Clinical Success of 12 mm Needle IANB in Children

Prospective Single-Arm Pilot Study of Clinical Success and Safety of Inferior Alveolar Nerve Block Using a 12 mm 30-Gauge Extra-Short Needle in Children Aged 4-12 Years

This prospective single-arm pilot study will evaluate the clinical success of an inferior alveolar nerve block performed using a 12 mm 30-gauge extra-short dental needle in children aged 4 to 12 years. The study will assess whether this needle length can provide effective local anesthesia for dental treatment in children while minimizing potential complications associated with greater needle penetration. The study will also document any adverse events or complications related to the injection technique
