## Core Concept
Interglobular dentin is a characteristic feature observed in the dentin layer of teeth. It results from the pattern of dentin formation, specifically related to the mineralization process. Understanding its formation is crucial for dental anatomy and histology.

## Why the Correct Answer is Right
The correct answer, **D. Incomplete mineralization between dentin globules**, is right because interglobular dentin represents areas where the mineralization of dentin is incomplete. During dentinogenesis, dentin globules form and then fuse. However, if the mineralization process is incomplete, spaces or areas between these globules remain less mineralized, creating interglobular dentin. This phenomenon is particularly noted in the mantle dentin.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incorrect because it does not accurately describe the process leading to interglobular dentin formation.
- **Option B:** This option is incorrect as it does not relate to the known mechanisms of interglobular dentin formation.
- **Option C:** This option is incorrect because it does not accurately represent the cause of interglobular dentin.

## Clinical Pearl / High-Yield Fact
A key point to remember is that interglobular dentin is a normal variant and can be seen in teeth, especially in the early formed dentin. It is an important feature to recognize in dental histology sections. Clinically, it's essential to differentiate it from other dentinal defects or pathologies.

## Correct Answer Line
**Correct Answer: D. Incomplete mineralization between dentin globules**
