摘要

Objectives: This study aimed to survey changes in practices of infection control (IC) procedures by dentists in Beijing between 2000 and 2010. Methods: Data were based on the feedback of 592 and 769 dentists surveyed in 2000 and 2010, respectively. Statistical analysis was conducted using Pearsons chi-squared test. Results: Response rates of 95% (2000) and 94% (2010) were achieved. The percentages of dentists who had received training in IC were 62.96% (2000) and 76.21% (2010). Improvements in practices in 2010 over those in 2000 included increases in: the percentage of vaccination for hepatitis B virus from 32.66% to 68.14%; the routine use of gloves from 73.31% to 99.73%; the use of face shields or eyewear as protection against splatter during dental treatment from 13.94% to 95.45%; the use of protective gowns from 14.51% to 54.23%; the use of high-volume suction from 11.19% to 74.34%; routine changing of gloves between patients from 63.25% to 99.22%; pressured steam sterilisation of dental handpieces between patients from 41.24% to 96.10%, and the flushing of dental unit waterlines after each treatment from 42.01% to 73.49%. Conclusions: Although compliance with recommended IC practices by dentists in Beijing improved between 2000 and 2010, not all dentists are properly familiar with IC procedures. Education in IC in dental schools and in continuing training in hospitals, and mandatory regulations are needed to improve IC practices in dental health care settings.
