A 4-year-old boy with muscular dystrophy needs pulp treatment of the lower second primary molar. What anesthesia is appropriate?
Show answer and explanation
Correct answer: A. Intraligamentary injection
- A. Correct. For pulp treatment of a mandibular primary molar in a 4-year-old, the IAN block is appropriate. Muscular dystrophy does not contraindicate standard regional anesthesia.
- B. Incorrect. Intraligamentary (PDL) injection is contraindicated in children as it may damage the underlying permanent tooth bud.
- C. Incorrect. Infiltration alone provides insufficient anesthesia depth for mandibular primary molar pulp treatment.
- D. Incorrect. Topical alone is entirely insufficient for pulp therapy.
