About this study

Official title: 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Dental anesthesiaBehavioural

    The intervention consists of pre-cooling and/or a sweet-tasting solution, used alone or in combination with topical local anesthesia, before administration of the dental local anesthetic injection.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Visual Analog Scale (VAS)

    Pain Intensity assessed by visual analogue scale

    Measured: Immediately after intervention

Secondary outcomes (4)
  1. Phase 1 outcome

    The preferred sweet tasting solution based on number of patients

    Measured: After intervention

  2. Heart Rate

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

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

  3. Sound, eye and motor scale (SEM) scale

    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.

    Measured: During needle injection

  4. Oxygen saturation

    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.

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

Questions about this trial

What is this clinical trial studying?

A study testing Dental anesthesia in people with Dental Anesthesia and Sweet Taste Perception, run by British University In Egypt at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 22 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visual Analog Scale (VAS) (time frame: Immediately after intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Sep 2026.
