Study notes
A 25-year-old patient presents with a deep cavity in the lower right second molar (tooth 47). Diagnosis: Reversible pulpitis. Treatment: 1. Apply topical gel (Benzocaine) to the injection site for 60 seconds to numb the surface. 2. Perform an IANB using 1.8ml of 2% Lidocaine with 1:80,000 Epinephrine. 3. Advance the 27-gauge long needle until it contacts the ramus of the mandible. 4. Withdraw slightly, aspirate, and slowly deposit anesthetic over 60 seconds. 5. Confirm numbness of the lower lip after 5 minutes. Outcome: The tooth is successfully isolated and prepared without pain. Follow-up: Patient advised to avoid chewing on the lip until the numbness wears off to prevent accidental biting.
