Efficacy of Pre-cooling and Sweet-tasting Solution on Pain Related to Local Anesthesia Injection in Children

16. september 2026 oppdatert av: Nada Mohammed Farouk, British University In Egypt

Efficacy of Pre-cooling and Sweet-tasting Solution on Pain Related to Local Anesthesia Injection in Children: A Randomized Control Trial

The study aims to determine whether pre-cooling and sweet-tasting solutions, alone or combined with topical anesthesia, provide better pain control during dental local anesthesia in children.

It has two phases:

Phase 1: Identify the children's preferred sweet-tasting solution among xylitol, monk fruit, erythritol, and honey.

Phase 2: A randomized controlled trial comparing 7 groups involving pre-cooling, sweet solution, topical anesthesia, and their combinations.

The primary outcome is pain measured by VAS, while secondary outcomes include SEM behavioral response, heart rate, and oxygen saturation. The planned sample is 220 children.

Heart Rate
Tidsramme: Heart rate (beats per minute) measured immediately before needle insertion (baseline) and during needle injection and after needle injection

Heart rate (beats per minute) measured immediately before needle insertion (baseline) and the maximum heart rate recorded during needle injection and after needle injection

Heart rate (beats per minute) measured immediately before needle insertion (baseline) and during needle injection and after needle injection
Sound, eye and motor scale (SEM) scale
Tidsramme: During needle injection

Behavioral pain response during local anesthetic injection assessed using the Sound, Eye, and Motor (SEM) Scale. Sound, eye, and motor responses are each scored from 1 to 4, with 1 indicating comfort and 4 indicating a painful response. The three component scores are summed to obtain a total SEM score ranging from 3 to 12, with higher scores indicating greater behavioral response to pain.

During needle injection
Oxygen saturation
Tidsramme: Immediately before needle injection (baseline), during needle injection, and immediately after completion of injection. Recorded as percentage

Peripheral oxygen saturation (SpO₂) will be measured using a pulse oximeter and recorded as a percentage at three time points: immediately before local anesthetic needle injection (baseline), during needle injection, and immediately after completion of the injection.

Immediately before needle injection (baseline), during needle injection, and immediately after completion of injection. Recorded as percentage
