DANB General Chairside Practice Test

Which of the following statements does not align with the concepts of four-handed dentistry?

1. Use a slim patient chair back

2. Maintain an ergonomic position

3. Use a wide-winged patient chair back

4. Keep essential tools within reach

The correct answer is: Use a wide-winged patient chair back

The concept of four-handed dentistry emphasizes the efficiency and ergonomics of dental procedures, primarily through the collaboration of the dentist and the dental assistant. The aim is to create a work environment that minimizes strain and maximizes the accessibility of tools, leading to improved patient care and comfort. Using a slim patient chair back is consistent with four-handed dentistry because it allows for easy access and maneuverability for both the dental team and the patient. Maintaining an ergonomic position is crucial in preventing repetitive strain injuries amongst dental professionals, ensuring that both the dentist and the assistant can work together comfortably and effectively. Keeping essential tools within easy reach is vital for reducing delays during procedures and enhancing the overall workflow. A wide-winged patient chair back does not align with the principles of four-handed dentistry. Such a design could restrict movement and access, making it difficult for the dental assistant to assist effectively during procedures. This could lead to inefficient workflows and potentially affect the quality of patient care, as it hinders the ergonomic setup and the seamless coordination between the dentist and the assistant.
