Study summary

This study aims to compare the effects of computer-controlled local anesthesia and conventional inferior alveolar nerve block on dental anxiety and pain in children undergoing pulpectomy of mandibular primary molars. Both anesthesia techniques are routinely used in pediatric dental practice and are considered standard methods of care.

Children aged 6 to 8 years who require bilateral pulpectomy of mandibular primary molars will be included in this split-mouth randomized clinical trial. Each participant will receive both anesthesia techniques during separate treatment sessions. Dental anxiety, pain, and physiological parameters, including heart rate, blood pressure, oxygen saturation, and body temperature, will be assessed before, during, and after treatment using validated pediatric assessment scales and routine clinical measurements.

The findings of this study may help identify the anesthesia technique that provides greater comfort and reduces anxiety and pain during pediatric dental treatment, thereby improving the overall treatment experience for children.

  • No previous experience with dental local anesthesia.
  • No signs of acute abscess or swelling in the treatment area.
  • Parent or legal guardian able to provide written and child willing to participate.

Exclusion criteria

Exclusion Criteria:

  • ASA Physical Status II or higher.
  • Known allergy or to local anesthetic agents.
  • Frankl Behavior Rating Scale score of 1 or 2.
  • Children receiving psychological or psychiatric treatment.
  • Physical or intellectual disabilities that could interfere with study procedures.

  • Presence of acute abscess, cellulitis, or diffuse swelling in the treatment area.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Dental Anxiety

    Dental anxiety assessed using the Modified Child Dental Anxiety Scale-faces version (MCDASf). Higher scores indicate higher levels of dental anxiety.

    Time frame: Baseline and immediately after treatment

  2. Behavioral Pain During Local Anesthesia

    Behavioral pain assessed using the Face, Legs, Activity, Cry, Consolability (FLACC) scale during local anesthesia administration. Scores range from 0 to 10, with higher scores indicating greater pain.

    Time frame: Immediately after local anesthetic injection

Secondary outcomes

  1. Self-reported Pain

    Pain assessed using the Wong-Baker FACES Pain Rating Scale immediately after treatment. Self-reported pain assessed using the Wong-Baker FACES Pain Rating Scale (0-10) immediately after completion of pulpectomy. Scores range from 0 to 10, with higher scores indicating greater pain intensity.

    Time frame: Immediately after local anesthetic injection

  2. Facial Image Scale (FIS) Score

    Emotional status assessed using the Facial Image Scale (FIS). Higher scores indicate greater anxiety. Emotional status assessed using the Facial Image Scale (FIS). The scale ranges from 1 to 5, with 1 indicating no anxiety (very happy face) and 5 indicating severe anxiety (very unhappy face). Higher scores indicate greater anxiety.

    Time frame: Baseline and immediately after treatment.

  3. Heart Rate

    Heart rate measured using a pulse oximeter.

    Time frame: Baseline and during local anesthetic administration

  4. Blood Pressure

    Systolic and diastolic blood pressure measured with an automated monitor.

    Time frame: Baseline, during local anesthetic administration, and immediately after treatment

  5. Peripheral Oxygen Saturation (SpO₂)

    Peripheral oxygen saturation measured using pulse oximetry.

    Time frame: Baseline, during local anesthetic administration, and immediately after treatment

  6. Body Temperature

    Body temperature measured using a digital thermometer.

    Time frame: Baseline, during local anesthetic administration, and immediately after treatment

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Aug 2026; primary completion for Aug 2026, 0 months later.

Of 3,731 non-industry interventional studies with no phase under Pain, half reached primary completion within 10 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 23. This study's planned 0 months is below that.

Counting every sponsor, half of 3,830 studies reached it within 10 months; a quarter within 4 and three quarters within 23.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 12, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
