[Attitudes and habits for the control of HIV and hepatitis B in dental students].
HIV infection has had great impact on dental practice, mainly because public and professional perceptions about HIV-AIDS contagion are conflictive due to fear and ignorance. Since the practices of infection control have not been adequately studied in Mexico, the present survey explored some attitudes towards HIV infection, stated knowledge on HIV transmission and manifestations, and infection control procedures reportedly used by dental students. A questionnaire was administered to 262 final-year students (95% were 20 to 30 years old; 71% female) in Mexico City (July-August 1992), with emphasis on the clinical risk posed by HIV and hepatitis B (HBV) infections. Data were analyzed with Student's t-test and one-way ANOVA (Scheffé test). Results showed a mixed response as a general rule, with most respondents believing they had a moral (83%) and professional (78%) duty to treat HIV+ patients but few having a sympathetic approach to them. Only a minority have had a direct experience with HIV+ patients (5%) or high-risk groups (24%). Students seemed to use adequate infection control barriers as most wore gloves, gowns, masks and glasses while treating patients, but only 20 per cent had been vaccinated against hepatitis. Some contradictions in the use of disinfecting/sterilization equipment and agents were detected. The most important reasons given to refuse to treat HIV+ patients were the lack of appropriate facilities and the risk of becoming infected. The sources of information on HIV most frequently resorted to were reported to be professional education and short courses of continuing education.
