Trial summary

Low intensity laser therapy (LILT) has been widely applied in pain relief in several clinical situations. With the advent of new LED-based (light emitting diode) light sources, the need of further clinical experiments aiming to compare the effectiveness between them is paramount.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 50 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Thirty patients (from 18 to 50 years old) presenting signs and symptoms of TMD were selected to participate in the study. The patients received care at a private dental office in Ribeirao Preto, São Paulo, Brazil (NILO- Integrated Center for Laser in Dentistry). The patients´ age ranged from 18 to 40 years old, being 08 male and 22 female. The signs and symptoms evaluated by a trained professional were as follow: pain during palpation in the TMJ area, pain on associated muscles (masseter and temporal), and limited or painful jaw movement with impaired oral aperture.

About this study

Official title: COMPARATIVE CLINICAL STUDY OF LIGHT ANALGESIC EFFECT ON TEMPOROMANDIBULAR DISORDER (TMD) USING RED AND INFRARED LED-THERAPY

Low intensity laser therapy (LILT) has been widely applied in pain relief in several clinical situations. With the advent of new LED-based (light emitting diode) light sources, the need of further clinical experiments aiming to compare the effectiveness between them is paramount.

Read the detailed description

Aims: Low intensity laser therapy (LILT) has been widely applied in pain relief in several clinical situations. With the advent of new LED-based (light emitting diode)light sources, the need of further clinical experiments aiming to compare the effectiveness between them is paramount. Method: This study proposes an evaluation of analgesic effect in TMD (temporomandibular disorders) using two different LEDs systems, one emitting at the spectral band of red (630 +/-5 nm) and the other at infrared band (850 +/-5 nm), and compare the results with a laser treated control group (780nm diode laser using 105.7 J/cm2). Mandibular range of motion and report of pain were evaluated via appropriate equipment developed to do this end. Power output was 150mW, tip area was 0.5 cm² for both sources. Fluency or dose chosen was 18 J/cm² for each point of application, around the TMJ, on both sides. Five points were irradiated on TMJ, temporal and masseter muscles. Eight irradiation sessions were done and follow up was performed 7 and 30 days, after last session. Thirty patients were enrolled and they were selected randomly for each treatment, resulting in 10 patients per group (infrared LED, red LED and Control Group using infrared Laser).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Relationships between pain and range of motion

    Pain score and mandibular range of motion

    Measured: 2 months

Secondary outcomes (1)
  1. Research Diagnostic Criteria(RDC)/Temporomandibular Disorders (DTM)

    RDC/DTM diagnostic exam for research of arthralgia and chronic myofascial pain. The signs and symptoms evaluated by a trained professional were as follow: pain during palpation in the temporomandibular joint, pain on associated muscles (masseter and temporal), and limited or painful jaw movement with impaired oral aperture.

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

A study testing Red LED, INFRARED LED and LASER in people with Temporomandibular Disorder, run by University of Sao Paulo at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Jul 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Relationships between pain and range of motion (time frame: 2 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01873937, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jul 2013.
