Which type of local anesthetic injection is used to anesthetize the pulpal tissue of mandibular posterior teeth?
Answer: Inferior alveolar nerve block
The inferior alveolar nerve block (IANB) anesthetizes the inferior alveolar nerve, providing pulpal anesthesia to mandibular teeth on the injected side.
An EFDA notices a patient's heart rate has significantly increased after a local anesthetic injection. This is most likely due to:
Answer: Intravascular injection of epinephrine
Accidental intravascular injection of epinephrine can cause a sudden increase in heart rate (tachycardia) and blood pressure.
Which medication class is commonly prescribed to reduce anxiety before dental procedures?
Answer: Benzodiazepines
Benzodiazepines such as triazolam or diazepam are used for oral conscious sedation to reduce preoperative dental anxiety.
What is the drug of first choice for treating an anaphylactic reaction in a dental office?
Answer: Epinephrine (1:1,000)
Epinephrine 1:1,000 administered intramuscularly is the first-line emergency treatment for anaphylaxis due to its rapid bronchodilation and vasopressor effects.
Which antibiotic is the drug of choice for prophylaxis before dental procedures in patients at risk for infective endocarditis?
Answer: Amoxicillin
Amoxicillin 2 g orally one hour before the procedure is the current AHA-recommended prophylaxis for at-risk cardiac patients.
Which dental drug interaction requires the EFDA to alert the dentist before administering a local anesthetic with epinephrine?
Answer: Patient takes non-selective beta-blockers
Non-selective beta-blockers can potentiate the vasopressor effect of epinephrine, causing a significant hypertensive episode.
