Few studies analyzed the transmission of bacteria in the dental practice , however there are indirect evidences that this
occurs and it can be obtained from seroprevalence studies
that show that antibodies to a number of viruses found in saliva (such as
cytomegalovirus , influenza virus and respiratory syncytial virus ) are more
common in dentists than in the general population and increase with time. Carriers of bacteria may be asymptomatic, and transmission
to the dental worker and patients can occur if infection control measures, such
as use of gloves, masks, protective eye wear and hand hygiene practices are not
in use.
Prevention of transmission of tuberculosis requires prior
recognition of infected or high-risk patients and prompt referral for diagnosis
and treatment. Elective dental treatment for patients with active tuberculosis
should be delayed until the patient is considered noninfectious. Patients with
active tuberculosis who require emergency dental treatment should be referred to
an appropriate facility.
