About this study

Official title: The Efficiacy Of Dental Electronic Syringe In Reducing Disconfort During Local Infiltration Anesthesia

The goal of this clinical study is to compare patients' self-reported pain and mental stress during infiltration anesthesia between conventional syringe and Dentapen.

Outcome 1: VAS score of self-reported pain during dental anesthesia Outcome 2: Heart rate variability during dental anesthesia

Being tested
computer controlled local anesthesia delivery device (Dentapen), Control
Keywords
heart rate variability, CCLAD, dental anesthesia

What participants receive

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

  • computer controlled local anesthesia delivery device (Dentapen)Device

    The participants were delivered local anesthesia using a computer-controlled local anesthesia delivery (CCLAD) device.

  • ControlDevice

    Conventional syrine was used to administer local anesthesia. Participants in this group would received manual anesthesia.

What is being measured

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

  1. Heart rate variability

    Heart rate variability (HRV) is is the precise measure of the variation in time (milliseconds) between consecutive heartbeats. HRV is measured using a device around patient chest.

    Measured: From enrollment to the end of tooth extraction treatment at 4 weeks. Each patient experienced two extraction treatments with 4-week interval.

  2. Self-reported pain

    Patients reported how much pain intensity that they feel during dental anesthesia by using a visual analogue scale. Scale value ranges from 0 (no pain) to 100 (maximum pain).

    Measured: Patients reported right after dental anesthesia delivery.

Questions about this trial

What is this clinical trial studying?

A study of Healthy Participants and Tooth Extraction, run by Son Hoang Le at 1 site in Vietnam.

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 5 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: finished, as of the sponsor's last update on 25 Feb 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 Vietnam. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Heart rate variability (time frame: From enrollment to the end of tooth extraction treatment at 4 weeks. Each patient experienced two extraction treatments with 4-week interval.). The study lists 2 primary outcomes in all. 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 25 Feb 2026.
