About this study

Official title: Effectiveness of Arthrocentesis and the Occlusal Splint in Treatment of Disc Displacements of the Temporomandibular Joint

The goal of this clinical trial is to compare occlusal splint and arthrocentesis in patients with disc displacement with/without reduction. The main question it aims to answer are:

  • Is there a more effective treatment for this cases?

Participants will answer a questionary about pain and functional limitations.

Researchers will compare Group 1(occlusal plate) and Gruoup 2 (arthrocentesis) to see if there is pain reduction and functional improvement in patients with disc displacement with/without reduction

Read the detailed description

Introduction: Temporomandibular joint disc displacement is a disorder in which the articular disc is anteriorly displaced from its correct position in relation to the mandibular condyle and mandibular fossa. Traditionally, the initial treatment of disc displacements involves several conservative measures, among them, the stabilizing interocclusal splint. However, in cases where there is associated opening limitation, such as intermittent lock and closed-lock, arthrocentesis has been suggested as another initial treatment modality due to its faster effect in preventing disease progression to a more advanced stage, in addition to reducing the chances of pain chronicity and central sensitization. Objectives: The present study aimed to compare and analyze the effectiveness and benefits of performing arthrocentesis as the initial treatment in patients with DDWR with intermittent lock and in patients with DDWoR, compared to the stabilizing interocclusal splint. Additionally, it had as secondary objectives to characterize the sample according to demographic, systemic, local and psychosocial factors in both groups and to correlate the clinical characteristics of the included patients with the imaging findings of the MRI scans. Methods: A randomized, prospective, longitudinal pilot study was performed. The sample was obtained by convenience from a demand through consultations and referral, among patients treated at the Oral and Maxillofacial Surgery Service of HCFMUSP, from June 2021 to July 2023. Patients with diagnoses of: DDWR intermittent lock and DDWoR with opening mouth limitation. Study patients underwent an initial assessment using a clinical questionnaire (DC/TMD) and underwent an initial TMJ MRI. Then, they were randomly divided into two groups according to the treatment to which they would be submitted: stabilizing inter-occlusal splint (group 1) or arthrocentesis (group 2). After treatment was instituted, patients were evaluated at 1, 2, 3 and 6 months regarding clinical parameters of pain, functionality and psychosocial status.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Occlusal splintProcedure or surgery

    a stabilizing maxillary acrylic occlusal splint was made, flat, total and adjusted in central relation (RC).

  • ArthrocentesisProcedure or surgery

    The patient then underwent arthrocentesis of the temporomandibular joint itself, following the Nitzan technique.

What is being measured

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

  1. Jaw function available in mouth opening and moviments of jaw

    millimeter scale

    Measured: 6 months

Secondary outcomes (1)
  1. Pain available through of Visual Analogue Scale

    the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-10. It's been 0 (without pain) and 10 (worst pain)

    Measured: 6 months

Model description
Stabilizing interocclusal plate (IOP): a stabilizing maxillary acrylic occlusal plate was made, flat, total and adjusted in central relation (RC). Advice and guidance on the disease. Arthrocentesis: Delimitation of a corner-tragus line to mark points A (10mm in front of the tragus and 2mm below the CT line) and B (20mm in front of the tragus and 10mm below the CT line); Local intra- and extra-oral antisepsis with aqueous chlorhexidine 0.12% and 0.2%, respectively; Local anesthesia of the auriculotemporal and intra-capsular nerve with mepivacaine 2% + Epinephrine 1:100,000; Insertion of the first 30x0.8 mm needle at point A and injection of 2-3 mL of Lactated Ringer; Insert the second 30x0.8 mm needle into point B Wash with 100-200mL of Ringer Lactate; Removal of the second needle; Injection of 1mL of 20mg Triamcinolone diluted in 0.9% saline solution (1:1) through the needle at point A.

Questions about this trial

What is this clinical trial studying?

A study testing Occlusal splint and Arthrocentesis in people with Temporomandibular Joint Disc Displacement and Anterior Disc Displacement, run by University of Sao Paulo General Hospital 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 3 inclusion and 4 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 13 Feb 2024. 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?

Jaw function available in mouth opening and moviments of jaw (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 13 Feb 2024.
