Respiratory Functions and Respiratory Muscle Strength in Patients With Temporomandibular Joint Dysfunction
Condition: Temporomandibular Joint Dysfunction Syndrome
MeSH terms: Joint Diseases; Temporomandibular Joint Disorders; Temporomandibular Joint Dysfunction Syndrome
Study type: Observational

Summary: 
      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.

Intervention name(s): Clinical Assessment
Intervention type(s): Other
Intervention description(s): The demographic information and clinical findings of the participants were recorded. Mandible movements evaluation with a digital caliper. The Visual Analogue Scale (VAS) to measure the severity of pain at rest and during activity. Cervical lordosis and shoulder posture assessment, Fonseca Anamnestic Index for TMD severity classification. Spirometric measurement to evaluate respiratory functions of all participants and intraoral pressure measurement to determine respiratory muscle strength.
Observational model: Case-Control
Time perspective: Prospective
Sampling method: Probability Sample
Study population: 
        The population of the study consists of cases diagnosed with TMD in Batman Training and
        Research Hospital between August 2021 and December 2021 and individuals who comply with the
        World Health Organization (WHO) definition of healthy person. The sample size of the study
        was calculated using the G-Power 3.1 (G-Power, Germany) program. The sample size was found
        to be 23 individuals in each group and a total of 46 individuals, with effect size 0.75,
        alpha 5%, and test power 80%.
