Will secondary dentin develop if the teeth become abraded?

True
False
Only in adults
Only in children

The correct answer is: True

Secondary dentin is a protective dentin that is formed underneath the enamel and is deposited continuously with age. This process occurs in response to natural tooth wear, such as abrasion. Therefore, if teeth become abraded, it is a natural response for secondary dentin to develop in order to protect the tooth. This process occurs regardless of whether the individual is an adult or child. The option stating that secondary dentin only develops in adults or children is incorrect because it can occur in both age groups. Additionally, stating that secondary dentin only occurs in adults or children may imply that it does not develop in the other age group, which is not true. The option stating "False" is incorrect because secondary dentin does develop in response to tooth wear.
