HOSA Dental Terminology Practice

Which term describes the process of wearing away?

1. Attenuation

2. Attrition

3. Resorption

4. Osteotomy

The correct answer is: Attrition

The term that describes the process of wearing away is attrition. In dental terminology, attrition specifically refers to the gradual loss of tooth structure due to mechanical forces, typically from chewing and grinding. This wear can lead to a variety of dental issues, including sensitivity, changes in the bite, and an increased risk of cavities or fractures, if not managed properly. Understanding attrition is important for dental professionals as it helps them assess the health of a patient’s teeth and identify lifestyle or dietary factors contributing to excessive wear. For example, bruxism, or teeth grinding, is a common cause of attrition that might require intervention. The other terms, while related to dental processes, refer to different concepts. For instance, attenuation relates to a reduction in force or intensity, often used in the context of radiation or sound. Resorption involves the process where the body breaks down and assimilates tissue, which is relevant in orthodontics and dental health but does not describe wear. Osteotomy is a surgical procedure where a bone is cut to allow for realignment or correction, mostly in orthopedic or dental surgery contexts.
