Tuberculosis risk in the hospital dental practice.

Abstract

Tuberculosis has re-emerged as a serious public health concern. Multidrug-resistant strains and an increase in the number of high-risk groups are posing a difficult problem for health care providers. The risk of TB transmission in hospital dental practices is potentially increasing. A 20-question survey was mailed to the membership of the American Association of Hospital Dentists, addressing various issues relating to tuberculosis. One hundred thirty-two surveys were analyzed. Twelve per cent of respondents reported at least one TB skin test conversion by a dental provider within the past year at their institution. Five respondents reported one dental provider contracting TB through patient contact. Oral TB was reported in 21 cases. Over 34% reported that active TB patients are not isolated to negative-pressure isolation rooms, 45% reported that patients are allowed to frequent public areas, and only 59% believed that drug compliance monitoring was adequate. Over 86% support TB screening in the Hospital Dental Practice. It was concluded that Hospital Dental Practice personnel may be at increased risk for exposure to TB. Dental providers must exercise strict TB prevention and employ meticulous referral and follow-up procedures for high-risk patients.
