June 26, 2026 updated by: Jaya chandra Reddy Bhumireddy, Government Dental College and Hospital, India

Efficacy of a Vibrating Facial-T- Massager as an Adjunct to Topical Anesthesia in Reducing Intraoral Injection Pain in Children: A Randomized Controlled Trial.

Abstract

  • Background: Local anesthesia is a primary source of anxiety in pediatric dentistry.
  • Objective: To evaluate if mechanical vibration from a low-cost facial massager reduces pain and anxiety during injections using the Gate Control Theory.
  • Design: Prospective Randomized Controlled Trial .

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Methodology & Study Design

  • Setting: Pediatric Dental Department, Kadapa, Andhra Pradesh.
  • Inclusion Criteria: Children aged 4-12 years requiring local anesthesia, cooperative (frankl 3,4)
  • Exclusion Criteria: History of allergy to benzocaine, acute infection at the site, or special healthcare needs affecting sensory perception, Medically compromised, unco-operative children, those who do not consent.

Intervention Protocol

  1. Group 1: Application of 20% Benzocaine gel for 2 minutes followed by a standard local anesthetic injection.
  2. Group 2: Application of Facial Massager on the buccal mucosa 30 seconds prior to and during the injection.
  3. Group 3: Application of 20% Benzocaine gel for 2 minutes + Facial Massager applied to the buccal mucosa 30 seconds prior to and during the injection.
  4. Infection Control & Sterilization

To ensure patient safety, the following protocol for the non-medical T-massager will be implemented:

  • Barrier Protection: The device will be encased in a single-use, disposable polyethylene sleeve (Digital Sensor Sleeve) and secured with tape.
  • Disinfection: After barrier removal, a "Double-Wipe" method using 70% Isopropyl Alcohol wipe will be used.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
self reort of pain
Time Frame: after injection

after injection

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
