Prevalence of percutaneous exposure incidents amongst dentists in Queensland

Percutaneous exposure incidents (PEI) represent an important occupational health issue in dentistry, and one that can incur severe consequences from blood-borne infections. Given the importance of this topic, we considered it necessary to investigate the distribution and cause of PEI among Queensland dentists.

In 2004, a self-reporting questionnaire was mailed to a random sample of 400 dentists on the register of the Queensland Branch of the Australian Dental Association.

A total of 285 questionnaires (73.1 per cent) were completed and returned. Of the respondents, 73.3 per cent were male and 26.7 per cent female, with a mean age of 45.2 years (SD = 11.9 years). Most were general dentists (89.1 per cent) with the remainder being specialists (10.9 per cent). More than three-quarters (78.5 per cent) reported damaging their gloves at least once during a clinical procedure in the previous 12-month period. Roughly one-quarter (27.7 per cent) had experienced at least one 'sharps' or needlestick injury in the previous 12 months, 16.1 per cent of which involved a contaminated instrument that had been previously used on a patient. The most common devices to cause 'sharps' injury in the previous 12 months were needles (14.4 per cent) and burs (10.2 per cent).

Although PEI clearly remains a major occupational health problem for Queensland dentists, the prevalence of needlestick injuries appears to be lower than other studies from developed countries. The identification of needlestick injuries as a common cause of PEI again stresses the importance of preventive strategies with respect to potential blood-borne infections. Further research is now needed to more carefully identify effective measures for reducing PEI among dental personnel.
