Recruitment & Eligibility

• Status: Recruiting
• Sex: Not specified
• Target Recruitment: Not specified

Inclusion Criteria

Experimental group: volunteers with TMD, established through the application of the RDC / TMD; both genders; aged between 18 and 45 years; complete permanent dentition (optional presence of third molars) and no more than a missing premolar in the quadrant. For the control group the inclusion criteria are the same, except the presence of TMD.

Exclusion Criteria

Subjects presenting history of oral and maxillofacial surgery, facial trauma to the jaw, orthodontic treatment in less than two years, bone disease or neuromuscular facial malformations, severe malocclusion (anterior open bite, unilateral or bilateral posterior crossbite), parafunction habits, facial deformities, or pregnant patients were excluded.

Primary Outcome Measures

Name	Time	Method
In respect of craniofacial morphology is expected to find the prevalence of a facial type in experimental (100 TMD patients) and control (100 subjects without TMD) groups. The craniofacial morphology will be determined from cephalometric analysis after obtaining conventional lateral radiographs and individuals may present three facial types: brachyfacial, mesofacial and dolichofacial.

Secondary Outcome Measures

Name	Time	Method
It is expected that the presence of painful symptoms influence the masticatory function in individuals with different facial types. The masticatory function in patients which have pain in the temporomandibular joint and / or masticatory muscles will be evaluated through masticatory performance (by the chewing of chewable test material samples and analysis by the sieves method) and the maximum bite force (by the bilateral pressure sensors installed in the molar region,) and the masticatory ability by a questionnaire form.
