**Core Concept**
The management of a tooth with a fractured crown and pulp exposure involves evaluating the extent of pulp damage and choosing an appropriate treatment to preserve the tooth. This may involve endodontic therapy, restorative dentistry, or a combination of both.

**Why the Correct Answer is Right**
The correct answer is a treatment that cannot be performed on a tooth with a fractured crown and pulp exposure. In such cases, the primary goal is to relieve pain, prevent infection, and preserve the tooth. Endodontic therapy, including obturation and root canal treatment, is a common treatment option for teeth with pulp exposure. Restorative dentistry, including crowns and fillings, is also used to repair the tooth structure. However, certain treatments may not be feasible or may even be contraindicated in the presence of a fractured crown and pulp exposure.

**Option C:** This option is incorrect because it is a common treatment for teeth with pulp exposure, including those with fractured crowns.

**Clinical Pearl / High-Yield Fact**
In cases of pulp exposure, it's essential to evaluate the extent of pulp damage and choose a treatment that preserves the tooth. A thorough examination, including radiographs and clinical evaluation, is necessary to determine the best course of action.
