**Core Concept**
CVEK pulpotomy, also known as a Cvek pulpotomy, is a specific dental procedure used to treat traumatic injuries to the immature permanent teeth. This technique involves removing the infected pulp tissue from the coronal portion of the tooth while preserving the vitality of the remaining pulpal tissue in the root canal.

**Why the Correct Answer is Right**
The Cvek pulpotomy is indeed known by several names, including partial pulpotomy and cervical pulpotomy. These names refer to the procedure's focus on removing infected pulp tissue from the coronal portion of the tooth. The term "cervical pulpotomy" specifically emphasizes the location of the procedure, which is at the cervical margin of the tooth. The Cvek pulpotomy is distinct from a traditional pulpotomy, which involves removing all infected pulp tissue from the tooth.

**Why Each Wrong Option is Incorrect**
**Option A:** "Partial pulpotomy" is actually a synonym for CVEK pulpotomy, as it refers to the removal of infected pulp tissue from the coronal portion of the tooth, preserving the vitality of the remaining pulpal tissue in the root canal.
**Option B:** "Cervical pulpotomy" is also a correct term for CVEK pulpotomy, emphasizing the location of the procedure at the cervical margin of the tooth.
**Option C:** "Pulp curettage" is not a commonly used term for CVEK pulpotomy, although it might be considered a related procedure in some contexts. However, it is not a widely recognized or standard term for this specific technique.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the primary goal of a Cvek pulpotomy is to preserve the vitality of the remaining pulpal tissue in the root canal, which is crucial for the continued development and long-term health of the immature permanent tooth.
