Recruiting at 1 site in Egypt. Open to participants aged 5 Years to 12 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-11-04.
Sponsored by National Research Centre, Egypt · Not applicable, Interventional, and Supportive care
22 children with two primary molars that need extraction or pulpotomy will be selected to compare pain perception between conventional dental syringe and cordless electronic local anesthetic delivery system.
This is a split mouth randomized controlled trial, will be conducted in the outpatient clinic of pediatric dentistry, Medical and scientific Centre of Excellence, National Research Centre. and who have two primary molars that are indicated for pulpotomies or extractions. The study's protocol, risks, and benefits will be explained to the parents or legal guardians, and informed consent will be obtained from them if they agree to participate.

Device: Cordless Electronic local anesthetic delivery system
Device: Conventional dental syringe
Wireless computer-controlled local anesthetic delivery (CCLADs) (Star Pen)with the control unit integrated into the syringe body, eliminating the need for foot pedal attachments. it uses use conventional dental needles and LA carpules
The injection of a local anesthetic using conventional dental syringe
Pain perception
assessment of pain perception between the two devices using Wong-Baker FACES Pain Rating Scale (WBFPRS), it consists of 6 faces with word descriptors and numbers from 0 to 10. The child is asked to point to the face that describes how he/she feels at the particular moment and numbers on this scale can be adjusted to a 0 to 10 Also FLACC Scale (Face, Legs, Activity, Cry, and Consolability) is used to assess behavioral pain of the child, it has scores from 0 to 2.
Time frame: perioperative
Dental fear and anxiety
correlation between dental fear and anxiety and pain perception using Dental Subscale of Children's Fear Survey Schedule (CFSS-DS)
Time frame: perioperative
