NCT07666360 | Recruiting

• 1 other identifier: 26.10.2024-10/1051
• Study Type: observational
• Target: 60
• Locations: 1 country
• Sites: 1

Brief Summary

This cross-sectional study will examine the relationship between mandibular dysfunction, cervical joint position sense, craniovertebral angle, neck pain, and temporomandibular dysfunction (TMD) severity. TMD severity, mandibular function, cervical proprioception, craniovertebral angle, and neck pain history will be assessed using standardized clinical tools and questionnaires. The study will evaluate the associations between these variables and determine the factors that may predict TMD severity.

Conditions

Temporomandibular Disorder

Outcome Measures

Primary Outcomes (1)

• Temporomandibular Dysfunction Severity

  TMD severity will be assessed using the Fonseca Anamnestic Index, which evaluates the severity of temporomandibular dysfunction symptoms. It is a 10-item self-report questionnaire. Each item is scored as "Yes" (10 points), "Sometimes" (5 points), or "No" (0 points), with a total score calculated by summing all items.

  Single assessment at baseline (cross-sectional evaluation)

Secondary Outcomes (7)

• Cervical Extension Joint Position Sense

  Single assessment at baseline (cross-sectional evaluation)

• Cervical Flexion Joint Position Sense

  Single assessment at baseline (cross-sectional evaluation)

• Cervical Lateral Flexion Joint Position Sense

  Single assessment at baseline (cross-sectional evaluation)

• Cervical Rotation Joint Position Sense

  Single assessment at baseline (cross-sectional evaluation)

• Craniovertebral Angle

  Single assessment at baseline (cross-sectional evaluation)

Study Arms (1)

TMD Symptomatic Participants

Participants with temporomandibular dysfunction (TMD) symptoms will be included in the study. All participants will undergo clinical and questionnaire-based assessments to evaluate mandibular function, cervical joint position sense, craniovertebral angle, neck pain history, and TMD severity.

TMD Symptomatic Participants

Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

Adults aged 18 years or older with a Fonseca Anamnestic Index (FAI) score of 20 or higher who gave written consent were included. Participants were people with jaw (TMJ) and/or neck complaints. People were excluded if they had recent treatment (last 6 months) for the jaw or neck, used pain or muscle relaxant drugs, had previous neck or jaw surgery or major trauma, jaw dislocation or subluxation, missing teeth or dental prostheses, or neurological, rheumatologic, or systemic inflammatory diseases.

You may qualify if:

• Fonseca Anamnestic Index score \> 15
• aged 18 years and older

You may not qualify if:

• Received medical, orthodontic, or physiotherapy treatment targeting the temporomandibular joint and/or cervical region within the past six months
• used analgesic, anti-inflammatory, or muscle relaxant medications
• history of cervical spine or cranio-cervical surgery or major trauma
• a history of facial or TMJ trauma, TMJ subluxation or dislocation
• partial or complete dental prostheses
• had missing teeth
• neurological, rheumatological, or systemic inflammatory diseases
