the Relationship Between Parafunctional Habits, Pain and Functional Limitation of the Jaw
Condition: Temporomandibular Disorder; Pain, Joint
MeSH terms: Temporomandibular Joint Disorders; Temporomandibular Joint Dysfunction Syndrome; Arthralgia
Study type: Observational [Patient Registry]

Summary: 
      Temporomandibular disorders affect the general health and quality of life of individuals by
      causing deterioration in orofacial function and cause functional limitation. The use of
      Diagnostic Criteria for Temporomandibular Disorders (DC-TMD) is recommended for
      evidence-based evaluation of jaw joint disorders for clinical and research purposes.The aim
      of this study is to show the factors affecting the functional limitation of the jaw and to
      evaluate the relationship between the pain, Oral Behavioral Checklist and the Jaw Functional
      Limitation Scale (JFLS-8), using the Diagnostic Criteria for Temporomandibular Disorders
      (DC-TMD).

      75 patients with temporomandibular disorder (TMD) who will apply to the outpatient clinic of
      Istanbul Physical Therapy and Rehabilitation Training and Research Hospital will be included
      in our study.

      DC/TMD Axis I TMD Pain Screener Questionnaire, TMD Symptom Questionnaire, DC/TMD Axis II
      assessment tools 'Jaw Functional Limitation Scale-8 (JFLS-8) and Oral Behavioral Checklist
      (OBC) will be applied. In addition, demographic data will be questioned.

      Limitation Scale (JFLS-8), using the Diagnostic Criteria for Temporomandibular Disorders

      75 patients with temporomandibular disorder (TMD) who will apply to the outpatient clinic of
      Istanbul Physical Therapy and Rehabilitation Training and Research Hospital will be included
      in our study. Ethics Committee approval was obtained from Bakırköy Sadi Konuk Training and
      Research Hospital before starting the study and a voluntary consent form will be signed by
      the patients before the evaluation.

      In this cross-sectional study; 75 participants aged 18-65 years who has temporomandibular
      joint (TMJ) complaints for more than 3 months and has the cognitive ability to understand
      test instructions will be included. Patients with a history of previous TMJ operation,
      muscle, neurological or rheumatic disease that may affect TMJ, and a history of
      facial/cervical trauma or neoplasia will excluded from the study.

      DC/TMD Axis I TMD Pain Screener Questionnaire and TMD Symptom Questionnaire will be
      administered to the participants. To determine parafunctional habits and limitation of
      function, the DC/TMD Axis II assessment tools 'Jaw Functional Limitation Scale-8 (JFLS-8) and
      Oral Behavioral Checklist (OBC) will be applied. In addition, demographic data (age, gender,
      education level, occupation) will be questioned.
