Which type of resorption occurs in cases of inflammatory response after avulsion?

• A. Surface resorption
• B. Internal resorption
• C. Replacement resorption
• D. Inflammatory resorption

Answer: (D)

Inflammatory resorption is a specific type of tooth resorption that occurs as a direct response to inflammation, commonly seen in cases of dental trauma such as avulsion. When a tooth is avulsed, the surrounding tissues can become inflamed, leading to the release of inflammatory mediators that stimulate the resorptive processes in the dental tissues.

This type of resorption affects the external root surface and is characterized by the action of osteoclasts that degrade the tooth structure. Inflammatory resorption can compromise the tooth's integrity if not managed properly, as it can lead to significant loss of tooth structure and ultimately affect the survival of the tooth.

Understanding the mechanisms of inflammatory resorption is crucial for dental professionals as it informs treatment options and outcomes, particularly in managing avulsed teeth and their subsequent healing processes. Other types of resorption, such as surface or internal resorption, are indicative of different pathological processes and do not directly correlate with the inflammatory response seen in cases of avulsion.
