Many hazards are often associated with different occupations and known as occupational hazards.
Dentistry is also one of those professions having many occupational risks. Such hazards are broadly
categorized into chemical, biological, physical, mechanical and psychological factors. Cross infection is
one of such hazards faced by the health care providers’ particularly dental workers. Cross infection is the
transmission of infectious agents between patient and staff in clinical environment. Control of cross infection
has remained the major concern of the dental community for decades. Various vectors are involved in cross
infections in Dentistry including patients, environment (water, air), instruments etc. Particularly among the
environmental factors, airborne route is one of the major routes of cross contamination and so aerosols
produced in dental environment carry greatest pathogenic potential. Production of aerosols and splatters
occur because of many procedures carried out in mouth including crown preparation, ultrasonic scaling,
caries excavation etc. Patients, dental instruments and dental unit waterlines (DUWL) are the important
sources of contaminated aerosol production in dental operatory. Use of personal Protective equipments,
regular use of pre-procedural mouth rinses and high evacuation devices are few of the suggested methods
to reduce risk of cross contamination especially through aerosols and splatters in the dental offices. The
related articles were searched through PubMed and Google Scholar.
