Outcome Measures

Primary Outcomes (2)

  • 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.

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

  • 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).

    Patients reported right after dental anesthesia delivery.

Study Arms (2)

Dentapen

EXPERIMENTAL

On the experimental side, researcher used Dentapen, a Computer-Controlled Local Anaesthetic Delivery device, to deliver anesthesia for patients.

Device: computer controlled local anesthesia delivery device (Dentapen)

Control

ACTIVE COMPARATOR

This arm was admistered local anesthesia with conventional syringe

Device: Control

Interventions

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

Dentapen
ControlDEVICE

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