The purpose of the Research Study and Overview of Participation: This study will compare different approaches used to prevent pain when giving local anesthesia to numb the teeth while managing dental cavities and decay. Specifically, it seeks to determine which approach will reduce the pain and discomfort during or after the procedure. This will help dentists to choose the best approach to reduce patient's pain and discomfort and improve the overall experience of dental treatment. Participants in the study would likely undergo the following: 1. Screening and Consent: Participants would be assessed for eligibility (e.g., age, health status, and presence of dental caries requiring treatment) and would provide informed consent. 2. Intervention: Participants would be randomly assigned to different groups based on the type or method of topical anesthesia being tested. 3. Treatment Procedure: Dental caries management would be performed under local anesthesia, with the designated topical anesthetic applied beforehand. 4. Pain Assessment: Participants would rate their pain levels during and after the procedure using validated pain measurement scales (e.g., visual analog scale). 5. Follow-Up: Participants might be monitored for a short duration post-treatment to assess any residual pain or side effects. This design ensures that the study collects reliable data on the effectiveness of the different topical anesthetic approaches while prioritizing patient safety and comfort.

Photobiomodulation (PBM)-induced analgesia device using multi-wavelength LED
Topical anesthesia (Benzocaine 20%)
Placebo with no intervention.
Pain score after local anesthesia administration, dental procedure, and 48 hours postoperatively.
Pain score based on Visual Analog Scale (1-10) with highest score indicates the most severe pain.
Time frame: Within 5 minutes after local anesthesia administration, during dental procedure, directly after finishing the procedure, and 48 hours postoperatively.
Pain score with prick pain test (PPT)
Pain score will be reported as "pain" or "no pain".
Time frame: One minute after topical anesthesia.
Pain score with pulpal stimulation using electric pulp tester (EPT)
Digital reading from 1 to 64 with the highest score indicates no pain response on electric stimulation.
Time frame: After 2 minutes of topical anesthesia.
Amount of local anesthesia to be given
Counting the number of used local anesthetic carpules.
Time frame: At the end of dental procedure.
Need for additional analgesics
Count the number and dose of oral analgesics taken by the patient.
Time frame: Within 48 hours postoperatively.
Reporting of any adverse effects, such as mucosal irritation, allergic reactions, and delayed pain relief.
Reported by the patient.
Time frame: Within 48 hours postoperatively.
