Knowledge and Misconceptions About Antibiotic Use and Resistance Among Dental Clinic Visitors in Saudi Arabia-A...

Background/Objectives: Antibiotic resistance (AR) is a major public health concern, mainly driven by the misuse of antibiotics. Dental settings are one area where unnecessary antibiotic prescriptions and misconceptions among dental patients contribute significantly to antibiotic misuse. This study aimed to evaluate the knowledge and understanding of antibiotic use and AR among dental clinic visitors in Saudi Arabia. Methods: A cross-sectional survey was conducted between March and June 2024, targeting males and females aged 18 years and older residing in Saudi Arabia who visited a dental clinic within the past five years. A self-administered questionnaire was used to assess participants' knowledge of antibiotic use and their awareness of AR. Results: A total of 1455 respondents from different regions of Saudi Arabia completed the survey. The majority of participants (70.1%) correctly identified that antibiotics kill bacteria, but around 30% incorrectly believed antibiotics treat viral infections. Additionally, 19.58% thought it was acceptable to stop taking antibiotics once they feel better. More than half of the participants thought that antibiotics reduce inflammation (69.10%) or relieve pain (52.40%). Nearly half of the participants (48.45%) were unaware of the term "antibiotic resistance (AR)," and only 27.2% identified antibiotic overuse as a cause of AR. A significant association was found between undergoing dental procedures and perceiving antibiotics as necessary (p < 0.0001). Educational level was the only significant predictor of AR awareness (AOR = 2.942; p < 0.0001). Conclusions: Although many participants correctly answered a knowledge question about antibiotics killing bacteria, several misconceptions about antibiotic use and a lack of awareness regarding AR were identified. These findings highlight the need for targeted educational interventions and enhanced antibiotic stewardship in dental practice to control AR.
