Role of Pharmacology in Dentistry: A Review of Analgesics, Antibiotics, and Local Anesthetics.

This review explores the essential role of pharmacology in dentistry, emphasizing the use of analgesics, antibiotics, and local anesthetics in managing pain, controlling infections, and ensuring procedural comfort. The integration of these pharmacological agents has significantly advanced dental care, allowing for more effective and patient-friendly treatments. Nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen serve as the primary analgesics, while opioids, despite their efficacy in severe cases, require careful prescribing due to their high risk of dependency and adverse effects. Antibiotics are indispensable for treating odontogenic infections and preventing systemic complications, yet their overuse has contributed to the global challenge of antimicrobial resistance, necessitating stringent antibiotic stewardship in dental practice. Local anesthetics, particularly lidocaine and articaine, have revolutionized pain-free dentistry, with advancements such as liposomal formulations, buffered anesthetics, and computer-assisted anesthesia enhancing their effectiveness and safety. Despite these innovations, challenges such as opioid dependency, antibiotic resistance, and individual variability in anesthetic response underscore the need for personalized pharmacotherapy. Emerging research in pharmacogenomics and novel drug delivery systems holds promise for optimizing treatment outcomes by tailoring pharmacological interventions to individual patient profiles. Future directions should focus on integrating precision medicine, improving antimicrobial strategies, and developing safer, more efficient anesthetic techniques. By incorporating evidence-based prescribing practices and adopting innovative pharmacological approaches, dentistry can continue to evolve toward safer, more effective, and patient-centered care.
