Introduction to the theory of pharmacology as it relates to dentistry. Includes drug action and handling, prescription writing, autonomic drugs, non-opioid analgesics, anti-infective agents, anti-fungal and anti-viral agents, anti-anxiety agents, cardiovascular agents, and anti-convulsant agents. Also includes psychotherapeutic agents, antacids and antihistamines, adreno cortico steroid agents, anti-neoplastic agents, and respiratory and gastrointestinal medications, emergency medications, and drug interactions and drug abuse.

Information: Students must be admitted to the PCC Dental Hygiene program and obtain consent of the Dental Hygiene department before enrolling in this course.

Course Learning Outcomes
  1. Demonstrate foundational knowledge of drug classifications and regulatory requirements.
  2. Evaluate the pharmacological management of pain, anxiety and infection in dental care.
  3. Assess drug interactions, adverse reactions and contraindications relevant to dental hygiene practice.
  4. Describe the mechanisms and therapeutic roles of cardiovascular, respiratory and endocrine medications.
  5. Explain the dental implications of psychotherapeutic, anticonvulsant and immunosuppressive agents.

Performance Objectives:
  1. Apply knowledge of pharmacology terminology, dosage calculations, measurement units, and safety measures to accurately write and assess dental prescriptions, especially in cases involving pediatric and pregnant patients.
  2. Analyze drug labels, including black box warnings, and understand regulatory classifications to ensure safe medication use and patient education.
  3.  Evaluate the effects of different administration routes on drug bioavailability, efficacy, and patient outcomes.
  4. Describe how drugs interact within the body and with each other, understanding the implications of bioequivalence, adverse reactions, and interactions on dental treatment plans.
  5. Assess the appropriate use of non-narcotic analgesics and NSAIDs, understanding their mechanism of action and potential side effects in dental settings.
  6. Understand the role, limitations, and risks of opioid analgesics in dental care, emphasizing the importance of monitoring for dependency and substance abuse.
  7. Distinguish between bactericidal and bacteriostatic antibiotics, and assess the appropriateness of topical and systemic antibacterial agents in dental infection control.
  8. Describe the advantages and considerations of using controlled-release antimicrobial agents in periodontal therapy.
  9. Explain the pharmacological treatment options for common dental infections, such as herpes simplex, and understand the roles of antifungal and antiviral agents.
  10. Understand the use of benzodiazepines, barbiturates, and nitrous oxide, analyzing their benefits and risks in managing dental anxiety and procedural sedation.
  11. Apply knowledge of antihypertensives, anti-angina drugs, and anti-arrhythmics to ensure safe and effective dental care for patients with cardiovascular conditions.
  12. Recognize the dental considerations and adverse effects of anticonvulsant medications in patients with seizure disorders.
  13. Identify the effects of antipsychotics, mood stabilizers, and anxiolytics on dental health, including any dental side effects that may impact treatment.
  14. Understand the systemic effects and dental treatment considerations for patients using corticosteroid medications.
  15. Evaluate the implications of chemotherapy and immunosuppressive therapy for dental treatment, recognizing side effects and necessary precautions.
  16. Explain the dental considerations for patients taking medications for asthma, colds, coughs, peptic ulcers, and other respiratory or gastrointestinal conditions.
