Background and Objectives: Inappropriate antimicrobial prescribing is highly reported in dentistry. The objective of the study was to see the effect of dental qualification and practice settings on antimicrobial prescribing practices among dental practitioners in Delhi and National Capital Region (NCR) of India. Materials and Methods: A self-designed and pretested questionnaire was given to 667 dental practitioners holding degrees of graduation, postgraduation, and those pursuing postgraduation, working in academic institutions and private clinics in NCR of India. Data were analyzed using statistical software Stata version 12.0. Chi-square and logistic regression tests were used for analysis. Results: Out of total 539 responded, 66.4% of the practitioners prescribed by brand name and 27.8% by generic name. Amoxicillin * clavulanic acid (27.4%) was the first choice. Only 26% of the practitioners asked for antimicrobial susceptibility testing. Space infections (91.9%), impacted third molar extractions (89.7%), and periodontal abscess (88.1%) were the conditions where antimicrobials were most frequently prescribed. However, 60.9% and 53.3% of the practitioners also prescribed antimicrobials for acute pulpitis and dry socket, respectively. For prophylaxis in medical conditions, amoxicillin was the first choice. In case of history of allergy to penicillin, 52.3% of the practitioners prescribe erythromycin whereas 14.6% prescribe amoxicillin. The adverse drug reporting culture was negligible, and only 14.3% of the practitioners were aware of the Pharmacovigilance Program of India. Level of qualification had a significant effect on prescribing (P < 0.05). Interpretation and Conclusion: Frequent irrational prescribing of antimicrobials used in odontogenic conditions warrants an urgent and continued need for guidelines as well as educational intervention programs in dentistry. This will improve the quality of antimicrobial prescribing practices in dentistry.
