What is the main cause of wedge-shaped lesions in teeth?

Abfraction

How can active erosion lead to dentine hypersensitivity?

Remove the surface smear layer from exposed dentine, opening the dentinal tubules

What is one way to determine the activity of erosion on enamel surfaces?

Scratch test over a short time period

What is erosion in dental terms?

Erosion (corrosion) is the chemical dissolution of tooth substance without the presence of dental plaque. Signup and view all the answers

How do the acids of plaque and acids causing erosion differ in terms of action?

Plaque acids act over relatively long periods, causing subsurface demineralization, while acids causing erosion act on tooth surfaces over short periods, affecting only the surface with little subsurface damage. Signup and view all the answers

What are the sources of acids that cause tooth erosion?

Acids causing tooth erosion can originate from inside the body as gastric acid (intrinsic) or outside the body as dietary, environmental, or occupational acids (extrinsic). Signup and view all the answers

What factors affect the severity of tooth erosion?

The source of acid (intrinsic, extrinsic) and the frequency of exposure are factors that affect the severity of tooth erosion. Signup and view all the answers

What are the general erosive patterns observed clinically in cases of vomiting?

In cases of vomiting, generally, the palatal surfaces of all the maxillary teeth are affected most due to the tongue covering the mandibular teeth during vomiting. Signup and view all the answers

How does the speed of action differ between plaque acids and acids causing erosion?
