Dental hygienists work in
clean, well-lighted offices. Important health safeguards include strict
adherence to proper radiological procedures, and the use of appropriate
protective devices when administering anesthetic gas. Dental hygienists also
wear safety glasses, surgical masks, and gloves to protect themselves and
patients from infectious diseases.
