How does an antiseptic differ from an antibiotic?

Antiseptics and antibiotics serve distinct roles in the management of infections, particularly regarding their application and the types of pathogens they target. The correct understanding is that antiseptics are primarily used on living tissues to prevent infections, while antibiotics are used to treat infections that are already present inside the body.

Antiseptics are substances that can reduce or eliminate microorganisms on the skin and mucous membranes. They are commonly used in clinical settings for hand hygiene, pre-surgical skin preparation, and cleaning wounds to prevent infection. Because they are intended for use on living tissues, antiseptics must be safe for that context.

In contrast, antibiotics are medications specifically designed to combat bacterial infections within the body. They work internally to inhibit the growth of bacteria or kill them altogether, responding to infections that have already established themselves.

Understanding this distinction highlights why the statement emphasizing the different uses and applications of these agents is accurate. It reflects their roles in preventing versus treating infections, helping dental nursing professionals make informed decisions in clinical practice.
