The purpose of this study was to investigate the association between dental office scale and the office's compliance with infection control practices, to serve as reference for policy making by associated government organizations. Proportional random sampling method was used to select 200 dental offices from the 1140 dental offices in Taipei City. Chief dentists from the selected offices were interviewed by well-trained personnel with a 34-item questionnaire that covered items such as compliance and expenses for infection control in dental procedures. One hundred eighty-one questionnaires were returned and analyzed using an SAS/PC software package. The dental offices were divided by size into small, medium and large by dental chair number (≦2,3~4,≧5 respectively). Frequency distribution was used to analyze each item of the questionnaire and the Chi-square test was used to analyze the association between dental office scale and the compliance with infection control practices. The results indicated that:(1)The percentages of large, medium and small dental offices were 7.78%,41.33%, and 50.89%; (2)65.75% of the surveyed dental offices had only one dentist in their offices, 52.49% of the offices had only one dental assistant, and 54.7% of the offices had a disinfection room; (3)Compliance rates for use of mouth mask, gloves, facial mask, and hand washing were 98.90%, 81.22%, 42.54% and 91.71%, respectively while compliance rate for use of autoclave in sterilization of handpieces was 58.56%; (4)68.51% asked for self-performing infection control, 91.71% regarded infection control as absolutely necessary and 51.93% reguarded surcharge of infection control should be paid by dental offices, governments and patient ; (5)The size of dental offices was significantly associated with the need for promoting infection control, surcharge for infection control and attendance at infection control campaigns conducted by the Dental Association, but was not significantly associated with the compliance with barrier techniques for infection control. In conclusion, the Dental Association should more actively encourage infection control education in all dental offices.
