What type of dental lesion may present as abrasion on the anterior teeth?

Traumatic abrasion is a type of dental lesion that occurs due to mechanical forces acting on the teeth. It is often caused by habits such as aggressive tooth brushing, the use of hard-bristled toothbrushes, or objects like pens or fingernails being used on the teeth. This can lead to visible wear and tear on the enamel surface, particularly on the anterior teeth, resulting in an appearance that resembles a form of abrasion.

In contrast, fluorosis is a condition resulting from excessive fluoride exposure during tooth development, characterized by discoloration and enamel mottling rather than abrasion. Dental caries is a decay process that creates cavities in teeth, presenting as dark spots or holes rather than surface wear. Erosion involves the loss of tooth structure due to chemical processes, often related to dietary acids, which can also affect teeth but has a different appearance compared to abrasion caused by mechanical factors.

Thus, traumatic abrasion specifically describes lesions resulting from physical wear, particularly noticeable on the anterior teeth, making it the correct choice in this context.
