complete skeleton of a Neanderthal ever found on the Iberian peninsula was found there in 2010. One of the Neanderthals whose remains were found in the cave used a toothpick to alleviate pain in his teeth caused by periodontal disease and dental wear. Location and description The karst cave is located southeast of the village of Oliva, at from the coast of the Mediterranean, and archaeological excavations have taken place since 1977. The cave is found in a low hill, one of a group of hills called the Muntanyetes de Oliva, the last part of the Serra de Mustalla before the floodplain that ends at the coast. It has been occupied since the Middle Paleolithic, including in the Mousterian and Mesolithic periods, and in the Bronze Age. Its environment was rich and varied, with mountains on one side and lagoons on the oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interdental Cleaning
Interdental cleaning or interproximal cleaning is part of oral hygiene where the aim is to clean the areas in between the teeth, otherwise known as the proximal surfaces of teeth. This is to remove the dental plaque in areas a toothbrush cannot reach. The ultimate goal of interproximal cleaning is to prevent the development of interproximal caries and periodontal disease. The combined use of tooth brushing and mechanical and manual interdental cleaning devices has been proven to reduce the prevalence of caries and periodontal diseases. Floss Floss is one of the most commonly used interdental cleaners. It is traditionally made of waxed nylon wrapped up in a plastic box. Since dental floss is able to remove some inter-proximal plaque, frequent regular dental flossing will reduce inter-proximal caries and periodontal disease risks. Results of a high-level of evidence meta-analysis recently found that floss may not be the most effective method for interdental cleaning, contrary to c ...

Wood
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or more broadly to include the same type of tissue elsewhere, such as in the roots of trees or shrubs. In a living tree, it performs a mechanical-support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients among the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, woodchips, or fibers. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production ...

Baculum
The baculum (: bacula), also known as the penis bone, penile bone, ''os penis'', ''os genitale'', or ''os priapi'', is a bone in the penis of many placental mammals. It is not present in humans, but is present in the penises of some primates, such as the gorilla and the chimpanzee. The baculum arises from primordial cells in soft tissues of the penis, and its formation is largely influenced by androgens. The bone lies above the male urethra, urethra, and it aids sexual reproduction by maintaining stiffness during sexual penetration. The Homology (biology), homologue to the baculum in female mammals is the baubellum (''os clitoridis''), a bone in the clitoris. Etymology The word ''baculum'' means "stick" or "staff" in Latin and originates from , ''baklon'' "stick". Function The baculum is used for copulation and varies in size and shape by species. Its evolution may be influenced by sexual selection, and its characteristics are sometimes used to differentiate between simila ...

Birch
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech- oak family Fagaceae. The genus ''Betula'' contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are typically short-lived pioneer species and are widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Birch wood is used for a wide range of purposes. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara, although the wings may be obscure in some species. They differ from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
