Respiratory Functions and Respiratory Muscle Strength in Patients With Temporomandibular Joint Dysfunction

In our study, it was aimed to evaluate respiratory functions and respiratory muscle strength in patients diagnosed with temporomandibular dysfunction (TMD) and to compare them with healthy individuals. The study was conducted with a total of 46 participants, 23 of whom were diagnosed with TMD and 23 healthy individuals, at Batman Training and Research Hospital between August 2021 and December 2021. In the evaluation, the demographic information and clinical findings of the participants were recorded. Mandible movements were evaluated with a digital caliper. For TMJ, the Visual Analogue Scale (VAS) was used to measure the severity of pain at rest and during activity. Cervical lordosis and shoulder posture assessment was done by distance measurement. Fonseca Anamnestic Index was used for TMD severity classification. Spirometric measurement was performed to evaluate respiratory functions of all participants and intraoral pressure measurement was performed to determine respiratory muscle strength. Statistical analyzes were performed using the IBM SPSS Statistics 26 program. Significance level was accepted as p\<0.05.
