Abstract
The ultrasonic dental scaler is a valuable tool in the prevention and treatment
of periodontal disease; however this equipment is associated with a number of hazards.
These include heating of the tooth during scaling, vibrational hazards, possible platelet
damage by cavitation, effects of electromagnetic fields on pacemakers, auditory damage
to patient and most importantly the production of splatter and aerosols.
The possible threat that may be inherited by airborne material during
production of aerosols and splatter include possible risk to patient and dentist. The
ultrasonic scaler is the greatest producer of contaminated aerosols, therefore it is
necessary to recognize and minimize or eliminate these possible hazards to the greatest
feasible extent within a clinical situation.
This paper provides an insight into some of the research conducted in these
areas of associated hazards and different methods to reduce it with relatively simple and
inexpensive procedures
