Intraligamentary anesthesia technique — what can it CAUSE after the procedure?
Show answer and explanation
Correct answer: B. Post-injection pain
Post-injection pain (B) is the most common complication of intraligamentary (periodontal ligament) injection. The technique involves injecting anesthetic under high pressure directly into the PDL space, which can cause:
• Post-injection pain/soreness at the injection site due to pressure ischemia of the PDL and alveolar bone.
• Transient periodontal discomfort lasting hours to days.
• Risk of damage to the PDL and alveolar bone if over-pressure is applied (especially in developing teeth).
• Bleeding (A): minimal with intraligamentary injections — the PDL space is tight.
• This technique is useful for isolated single-tooth anesthesia, supplemental to failed inferior alveolar nerve block, and in primary teeth. It is NOT recommended for permanent teeth in children due to potential effects on the developing succedaneous tooth.
