What is the difference between abrasion and abfraction?

An abfraction is an angular notch at the gumline caused by bending forces applied to the tooth. An abrasion is a rounded notch at the gumline that may be visibly indestinguishable from an abfraction, although in cross-section abrasions are generally not as angular and have more of a saucered appearance.

What is the difference between dental attrition abfraction erosion and abrasion?

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 the difference between abrasion and erosion?

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.

What is an abfraction?

Abfraction (AF) is the pathological loss of tooth substance caused by biomechanical loading forces that result in flexure and failure of enamel and dentin at a location away from the loading.

What is the difference between attrition and abrasion dental?

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.

Abfraction vs Abrasion with Claire Jeong, RDH, MS

What causes dental Abfraction?

Abfraction is caused by stress and pressure applied to the teeth through biting, chewing, clenching the teeth, and most commonly, teeth grinding. These forces put great stress on the teeth near the gum line, where the enamel and cementum of the teeth meet.

How is abfraction treated?

To treat a dental abfraction, the lesion is filled, much like a cavity. Your dentist will apply composite resin material to the affected area before shaping it and curing it with a special dental light. Finally, the tooth will be smoothed and polished to a natural-looking shine.

What is abrasion of teeth?

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 is cervical abrasion?

Cervical abrasion is non-carious (dental tissue lost near the cementoenamel junction (CEJ)), mechanical wear of teeth due to external forces other than tooth-tooth contact. It most commonly affects teeth along the cervical margins, in most cases, it affects the premolars and canines.

Is abfraction common?

Although abfractions are fairly common occurrences in adult teeth, it may be that you have never heard the term because these V-shaped notches that occur along the gum line often cause no pain and require no treatment.

What are the two types of abrasion?

What is the difference between abrasion and attrition in geography?

Abrasion - this is when pebbles grind along a rock platform, much like sandpaper. Over time the rock becomes smooth. Attrition - this is when rocks that the sea is carrying knock against each other. They break apart to become smaller and more rounded.

What is the difference between abrasion and solution?

Abrasion is where pebbles and small material in the sea grind along a rock platform. It is gradual and has a similar action to sandpaper. Over time, the rock becomes smooth and worn. Solution is when sea water or chemicals in the sea can dissolve rock.

What type of erosion is abrasion?

Abrasion is a process of erosion which occurs when material being transported wears away at a surface over time. It is the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials.

What is the difference between fusion and Gemination?

Gemination and fusion are the most commonly encountered anomalies in dental practice, and distinction between the two is always challenging. Fusion is when two tooth buds fuse to make a large tooth. Gemination, also called double tooth is an anomaly exhibiting two joined crowns and usually a single root.

What does dental abrasion look like?

Abrasion typically looks like a wedge or V-shaped indentation of the tooth at the gum margin, and it appears worn, shiny and is often discolored at the cervical margin.

What causes cervical abrasion?

Cervical ectropion happens when cells from inside the cervical canal grow onto the outside of the cervix. These cells are called glandular cells. Glandular cells are red, so the area may look red. Cervical ectropion is sometimes called cervical erosion or cervical ectopy.

What is Dentinogenesis imperfecta?

Dentinogenesis imperfecta is a disorder of tooth development. This condition causes the teeth to be discolored (most often a blue-gray or yellow-brown color) and translucent.

What is abrasive in dentistry?

A dental abrasive is an important part of dental services. This specialty deals with the finishing and polishing of dental appliances like complete dentures, removable partial dentures, crown and bridges and the direct dental restorative materials.

How is tooth abrasion treated?

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.

What is Turner's hypoplasia?

Turner's Tooth, also called Enamel Hypoplasia by professionals in the field, is a condition that reduces a tooth's enamel thickness, increases tooth sensitivity, leaves the affected tooth more susceptible to decay, and results in an unsightly appearance.

Should you fill abfraction?

Fillings that are due to decay, abfraction, or preventative should not be put off as the conditions that warranted the fillings will progressively get worse with time. A filling done for cosmetic reasons is the only filling that may be planed further in the future.

Is abfraction reversible?

Common Treatment for Abfractions

Once an abfraction lesion develops, the damage cannot be reversed. However, there are treatments that can smooth and enhance the tooth's appearance, reduce dental sensitivity, and help prevent further damage.

What is abrasion in geography rivers?

Abrasion - When pebbles grind along the river bank and bed in a sand-papering effect. Attrition - When rocks that the river is carrying knock against each other. They break apart to become smaller and more rounded.

What is abrasion in geography?

Definition: Abrasion is a process of erosion which can happen in four different ways. The first type of abrasion is caused by ice or glaciation. As a glacier moves, it erodes away at the land surrounding the ice. This is a slow process. The second type of abrasion is caused by rivers.
