## **Core Concept**
Peri-implantitis and peri-implant mucositis are two conditions associated with inflammatory changes around dental implants. Peri-implant mucositis is characterized by inflammation of the mucosa surrounding the implant, while peri-implantitis involves inflammation of the mucosa and loss of supporting bone.

## **Why the Correct Answer is Right**
The correct answer, peri-implant mucositis, is a condition specifically referring to inflammatory changes in the soft tissues surrounding a dental implant. This condition is similar to gingivitis in natural teeth and is reversible with treatment. It does not involve bone loss, distinguishing it from peri-implantitis.

## **Why Each Wrong Option is Incorrect**
* **Option A:** Peri-implantitis involves not only inflammation of the soft tissues but also loss of the supporting bone around the implant, making it a more severe condition than what is described.
* **Option B:** This option might seem plausible but does not accurately describe a commonly recognized condition related to dental implants.
* **Option D:** This option does not correspond to a recognized condition related to dental implants.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that peri-implant mucositis is a reversible condition if treated promptly. Regular monitoring and maintenance are crucial for preventing progression to peri-implantitis. The presence of bleeding on probing and increased probing depth are indicators of peri-implant mucositis.

## **Correct Answer:** . Peri-implant mucositis
