Local Anesthesia Pen vs Conventional Syringe in The Treatment of Pain and Dental Anxiety: A Randomized Controlled Trial

The goal of this is to compare pain and anxiety that may occur during dental anesthesia delivery using conventional dental syringe and the dental anesthesia injector (wireless pain less pen in pediatric dentistry. This is a cross-over randomized clinical trial is to investigate if one technique more efficiant in reducing pain and anaxity. This study could include medically healthy children between the age 6-12 years old requiring restorative dental work. The main question aims to answer [is/are]: Is new painless injector pen better or equal to convintional syrange in reducing both pain and anaxity? Randomization will be generated. Children will recive the first dental treatment under eaither systems then a washout period of 14 days will be carries out, then the same patient will recive the dental treatment on the other side using the 2nd device acording to the manufactuurer instructions.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain Score
Time Frame: Baseline and immediate post-procedure
Wong-Baker FACES Pain Rating Scale, is a self-report measure consisting of a series of six facial expressions (FACES) representing increasing levels of pain. Scores range from 0 to 10, with 0 (happy face) indicating "no hurt" and 10 ( a crying face) indicating "hurts worst". Higher scores represent greater pain intensity and therefore a worse outcome.
Baseline and immediate post-procedure
Anxiety using the Modified Dental Anxiety Scale (MDAS)
Time Frame: Baseline and immediate post- procedure
The Modified Dental Anxiety Scale is a self-reported measure of dental anxiety consisting of five items, each scored on a 5-point Likert scale. Total scores range from 5 to 25, with 5 indicating no dental anxiety and 25 indicating extreme dental anxiety. Higher scores represent greater dental anxiety and therefore a worse outcome.
Baseline and immediate post- procedure
