Recent non-sterile inoculation injuries to dental professionals in the Lothian region of Scotland.
A retrospective study of inoculation injuries in dental practice was conducted by means of a questionnaire distributed to 310 dental practitioners in the Lothian region of Scotland. Recent injuries were independently classified by a hospital dentist, general dental practitioner and immunologist as constituting high, moderate or low risk of transmission to the dentist. A consultant physician in infectious diseases assessed the follow-up actions. The results indicate that non-sterile inoculation injuries are a common hazard of dental practice with 56% of respondents reporting at least one such injury within the last year. A total of 30% of reported injuries constituted a moderate or high risk of transmission to the dental practitioner. Action taken following such injuries was often considered to be inadequate. While many injuries could possibly be avoided by changes in surgery design, avoidance of other injuries would probably require fundamental changes in routine dental practice. While the incidence of such injuries is high, dental practice within the UK appears to be associated with a low risk of acquiring HIV infection by occupational exposure. The increasing awareness of the importance of other blood-borne viral infections makes this a continuing issue.
