Sitemap All dental health care personnel engaged in direct patient-care in the operatory area must use Personal Protective Equipment (PPE) (e.g., gloves, masks, protective eyewear or face shield, and gowns). All PPE should be removed before leaving patient-care areas. Masks should be changed between patients and disposable gowns when visibly soiled or penetrated by other potentially infectious materials. NCMOM supplies gloves, cone and ear loop masks, disposable gowns and safety glasses. You may want to bring your own safety glasses.
