Introduction to human body systems: Dental assisting

The human body is organized into systems that work together to support the essential physiological processes – or the normal functions that help the body stay balanced, respond to stress, and support healing. As a dental assistant, your knowledge of human body systems and how they function is crucial as you assist the dental team to provide safe, effective care.

Let’s take a look at how you’ll use your knowledge of body systems and physiology in your practice as a dental assistant. First, this knowledge will help you understand the medical conditions listed in your patient’s medical histories and how these conditions affect your patient. You’ll also understand the common side effects of medications prescribed to your patient and how they can impact your patient’s oral health. For instance, some medications can alter bleeding and healing, while others can cause enlargement of the gums or promote xerostomia, otherwise known as dry mouth.

Knowing how the body normally functions also helps you recognize when a patient’s response to treatment is outside what’s normally expected, such as changes in breathing or skin color. These observations are critical for preventing complications and clearly communicating your concerns to the dental team.

Your knowledge of physiology also reinforces the importance of infection control, helps you to be better prepared to follow infection control protocols, and understand why adhering to safety measures is essential.
