Anesthesia · single question
Which local anesthetic technique is best avoided in a pediatric patient with primary teeth?
Show answer and explanation
Correct answer: D. Intraligamentary (PDL) injection
- A. Topical anesthetic is used before every injection in children and is not contraindicated.
- B. Infiltration is the routine, safest technique in children because of thin, porous alveolar bone.
- C. IANB is standard for mandibular primary molars — used cautiously but not contraindicated.
- D. Correct. High-pressure PDL injection over a primary tooth can damage the underlying developing permanent tooth germ, producing enamel hypoplasia or hypomineralization.
