What does the term 'internal resorption' signify?

1. Destruction of tooth enamel

2. Destructive process from within the tooth

3. Loss of the periodontal ligament

4. External decay of the tooth

The correct answer is: Destructive process from within the tooth

The term 'internal resorption' specifically signifies a destructive process that occurs from within the tooth structure. It is characterized by the breakdown of the tooth’s internal dentin and pulp tissue, usually due to inflammation or other pathologic conditions. This process can lead to changes in the tooth's shape and potentially threaten its integrity if not addressed. Internal resorption is often associated with trauma or chronic inflammation, indicating that it originates from the tooth's internal environment rather than affecting external surfaces or supporting structures. Understanding this concept is crucial for diagnosing and treating dental conditions that compromise tooth health from the inside out.
