## Core Concept
Apexogenesis is a dental procedure aimed at preserving the vitality of immature permanent teeth with open apices, typically in young patients. The goal is to allow continued root development and closure of the apex. This procedure involves partial or minimal removal of infected tissue, followed by the placement of a medicament, usually calcium hydroxide or a newer material like MTA (Mineral Trioxide Aggregate) or bioceramic materials, to promote healing and root development.

## Why the Correct Answer is Right
The correct statement about apexogenesis is related to its definition, procedure, and goals. Apexogenesis involves preserving the dental pulp's vitality in immature teeth to allow natural root development and apex formation. This procedure is crucial for young teeth that have been affected by decay, trauma, or other factors leading to pulp exposure but still have a good chance of recovery.

## Why Each Wrong Option is Incorrect
- **Option A:** Without the specific details of option A, it's challenging to directly address why it's incorrect. However, if option A suggests that apexogenesis involves the complete removal of the dental pulp, it would be incorrect because apexogenesis aims to preserve pulp vitality.
- **Option B:** Similarly, without specifics, if option B implies that apexogenesis results in the immediate closure of the root apex, it would be incorrect because the procedure allows for natural root development and apex closure over time.
- **Option C:** If option C states that apexogenesis is only performed on teeth with fully formed roots, it would be incorrect because the procedure is specifically indicated for immature teeth with open apices.
- **Option D:** If option D mentions that apexogenesis involves the use of materials like MTA for promoting root development, it would be a correct statement regarding the procedure, not the false statement we're looking for.

## Clinical Pearl / High-Yield Fact
A key point to remember is that the success of apexogenesis depends on the preservation of a healthy pulp tissue environment, which can be challenging. The procedure is considered a conservative approach to managing immature teeth, aiming to avoid more invasive treatments like root canal therapy that could compromise the tooth's growth.

## Correct Answer: D.
