How much higher is the assistant's eye level compared to the dentist when seated?

When seated, the assistant's eye level is typically higher than that of the dentist due to the ergonomic arrangement of the dental operatory. This height difference often allows the assistant to have a clear line of sight to both the dentist's work and the patient's mouth, facilitating better communication and support during dental procedures.

An eye level difference of four to six inches is commonly found in practice, as assistants generally sit on stools that are adjustable, allowing them to achieve optimal positioning relative to the dentist. This four to six inch range strikes a balance, ensuring the assistant can perform their duties effectively while still being low enough to avoid obstruction of the dentist's work field.

Understanding this height difference is essential for maximizing efficiency in the dental practice, as it enables better teamwork and enhances the workflow during procedures.
