During preparation, which item should NOT be placed on the dental chair?

The reasoning behind avoiding placing food items on the dental chair stems from the principles of infection control and patient safety. Food items can introduce contaminants and increase the risk of cross-contamination in a dental setting. Dental offices are environments that require strict cleanliness, and the presence of food can lead to the spread of bacteria, viruses, or other harmful pathogens.

By keeping the dental chair free of food items, the risk of exposing patients and staff to potential allergens or foodborne illnesses is minimized. In contrast, items such as cotton rolls, image receptors, and film holders are integral to the dental procedure and are designed for single-use or disinfected handling, making them acceptable for placement on the dental chair in preparation for treatment. Ensuring that the chair remains hygienic is an essential aspect of maintaining a safe and effective dental practice.
