What is the difference between tooth 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 a tooth abfraction?

Dental abfractions are v-shaped notches that appear near the gingival margin. These lesions are not caused by decay. Rather, they are the result of certain dental conditions, such as bruxism (teeth grinding).

What is a 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.

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.

Tooth erosion, abfraction, attrition and other dental wear ©

What is the difference between attrition and abfraction?

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

What are the two types of abrasion?

What is gingival abrasion?

gin·gi·val a·bra·sion. a lesion of the gingiva resulting from mechanical removal of a portion of the surface epithelium.

How is a dental abrasion diagnosed?

How is tooth abrasion treated?

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.

Is abfraction a cavity?

Abfractions are not cavities but are instead known as non-carious cervical lesions or NCCL. However, because they expose the softer portions of the teeth, like dentin, they can cause tooth sensitivity and mimic the symptoms of a cavity.

When do you treat abfraction?

Treatments for Abfraction

If left untreated, abfraction lesions can lead to tooth decay, root canal infections, and tooth loss. Treating abfraction as early as possible is essential for protecting your oral health.

Are tooth abfractions common?

Dental abfractions are actually among the most common of all dental problems. They are the notches that occur in the teeth at the gum line.

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.

What is the difference between attrition and bruxism?

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 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 causes abfraction?

Abfraction is caused by long-term stress on the teeth. This can happen in a variety of ways, such as: bruxing, also known as teeth grinding. misalignment of the teeth, also called malocclusion.

Can electric toothbrush cause abrasion?

Results. The power toothbrushes caused significantly higher dentin abrasion compared to the manual toothbrushes using the same brushing force and time.

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.

What are some examples of abrasion?

A scraped knee is an example of an abrasion. Other examples include road rash, raspberries, strawberries, and injuries such as a cheese grater or sandpaper could create.

What is the difference between abrasion and wear?

Although the terms are frequently used interchangeably, wear is "the wearing away of any part of a material by rubbing against another surface"[2] and abrasion is the action that causes it.

What are three things that can cause abrasion?

Water, wind, and gravity can cause abrasion. Water can cause abrasion by moving rocks and making them hit each other.

What causes abrasion of the tooth structure?

Abrasion is the wearing away of tooth surface caused by friction or a mechanical process. Abrasion happens when teeth are brushed too vigorously in sweeping horizontal strokes. The use of a hard toothbrush can also cause the problem.

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.

Can flossing cause abfraction?

Aggressive Brushing and Flossing – Aggressive brushing and flossing can increase your risk of worn tooth enamel and gum recession. In addition, it can potentially quicken the formation of abfractions given the stress placed on the teeth along the gumline.
