Antimicrobial Mechanisms Antimicrobial agents have a variety of mechanisms of action. Each mechanism inhibits a key structural or metabolic function. Dental practitioners employ antiseptics such as chlorhexidine (CHX) as antimicrobial agents. CHX exhibits its effects on cell surfaces. The cationic nature of CHX gives it several valuable properties: it sticks to anionic oral surfaces, it
