Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this single-blinded randomized controlled trial is to compare pain perception during buccal infiltration using indirect EC spray and topical anesthesia and BC 20% topical gel, among seven to 10-year-old school children who attended Pediatric Dentistry Department at Dubai Dental Hospital (DDH), Mohammed Bin Rashid University (MBRU) in Dubai, the United Arab Emirates (UAE).

The main question\[s\] it aims to answer are:

• How effective is the indirect application of EC topical spray anesthesia on pain perception during intraoral buccal injection in children in comparsion to BC 20%?

Researchers will compare efficacy of 20% Benzocaine (BC) gel and indirect application of Ethyl Chloride (EC) spray to see if reducing pain perception during local anesthesia infiltration.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Pre-local analgesia topical Benzocaine gel or Ethyl Chloride technique will be selected randomly and applied per the protocol. A single calibrated operator (A.A) using randomly selected sealed envelopes that have been previously divided equally according to sample size arms. The selected envelope is then opened by the operator, who applies either the EC or BC topical anesthesia technique based on the chosen envelop. Followed by maxillary local analgesia buccal infiltration for a single tooth by a calibrated operator (A.A). The child is then observed and assessed by the blinded primary investigator (N.A) (to the topical anesthesia technique) for pain perception during local anesthesia infiltration based on the Sound, Eye, Motor index used in this study. The child is then asked to rate the Visual Analog Scale and Facial Pain Scale. Heart rate of the patient will be recorded as per below protocol.
