In dermatology, an abrasion is a wound caused by superficial damage to the skin, no deeper than the epidermis. It is less severe than a laceration, and bleeding, if present, is minimal. Mild abrasions, also known as grazes or scrapes, do not scar or bleed, but deep abrasions may lead to the formation of scar tissue. A more traumatic abrasion that removes all layers of skin is called an avulsion.
Abrasion injuries most commonly occur when exposed skin comes into moving contact with a rough surface, causing a grinding or rubbing away of the upper layers of the epidermis.
Abrasion is the loss of tooth structure by mechanical forces from a foreign element. If this force begins at the cementoenamel junction, then progression of tooth loss can be rapid since enamel is very thin in this region of the tooth. Once past the enamel, abrasion quickly destroys the softer dentin and cementum structures.
Possible sources of this wearing of tooth are toothbrushes, toothpicks, floss, and any dental appliance frequently set in and removed from the mouth. The appearance is commonly described as V-shaped when caused by excessive pressure during tooth brushing. Abrasion is seen at a cervical necks of the teeth, as a deep ridge on the buccal or labial surfaces. The surface is shiny rather than carious, and sometimes the ridge is deep enough to see the pulp chamber within the tooth itself.
The teeth most commonly affected are premolars and canines.
Abrasion may refer to:
- Abrasion (medical), a wound consisting of superficial damage to the skin
- Abrasion (dental), the loss of tooth structure by mechanical forces from a foreign element
- Abrasion (geology), mechanical scraping of a surface by friction between moving particles
- Abrasion (mechanical), The effect of an abrasive: scratches, removal of surface, etc.
- Abrasion coast, a coastline that is characterised by the removal (abrasion) of material, typically resulting in sea cliffs
Abrasion is the mechanical scraping of a rock surface by friction between rocks and moving particles during their transport by wind, glacier, waves, gravity, running water or erosion. After friction, the moving particles dislodge loose and weak debris from the side of the rock.
The intensity of abrasion depends on the hardness, concentration, velocity and mass of the moving particles.
Abrasion is the process of scuffing, scratching, wearing down, marring, or rubbing away. It can be intentionally imposed in a controlled process using an abrasive. Abrasion can be an undesirable effect of exposure to normal use or exposure to the elements.
