**Core Concept**
The "hand over mouth" technique refers to a method in dental care where a dentist or caregiver uses one hand to support the patient's head and the other to apply gentle pressure over the mouth, facilitating better control during procedures like suctioning or positioning. This technique is foundational in pediatric and clinical dentistry for ensuring patient comfort and safety.
**Why the Correct Answer is Right**
Dr. Evangeline Jordan, an early 20th-century American dentist, first described the "hand over mouth" technique in the context of managing pediatric patients. Her work emphasized gentle, controlled handling of children during dental procedures, reducing anxiety and improving cooperation. The technique involves placing one hand over the child’s mouth while supporting the head, allowing for better access and control without causing discomfort.
**Why Each Wrong Option is Incorrect**

Option C: Dr. G.V. Black is renowned for developing dental restorations and the Black classifications of cavities, unrelated to patient handling.
Option D: Dr. Goldman contributed to dental hygiene and public health, not the hand-over-mouth technique.
**Clinical Pearl / High-Yield Fact**
In pediatric dentistry, the hand-over-mouth technique is a simple yet effective method to calm anxious children and ensure proper positioning during treatment—always performed with gentle, non-invasive handling.
