Which of the following is NOT a common side effect of local anesthetics used in dentistry?
Show answer and explanation
Correct answer: C. Bradycardia
- A. Paresthesia (usually lingual or inferior alveolar, most associated with 4% articaine and prilocaine) is a recognized complication.
- B. Dizziness/lightheadedness is common, especially with intravascular uptake or anxiety.
- C. Correct (NOT common). BRADYCARDIA is not a typical local anesthetic side effect. In dental practice the far more common cardiovascular response is TACHYCARDIA and palpitations, driven by the EPINEPHRINE vasoconstrictor or by endogenous catecholamine release from anxiety. Bradycardia in the chair is more characteristic of vasovagal syncope.
- D. Nausea can occur, particularly with systemic absorption or in an anxious patient.
