Study summary

The temporomandibular joint (TMJ) is closely related to neuromuscular components. A problem occurring in any of these components or parts of the TMJ interferes with the harmonic functioning of the TMJ and invites temporomandibular joint disorders (TMD).Management of TMD can be conservative or surgical. Physiotherapy, local steam application, external muscle massage, occlusal adjustment, analgesic and physiotherapeutic medication and splint treatments are the most frequently recommended conservative treatments. Today, occlusal adjustments are made with the help of a prosthetic or orthodontic appliance. With these intraorally used occlusal splints, a balanced occlusal contact is achieved without applying any force to the mandible in the resting position. Occlusal splints are available in different designs and different construction materials. The stabilization splint, which is one of the most frequently used occlusal splints, and the modified Hawley splint are appliances produced from hard materials. However, some researchers have commented that soft splints produced from resilient materials may also be useful in the distribution of excessive force formed in parafunctional habits. While there are studies stating that hard splints provide more successful results than soft splints in functional problems of the chewing system, there are also studies reporting that they have similar efficacy on muscle pain after short-term use. However, there are no studies in the literature that compare their efficacy in short-term and long-term myalgia patients and demonstrate their efficacy using an objective test such as digital occlusion analysis. There was no study on the effectiveness of different splints on the patient's quality of life. It would be appropriate to carry out our study to fill this gap in the literature.The main purpose of this study is to digitally examine and compare the effects of three different treatment methods (medical therapy, medical therapy+soft splint, medical therapy +hard splint) applied to patients diagnosed with facial myalgia after temporomandibular joint examination on the existing occlusion changes.

Study arms

  • No intervention
    Medical therapy

    One non-steroidal anti-inflammatory drug (400mg etodolac) and one muscle relaxant drug (4 mg thiocolchicoside) were prescribed to the patients in this group.

  • Active comparator
    Hard Splint Therapy

    The patients in this group were asked to use a hard splint delivered to them to use at night.

Interventions

  • DrugEtodolac 400 MG

    Patients were asked to drink a tablet containing 400 mg of etodolac every 24 hours with a glass of water.

    Also known as: Etol Fort

  • DrugThiocolchicoside

    Patients were asked to drink a tablet containing 4 mg of thiocolchicoside every 24 hours with a glass of water.

What researchers measure

Primary outcomes

  1. Effects of treatment method on occlusion time parameters

    Occlusion times, left and right lateral disclusion times and protrusive disclusion times are among the occlusion parameters. In each control session, researchers will record these parameters in seconds using the T-Scan III system.

    Time frame: 1 week- 6 month

  2. Effects of treatment method on distribution of right-left occlusion force percentages

    In each control session, researchers will record these parameters as percentages using the T-Scan III system.

    Time frame: 1 week- 6 month
