**Question:** According to Hippocratus-Nelson method, pressure applied for reduction of dislocated mandible:

A. Direct pressure
B. Indirect pressure
C. Oblique pressure
D. Rotational pressure

**Correct Answer:** D. Rotational pressure

**Core Concept:** The Hippocratus-Nelson method is a classic technique for reducing mandibular dislocations. This method involves applying a specific type of pressure to guide the mandible back into its normal position.

**Why the Correct Answer is Right:** In the Hippocratus-Nelson method, the correct pressure to be applied is rotational pressure. This is because when the dislocated mandible is rotated in the correct direction, it helps to realign the jawbone and restore the joint's normal function.

**Why Each Wrong Option is Incorrect:**

A. Direct pressure (Option A) might not be sufficient to displace the displaced mandible back into place, as it focuses on a single direction without the necessary rotational force required for reduction.
B. Indirect pressure (Option B) is not specific enough to guide the mandible back into its proper position, leading to incomplete or unsuccessful reduction.
C. Oblique pressure (Option C) may not effectively guide the mandible into the correct alignment without considering the rotational aspect, resulting in an inaccurate reduction.

**Clinical Pearl:** The Hippocratus-Nelson method is crucial in treating mandibular dislocations, as applying the correct pressure (rotational pressure) allows for successful reduction of the jawbone injury. Inaccurately applying pressure may lead to incomplete reduction or worsening of the condition. This technique is essential for emergency medical professionals to effectively manage mandibular dislocations and restore the patient's dental function.
