Antibiotic Prescription in Dentistry: Trends, Patient Demographics, and Drug Preferences in Germany.

ABs are widely used in dental practice in the treatment of odontogenic infections and as systemic prophylaxis in high-risk patients. However, AB overuse contributes to antimicrobial resistance (AMR), which is a major global concern. This study examined dental AB prescribing trends in Germany in 2024, focusing on the share of overall AB prescriptions, patient demographics, and commonly used agents. This retrospective cross-sectional study used data from the IQVIA Longitudinal Prescription Database (LRx), covering approximately 80% of prescriptions reimbursed by statutory health insurance funds in Germany. Patients with at least one AB prescription (ATC code: J01) issued by a dentist in 2024 were analyzed. Descriptive statistics covered age, sex, and prescribed substances. In 2024, German dentists prescribed ABs to 2,325,500 patients, accounting for 13.9% of all patients in the database who received AB prescriptions. Dentists were the second-largest group of AB prescribers, surpassed only by general physicians. Amoxicillin (54.2%) was most frequently prescribed, followed by amoxicillin with clavulanic acid (24.5%) and clindamycin (21.0%). Dental patients receiving AB prescriptions were older (mean age: 49.8 years) than the general antibiotic patient population (44.7 years). Interestingly, dental AB prescriptions increased during the COVID-19 pandemic, in contrast to the sharp overall decline in AB prescriptions. Between 2015 and 2019, the proportion of dental antibiotic prescriptions showed a moderate upward tendency, followed by a marked increase during the COVID-19 pandemic and a subsequent decline. In contrast, the number of patients receiving antibiotic prescriptions from other medical disciplines decreased over the same period. One particularly notable finding was the extended use of clindamycin, a reserve AB with known side effects and resistance risks, in dentistry. Dentists are responsible for a significant share of AB prescriptions in Germany. The rise in dental AB prescriptions, particularly the frequent prescription of clindamycin, underscores the need for interventions such as updated clinical guidelines and awareness campaigns concerning AB-related risks and their mitigation directed at dentists. These could focus on microbial culture and sensitivity testing and patient adherence education and control for targeted AB interventions. Emphasizing preventive and alternative anti-infective treatment strategies in dentistry may also help to contain AMR.
