Which adjustment can be made to a dental chair to enhance patient comfort?

• A. Changing chair height only
• B. Adjusting the backrest angle
• C. Modifying the armrests
• D. Adding a footrest

Answer: (B)

Adjusting the backrest angle is a key adjustment that can significantly enhance patient comfort in a dental chair. The backrest angle determines how well-supported the patient feels during a procedure, particularly for longer visits. A properly positioned backrest allows the patient to maintain a relaxed posture, minimizing strain on the back and neck. This comfort can help to reduce anxiety, increase patient cooperation, and improve the overall experience during dental treatment.

Other potential adjustments, while they can contribute to comfort, do not address the primary issue of supporting the patient's upper body as effectively as the backrest. For example, changing chair height may ensure that the dentist can work more conveniently, but if the backrest angle is not conducive to the patient's comfort, adjustments in height alone won't be sufficient. Similarly, modifying the armrests or adding a footrest can improve comfort levels, but these changes typically do not have the same immediate impact on upper body support as adjusting the backrest angle does.
