The assessment of adherence to infection control in oral radiology using newly developed and validated questionnaire (QICOR).

OBJECTIVES:: To assess the infection control in oral radiology among radiologists and dentists of diverse dentistry clinical specialties and among dentistry students.

METHODS:: A Questionnaire on Infection Control in Oral Radiology was applied to 1006 dentists and 1203 dentistry students. For assessment of infection control, the scores of the questionnaire were dichotomized in high and low through the median. Simple logistic regression models were set for adherence to infection control and independent variables, estimating the crude odds ratios with the respective 95% confidence intervals. The variables with p < 0.20 in the individual analyses were tested in multiple logistic regression models, remaining in the final model the variables with p ≤ 0.05.

RESULTS:: Individual and adjusted association analysis showed that female dentists have 1.41 ([95% CI: 1.08-1.84)] more adherence odds to infection control when compared with males (p < 0.05). There was no significant association in regarding age, time of education in dentistry, an undergraduate degree from a public or private school, and work in public and/or private clinics. There were also no differences among radiologists and dentists of other clinical specialties. The students from the last year of the dental schools had 1.7 [95% CI (1.13-2.57)] more chances of less adherence to infection control (p = 0.0001). There was no significant association with respect to sex, age and public or private schools.

CONCLUSIONS:: Educational procedures should be conducted in relation to infection control protocols in oral radiology, especially among male dentists, regardless clinic specialty, and among the students of the last year of the dental school.
