Knowledge of antibiotics and antimicrobial resistance amongst final year dental students of Polish medical schools-A cross-sectional study.

INTRODUCTION: Antimicrobial resistance has been one of the biggest global concerns. Dentists constitute an important group of antibiotic prescribers, and it was shown that their therapeutic decisions are not always rational. In this paper, we present knowledge of antibiotics prescription rules and antimicrobial resistance amongst graduating dentistry students from all dentistry faculties of medical universities in Poland, who will soon join the group of antibiotics prescribers.

MATERIALS AND METHODS: A questionnaire consisting of 28 questions was developed. The survey was conducted in May-June 2015.

RESULTS: The study group comprised a total of 752 students. About 54% expressed the opinion that dentists overprescribe antibiotics. One-tenth thought that they can be used for the treatment of flu (7%) and common cold (11%). Respondents pointed to amoxicillin (46%) and clindamycin (44%) as the first-choice treatment of dentoalveolar abscess, if medically indicated. More than half of the students (58%) suggested using doxycycline and metronidazole in aggressive periodontitis in an individual allergic to penicillin. The vast majority of students (97%) indicated that penicillins and cephalosporins were suitable for treatment of dental infections in pregnant women. The majority of participants (82%) said that rheumatic disease, chronic immunosuppression, chronic kidney failure and a history of infective endocarditis required a prophylactic administration of antibiotics before or during endodontic treatment.

CONCLUSIONS: The research showed variable levels of understanding of antibiotics use amongst dental students in medical universities in Poland. Our results emphasise the need to educate dental students further regarding antibiotics and risks related to antibiotic misuse, especially in dental practice.
