Environmental surfaces can be divided into clinical contact surfaces and housekeeping surfaces. Clinical contact surfaces can be directly contaminated from patient materials either by direct spray or spatter generated during dental procedures or by contact with gloved hands of dental health care personnel. These surfaces can subsequently contaminate other instruments, devices, hands, or gloves. Housekeeping surfaces (e.g., walls, floors, sinks) are not directly touched during dental treatment and carry the lowest risk of disease transmission.

Recommendations for Cleaning and Disinfecting Environmental Surfaces


What are the types of environmental surfaces in a dental facility?

Environmental Surface Type


Recommendations for Cleaning and Disinfecting*

Clinical contact Light handles
Dental radiograph equipment
Drawer handles
Use surface barriers to protect, particularly for surfaces that are hard to clean, and change barriers between patients. Use surface barriers to speed operatory turnaround.
Clean and disinfect surfaces that are not barrier protected using an EPA-registered hospital disinfectant with a low-level (i.e., HIV and HBV label claims) to intermediate-level (i.e., tuberculocidal claim) activity after each patient. Use an intermediate-level disinfectant if visibly contaminated with blood.
Housekeeping Floors


Clean with a detergent and water or an EPA-registered hospital disinfectant/detergent on a routine basis, and when visibly soiled.

Clean mops and cloths after use and allow to dry before reuse; or use single-use, disposable mop heads or cloths.

Prepare fresh cleaning or EPA-registered disinfecting
solutions daily and as instructed by the manufacturer.

Clean walls, blinds, and window curtains in patient-care areas when they are visibly dusty or soiled.

* High-level disinfectants should never be used on environmental surfaces.
