Course Introduction
Dental Pharmacology Final
Exam Questions
Dental Pharmacology explores the principles and applications of pharmacological agents relevant to dental practice. The course covers drug classifications, mechanisms of action, pharmacokinetics, and pharmacodynamics of medications commonly prescribed in dentistry, such as local anesthetics, antibiotics, analgesics, and anti-inflammatory drugs. Emphasis is placed on drug interactions, contraindications, and side effects, as well as the management of medical emergencies related to pharmacological agents in dental settings. Students will gain the foundational knowledge necessary to safely and effectively select and administer medications, taking into consideration patient-specific factors and current best practices.
