The purpose of this study is to determine whether osteopathic manipulative treatment associated to Dentistry care and speech therapy improves pain and function in individuals with temporomandibular disorders.
A standardized TMD examination was executed in all patients by a dentist following the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/ TMD) questionnaire, Axis I and II, portuguese version. The RDC/ TMD is compound by a 31 items questionnaire and a ten items clinical exam. All these items are related to patients symptoms and signs; to mandibular functional impairment; and social-demographics, social-economics, psychological e psychosocial data. The first part as Axis I tend to clinical assess and classify the TMD and the second, as Axis II propose a chronic pain score that could quantify the psychosocial impairment and present a subjects profile.
Others assessment instruments utilized on the research were the VAS consists in a 10 cm horizontal line with "no pain" on the left side and "worst pain" on right side, then the subjects were instructed to vertical risk the level of pain. The digital caliper with a 0,03 mm precision was used to measure the maximal mouth opening (MMO) as the maximal inter-incisal vertical distance of the incisors. The subjects were seated at 90° with neutral head position and solicited to open their mouths the maximum they can unassisted and without pain, maximum unassisted opening and maximum assisted opening. Also, a portable digital pressure algometer for measuring sensitivity to pressure before it became painful. The masseters and temporalis muscles trigger point location were used as reference to guarantee the reproducibility of the proceeding as well as to assess the always the same site. The statistical analysis was performed using the means comparisons for the parametric tests through Student T test and for the non-parametrical data, Wilcoxon. Also, it was made the descriptive statistical with frequencies analysis.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Conventional Group | Active Comparator | Individuals with temporomandibular disorder were used rigid occlusal splints and medication (Ibuprofen and Cyclobenzaprine Hydrochloride) under the dentist professor supervision. Likewise, speech therapists performed assessments, measurements, massages, stretches and therapeutic exercises for head, neck and mouth regions during four weeks. |
|
| Osteopathic Group | Experimental | Individuals with temporomandibular disorder received the same assistance of Conventional Group, cited above, plus the osteopathic care during 20 to 30 minutes once a week until the end of dental and speech therapy treatments (4 weeks). |

| Osteopathic Group | Other | Same assistance of Conventional Group, cited above, plus the osteopathic care during 20 to 30 minutes once a week during four weeks. The osteopathic treatment consisted in an individualized assessment of mobility restrictions of myofascial tissues and joints and the application of smooth techniques such myofascial release, membranous strain and counterstrain, muscle energy, cranial and high velocity and low amplitude. |
|
| Ibuprofen | Drug | The medication was prescribed by the dentist as nonsteroidal anti-inflammatory drug if necessary. |
|
|
| Cyclobenzaprine Hydrochloride | Drug | The medication was prescribed by the dentist as muscle relaxer if necessary. |
