## Core Concept
Osteogenesis imperfecta (OI) is a group of genetic disorders characterized by **brittle bones**, **increased bone fragility**, and **extraskeletal features** such as blue sclerae, dental abnormalities, and hearing loss. The condition primarily affects the production of **collagen**, a crucial protein for bone structure.

## Why the Correct Answer is Right
The correct answer relates to the understanding that OI is caused by mutations in the genes that encode for **type I collagen** (COL1A1 and COL1A2). This leads to defective collagen production, which is essential for bone strength and structure. Understanding the genetic basis helps in identifying the incorrect statement regarding OI.

## Why Each Wrong Option is Incorrect
- **Option A:** Typically, OI is associated with **blue sclerae** due to the transparency of the sclera, which allows the underlying veins to be visible. This condition is a classic feature, making statements contradicting this association incorrect.
- **Option B:** OI often presents with **dental abnormalities**, such as dentinogenesis imperfecta, which leads to discolored teeth. A statement denying dental issues would be incorrect.
- **Option C:** **Hearing loss** is a common feature in OI, often presenting as a conductive or mixed hearing loss. Denying the association of OI with hearing loss would be incorrect.

## Clinical Pearl / High-Yield Fact
A key clinical pearl is that OI is often classified into several types based on clinical and radiological features, with **type I** being the mildest and **type II** being the most severe form, often lethal in infancy. Recognizing these types and their implications on management and prognosis is crucial.

## Correct Answer Line
**Correct Answer: D.**
