**Core Concept**
The management of patients on anticoagulant therapy who require dental surgical treatment involves a delicate balance between the risk of bleeding and the risk of thromboembolic events. Anticoagulants, such as warfarin and novel oral anticoagulants (NOACs), increase the risk of bleeding by inhibiting the coagulation cascade.

**Why the Correct Answer is Right**
The dental surgeon should carefully assess the patient's risk of bleeding versus the risk of thromboembolic events and consider discontinuing anticoagulant therapy for a short period before surgery. However, this is not always feasible, especially in patients with a high risk of thromboembolic events. In such cases, the dental surgeon should consult with the patient's physician to determine the best course of action. The American Society of Regional Anesthesia and Pain Medicine (ASRA) guidelines recommend continuing anticoagulant therapy in patients undergoing minor surgical procedures, such as dental surgery, if the risk of bleeding is low.

**Why Each Wrong Option is Incorrect**
**Option A:** Discontinuing anticoagulant therapy without consulting the patient's physician is not recommended, as it may increase the risk of thromboembolic events.
**Option B:** Using a local anesthetic with a vasoconstrictor is not sufficient to manage bleeding in patients on anticoagulant therapy.
**Option C:** Performing the dental surgery without any precautions is not recommended, as it may lead to significant bleeding.

**Clinical Pearl / High-Yield Fact**
When managing patients on anticoagulant therapy who require dental surgical treatment, it's essential to consult with the patient's physician to determine the best course of action. The ASRA guidelines provide a framework for managing anticoagulant therapy in patients undergoing regional anesthesia and pain management procedures.

**Correct Answer:** C.
