What is attrition abrasion and erosion?
Abstract. Tooth wear is the result of three processes: abrasion (wear produced by interaction between teeth and other materials), attrition (wear through tooth-tooth contact) and erosion (dissolution of hard tissue by acidic substances).
What is attrition abrasion?
Attrition refers to tooth against tooth friction- like grinding. Erosion is chemical wear on our teeth from either the acids in our diet, or stomach acid. Abrasion is wear from a foreign element against tooth- often times toothbrushes and toothpaste.
Is abrasion same as attrition?
Abrasion occurs as a result of two surfaces rubbing against each other resulting in the wearing down of one or both of the surfaces. However, attrition refers to the breaking off of particles (erosion) which occurs as a result of objects hitting against each other.
What causes attrition of teeth?
The most common cause of dental attrition is bruxism, the grinding and clenching of the teeth that occurs during sleep, usually due to muscle hypertonicity or tension. Bruxism can lead to other health problems, such as sleep apnea and temporomandibular joint disorders (TMJ) within your jaw.
What is the process of attrition?
Definition: Attrition is an erosional process. Rocks and pebbles are carried in the flow of a river. They repeatedly knock into each other, which causes the rocks to erode or to break. As the rocks continue to collide, they erode more and more, getting smaller and smaller until they are only sediment. Attrition.
What is attrition and abrasion in dentistry?
Dental attrition is caused by tooth to tooth contact forming acquired wear facets upon pristine enamel, whereas abrasion is caused by food and foreign body contact (e.g., tooth brushing) that may obliterate attrition wear patterns.
What is abrasion of teeth?
What is Tooth Abrasion? Tooth abrasion is where your teeth start to lose enamel due to some sort of outside mechanical action; in other words, your teeth are physically worn down by an external force.
Is erosion an attrition?
Attrition is a type of erosion that occurs when bed load erodes. It is characterized by wearing of land as well as the removal of dune sediments, rocks and other particles by the action of tidal currents, wave currents, high winds and other factors.
What is a attrition in geography?
Definition: Attrition is an erosional process. Rocks and pebbles are carried in the flow of a river. They repeatedly knock into each other, which causes the rocks to erode or to break. As the rocks continue to collide, they erode more and more, getting smaller and smaller until they are only sediment.
What is called a abrasion?
Medical Definition of abrasion 1 : wearing, grinding, or rubbing away by friction. 2a : the rubbing or scraping of the surface layer of cells or tissue from an area of the skin or mucous membrane also : a place so abraded. b : the mechanical wearing away of the tooth surfaces by chewing.
What is abrasion in dentistry?
Tooth abrasion is where your teeth start to lose enamel due to some sort of outside mechanical action; in other words, your teeth are physically worn down by an external force.
How is dental attrition treated?
In cases where the occlusion is severely altered by attrition, the only treatment choice may be a reconstruction with crowns and bridges. In the case of anterior wear, the loss of enamel at the incisal edge can lead to dentin exposure and the continuing loss of tooth structure due to slurry wear.
How do you explain attrition?
The term attrition refers to a gradual but deliberate reduction in staff numbers that occurs as employees retire or resign and are not replaced. It is commonly used to describe downsizing in a firm’s employee pool by human resources (HR) professionals.
What is the difference between attrition and erosion?
is that erosion is (uncountable) the result of having been being worn away or eroded, as by a glacier on rock or the sea on a cliff face while attrition is wearing or grinding down by friction. (uncountable) The result of having been being worn away or eroded, as by a glacier on rock or the sea on a cliff face.
What is the difference between attrition and abrasion?
What is Abrasion – Definition,Characteristics
How do you describe abrasion and attrition?
Abrasion is the type of wearing down which occurs as a result of material rubbing or abrading against each other. Attrition occurs when hard objects hit against each other and is eroded as a result. Abrasion causes surface level destruction whereas attrition causes destruction on a deeper level.
What is the difference between erosion and abrasion?
is that erosion is { {context|medicine|lang=en}} a shallow ulceration or lesion, usually involving skin or epithelial tissue while abrasion is { {context|medicine|lang=en}} a superficial wound caused by scraping; an area of skin where the cells on the surface have been scraped or worn away { {defdate|first attested in the mid 20 th century}}.
