Percutaneous injuries amongst Greek endodontists: a national questionnaire survey.

AIM: To investigate amongst Greek endodontists the incidence of percutaneous injuries, the circumstances associated with them, the therapeutic measures taken after the injuries and their compliance with infection control measures.

METHODOLOGY: One hundred and forty-seven endodontists met the inclusion criteria and were invited to participate in the survey. Personal and professional data, information on percutaneous injuries in the past 5 years and on infection control practices were gathered through interviews based on a questionnaire. Data were analysed using chi-square test, independent samples t-test, one-way anova and Pearson's correlation coefficient. The level of significance was set at P = 0.05.

RESULTS: The response rate was 84%. The injury rate was estimated at 1.35 per endodontist per year. Endodontic files were associated with 37% of the injuries and fingers were injured in 75% of the most recent cases. Medical assistance was sought in 36% of the most recent injuries. Endodontists who always or usually practiced 4-handed endodontics (P = 0.007) as well as those not performing surgical endodontics (P = 0.007) reported significantly fewer injuries. In 91% of the participants, a complete hepatitis B virus vaccination was reported. Gloves, masks, rubber dam isolation and puncture-resistant containers for disposal of sharp instruments were always used by 98%, 94%, 100% and 81% of the respondents, respectively.

CONCLUSIONS: The injury rate was low. The practice of four-handed endodontics was associated with a reduced number of percutaneous injuries; the performance of surgical endodontics increased their incidence. Greek endodontists showed a high level of compliance with infection control measures.
