What is abrasion and 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 is attrition and abrasion in dentistry?

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). A further process (abfraction) might potentiate wear by abrasion and/or erosion.

What is the difference between attrition test and abrasion test?

The main difference between abrasion and attrition is that abrasion is a slow process, whereas attrition is a fast process. Moreover, abrasion occurs due to the rubbing of the surface, which causes one or both surfaces to undergo erosion. In contrast, attrition occurs due to the hitting of one surface another.

What does attrition mean in erosion?

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 abrasion process?

Abrasion is the physical process of rubbing, scouring, or scraping whereby particles of rock (usually microscopic) are eroded away by friction. Thornbury (1954, p. 47) indicates that all the four principal agencies of erosion may involve abrasion: (a) running water, (b) waves and currents, (c) wind, and (d) glaciers.

What is dental attrition?

Dental attrition is the loss of tooth structure or tissue caused by tooth-on-tooth contact. Although this type of tooth wear is considered part of the normal aging process, more rapid dental attrition may be due to larger dental problems.

What is abrasion dental?

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.

What causes abrasion?

Abrasions are most commonly caused by falling, skidding, or other types of accidents. Many abrasions occur suddenly and without warning, and may not even be noticed until after the injury. Abrasions typically occur on the extremities, exposed arms and legs, when the skin is scratched against a hard or rough surface.

What can cause dental abrasion?

Some causes of abrasion include rough, lateral tooth brushing, biting your nails, chewing on pens, pipe smoking, placing and removing denture clasps, abrasive dentifrices, and stiff toothbrushes. Toothbrush abrasion can be repaired by bonding a tooth-colored filling over the abraded area of the tooth.

How do you treat abrasion teeth?

How dentists deal with tooth abrasion. Your dentist can repair some of the damage caused by abrasion using fillings. The dentist can apply the fillings to the grooves that form where your gum and tooth meet. The filling protects the area and keeps it free of bacteria and food particles.

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.

What does tooth abrasion look like?

The Signs and Symptoms of Dental Abrasion

Dental abrasion can cause small, v-shaped ridges on the surface of the teeth that face the cheeks. Tooth decay may also be present, and in severe cases, tooth loss may occur. A common symptom of dental abrasion is increased dental sensitivity due to the loss of dental enamel.

Can you stop tooth abrasion?

Unfortunately, dental abrasion cannot be reversed. When tooth enamel wears away, it doesn’t grow back.
