Answers

1. Correct answer C: Social handwashing involves the use of general-purpose soap (rather than a special antibacterial hand cleanser) that is worked into a lather to physically clean the hands. This action will remove any general microorganisms from the hand surfaces, such as those acquired by using door handles in public places, taps and toilet flush handles and so on.
2. Correct answer C: Aerosol spray and particle spatter are everyday occurrences during the delivery of dental treatment and are always likely to occur in this environment. Direct contact with some body fluids (such as saliva or respiratory tract discharge) may occur outside of the immediate clinical area simply by contact with the public, as happens anywhere. However, inoculation injuries should be a rare occurrence if the infection control policy is followed correctly by all dental personnel.
3. Correct answer A: There are many diseases that can be transmitted without every sufferer becoming ill immediately (if at all), and the infected person is then often unaware that they have been exposed to pathogens. However, they can still pass the disease onto a third person by any of the usual routes of transmission, and that person will also then become infected. This intermediary who shows no signs of disease nor suffers any symptoms is called a carrier, and the likelihood of a healthy carrier unknowingly being treated at some point in a dental workplace forms the basis of the principles of ‘standard precautions’ – to treat every...
