Aim:
The aim is to present the essential elements of an infection control/exposure control plan for the oral healthcare setting with emphasis on tuberculosis (TB).
Methods And Materials:
A comprehensive review of the literature was conducted with special emphasis on TB infection-control issues in the oral healthcare setting.
Results:
Currently available knowledge related to TB infection-control issues is supported by data derived from well-conducted trials or extensive controlled observations. In the absence of supportive data the information is supported with the best-informed, most authoritative opinion available.
Conclusion:
Essential elements of an effective TB infection-control plan include a three-level hierarchy of administrative, environmental, and respiratory-protection controls.
Clinical Significance:
Standard precautions provide the fabric for strategies to prevent or reduce the risk of exposure to bloodborne pathogens and other potentially infectious material. However, standard precautions are inadequate to prevent the spread of organisms through droplet nuclei 1-5 micron in diameter and additional measures are necessary to prevent the spread of Mycobacterium tuberculosis. Oral healthcare settings have been identified as outpatient settings in which patients with suspected or confirmed infectious TB disease are expected to be encountered. Therefore, oral healthcare settings must have a written TB infection-control program.

Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
