Infection Control Guide for Dental Assistants

Ready to elevate your infection control protocols? Let’s dive into the essential practices that ensure a safe and sterile dental environment.


Infection control measures in dental practices protect against the transmission of infectious diseases. These practices are critical for:

PATIENT SAFETY: Preventing the spread of infections during dental procedures.

STAFF PROTECTION: Safeguarding dental staff from potential exposure to pathogens.

REGULATORY COMPLIANCE: Meeting the standards set by health authorities and professional bodies.


1. Hand Hygiene

Effective hand hygiene is the cornerstone of infection control. Dental assistants should:

Wash Hands Properly: Use soap and water, scrubbing for at least 20 seconds, before and after patient contact, and after removing gloves.

Use Hand Sanitizer: When soap and water are unavailable, use an alcohol-based hand sanitizer with at least 60% alcohol.

Avoid Touching Your Face: Minimize touching your face, especially the eyes, nose, and mouth, to reduce contamination risk.

2. Personal Protective Equipment (PPE)

Proper use of PPE is essential to protect both patients and staff. Dental assistants should:

WEAR GLOVES: Always use disposable gloves during patient care and when handling contaminated items. Change gloves between patients.

USE MASKS AND FACE SHIELDS: Protect against respiratory droplets by wearing masks and, when necessary, face shields.

DON GOWNS: Wear disposable or reusable gowns to protect clothing and skin from contaminants.

EMPLOY EYE PROTECTION: Use safety goggles or face shields to protect your eyes from splashes and sprays.

3. Instrument Sterilization

Sterilizing dental instruments is vital for infection control. Dental assistants should:

CLEAN INSTRUMENTS THOROUGLY: Use ultrasonic cleaners or other appropriate methods to clean instruments before sterilization.

USE AUTOCLAVES: Sterilize instruments in an autoclave, following manufacturer instructions for proper use and maintenance.

MONITOR STERILIZATION CYCLES: Ensure sterilization efficacy by regularly checking cycle parameters and using biological indicators.

4. Surface Disinfection

Keeping surfaces clean prevents cross-contamination. Dental assistants should:

DISINFECT HIGH-TOUCH AREAS: Regularly disinfect surfaces such as dental chairs, countertops, and equipment with EPA-approved disinfectants.

FOLLOW PROPER PROTOCOLS: Ensure surfaces are cleaned before disinfecting, and adhere to contact time recommendations for disinfectants.

MAINTAIN CLEAN ENVIRONMENTS: Keep treatment areas tidy and free of unnecessary items to facilitate thorough cleaning.

5. Safe Injection Practices

Safe injection practices prevent the transmission of infections through bloodborne pathogens. Dental assistants should:

USE STERILE EQUIPMENT: Always use new, sterile needles and syringes for each injection.

DISPOSE OF SHARPS PROPERLY: Place used needles and other sharps in designated puncture-resistant containers immediately after use.

6. Waste Management

Proper waste disposal is crucial for maintaining a sterile environment. Dental assistants should:

Segregate Waste: Separate general waste from biohazardous waste, following local regulations.

Use Appropriate Containers: Dispose of biohazardous waste in clearly labeled, leak-proof containers.

Handle Waste Safely: Avoid overfilling waste containers and ensure they are securely sealed before removal.

7. Continuous Education and Training

Staying informed about the latest infection control protocols is essential. Dental assistants should:

Participate in Training Programs: Attend workshops, seminars, and online courses to stay current with best practices.

Review Guidelines Regularly: Keep up-to-date with guidelines from the CDC, OSHA, ADA, and other relevant organizations.

Engage in Peer Learning: Share knowledge and experiences with colleagues to foster a culture of continuous improvement in infection control.


Adhering to best practices for infection control is vital for the health and safety of patients and dental staff.
