Which system is stressed and strained when a dental assistant assists with dental procedures?

The muscular system is significantly stressed and strained when a dental assistant assists with dental procedures for several reasons. First, dental assisting often requires prolonged periods of standing, which can lead to muscle fatigue. The assistant must maintain specific postures, such as leaning over a patient or reaching for instruments, which can put strain on various muscle groups, particularly in the back, shoulders, and arms.

Additionally, dental assistants frequently perform repetitive motions, such as passing instruments or assisting the dentist with specific tasks, leading to increased tension and stress on the muscles. This physical demand can contribute to an increased risk of musculoskeletal disorders over time if proper ergonomics and body mechanics are not employed.

While the cardiovascular and nervous systems certainly play roles in overall health and performance during such tasks, it is the constant engagement and demand placed on the muscles that most directly relates to the stresses experienced during dental procedures. The digestive system, on the other hand, is not directly involved in the physical actions required during these tasks.
