Bleeding from the oral mucosa can be reduced by topical use of_______________?
Correct answer: A. Epinephrine
- A. Epinephrine
- B. Lidnocaine
- C. Hydrocortisone
- D. Dicoumarol
Explanation
Topical epinephrine causes local vasoconstriction through alpha-adrenoceptor stimulation, reducing blood flow and helping control oral mucosal bleeding. Lidocaine provides local anaesthesia but does not reliably stop bleeding unless combined with a vasoconstrictor.
