How is the study designed?

Design Details

  • Primary Purpose: Supportive Care
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Group A
Other: BrightHearts"biofeedback relaxation tool

Before the inferior alveolar nerve block procedure, Participants will be taught to use the application after given instructions.

They will be asked to keep a constant color by focusing on breathing slowly, then they will be allowed to use the application a few minutes before the inferior alveolar nerve block procedure
Active Comparator: Group B
Device: Virtual Reality distraction
participants in this group will experience Virtual Reality distraction eyewear. After giving an introduction about it, they will be allowed to accommodate, then they will be wearing it during the inferior alveolar nerve block procedure in an environment designed to distract them during the injection. The Virtual Reality distraction content will be age-appropriate and engaging, and feature interactive (e.g., Fun animations, and Cartoons).
Active Comparator: Group C
Behavioral: Verbal distraction technique

The Verbal distraction method technique involves:

patient is given an instruction to do in order to divert his/her attention

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Evaluation of Dental Anxiety.
Time Frame: - Baseline (5 minutes before injection) - During injection - 2 minutes after injection
Using Heart rate monitor. Heart Rate (beats per minute [bpm]) measured using a heart rate monitor. Higher heart rate values indicate greater physiological anxiety.
- Baseline (5 minutes before injection) - During injection - 2 minutes after injection

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Evaluation of Dental Anxiety
Time Frame: Baseline (5 minutes before injection)and immediately after injection.
Using Facial Image Scale scores range from 1 to 5, with 1 indicating no anxiety (very happy face) and 5 indicating highest anxiety (very unhappy face). Higher scores indicate greater dental anxiety.
Baseline (5 minutes before injection)and immediately after injection.
Behavior Assessment
Time Frame: During injection
FLACC Rating Scale. Face, Legs, Activity, Cry, Consolability (FLACC) Scale. Scores range from 0 to 10, with higher scores indicating greater pain and distress.
During injection
