This clinical trial aims to investigate whether treatment of temporomandibular joint disorder with a stabilizing occlusal splint is justified to alleviate somatosensory tinnitus. The main questions we aim to answer are:
* Determine if treatment of temporomandibular disorder with a stabilizing occlusal splint improves somatosensory tinnitus. * Identify which patient-related, tinnitus-related, and temporomandibular disorder-related factors contribute to the therapeutic effect.
Patients over 18 years old;
Sufferers of somatosensory tinnitus and TMD for more than 6 months;
Dentition in good health, with at least minimal occlusion up to the second premolars on both sides;
Availability for at least 4 months of follow-up;
None
Parallel
Stabilizing occlusal splint
DeviceMaxillary stabilizing occlusal splint, made of acrylic with 2mm thickness in the posterior region. Installed and evaluated monthly for 4 months.
placebo splint
DeviceMaxillary placebo non-occlusal splint, installed and evaluated monthly for 4 months.
Changes in somatosensory tinnitus after treatment of temporomandibular joint disorder with a stabilizing occlusal splint.
Tinnitus improvement was monitored using the tinnitus handicap inventory (THI). A 25-item questionnaire measuring tinnitus-related distress. Scores range from 0 to 100. It subjectively quantifies the impact of tinnitus on the patient's quality of life and classifies tinnitus into 5 degrees: I- negligible (0-16); II- mild (18-36); III- moderate (38-56); IV- severe (58-76); V- catastrophic (78-100).
Somatosensory tinnitus distress reduction after treatment of temporomandibular joint dysfunction with a stabilizing occlusal splint.
Tinnitus distress was monitored by a Visual Analog Scale (VAS): Patients rated tinnitus distress on 10-point scale (0 = none; 10 = extreme)
