Pain and Anxiety in Pediatric Dentistry: Computer-Controlled vs. Traditional Anesthesia

For both maxillary and mandibular teeth, 1.7 mL of Ultracaine D-S Fort carpule (4% articaine with 1:200,000 epinephrine) was administered in two stages (gingival and intraosseous injection) using a computer-controlled intraosseous anesthesia system with a 30-gauge, 9 mm Effitec needle.

For maxillary teeth, buccal infiltration is performed using a metal carpule syringe and a 30G, 16 mm Effitec needle (Dental Hi Tec, France); after aspiration, Ultracaine D-S Fort is slowly injected over 1 minute.

For mandibular teeth, the injection site is dried, and a 27G, 35 mm Effitec needle (Dental Hi Tec, France) is inserted between the pterygomandibular raphe and internal oblique ridge, aligned with contralateral molars. After aspiration, Ultracaine D-S Fort is slowly injected over 1 minute using a traditional metal carpule syringe, following the standard mandibular block technique.
