Symptoms of Temporomandibular Dysfunction in Patients Submitted to Bucco-Dental Surgery

Thaís Cristina Araújo Moreira, Lidia Audrey Rocha Valadas, Antônio Sérgio Guimarães


Objectives: To verify the symptoms of temporomandibular disorders (TMD) in a sample of patients who made dental surgery, before and after the procedure. Methods: This is a clinical, longitudinal and quantitative study. The study population consisted of patients of both genders, aged between 16 to 60 years, selected in the surgery service. The participants answered two questionnaires to evaluate the presence of TMD symptoms, the TMD-Pain Screener questionnaire and the questionnaire of the European Academy of Craniomandibular Disorders (EACD). Results: 110 patients were evaluated, the most female (p <0.05). When questioned about which surgery was performed, the highest prevalence was of impacted third molars (37.3%), followed by third erupted molars (27.2%) and third molars included (18.2%). When evaluating the results of the TMD-Pain Screener questionnaire, there was statistical significance for all questions both in the pre- and post-operative periods. Regarding the EACD questionnaire there was no statistical significance for pain. When comparing the questionnaires at different times, there was no statistical difference in the EACD questionnaire and TMD-Pain Screener, only in relation to mouth opening and laterality movements (p = 0.04). Patients with and without TMD symptoms showed no statistical significance for any of the questionnaires. Conclusion: It was concluded that there was a high prevalence of painful TMD symptoms in patients who sought dental surgery. After the surgical procedure, there was a significant decrease in mandibular pain in the opening, protrusion and laterality movements. Thus, dental surgeries performed under adequate operative conditions do not affect TMD symptoms in patients.

Anatomic and dynamic aspects of stomatognathic structures in osteogenesis imperfecta: a case report



The osteogenesis imperfecta congenita (OMIM 166210) type II phenotype can be caused by mutation in either the COL1A1 gene or the COL1A2 gene that encode the chains of type I procollagen, the major protein in bones. Patients can therefore present a combination of features, including multiple long bone fractures and deformities, growth deficiency, joint laxity, hearing loss, blue sclera, and dentinogenesis imperfecta. The purpose of this study is to describe a clinical case of this syndrome, focusing on the anatomy of the temporomandibular joint (TMJ) that was assessed using computed tomography (CT) method. Clinical examination included evaluation of mandibular dynamics and investigation of temporomandibular dysfunction (TMD).

[Characterization of patients in a temporomandibular dysfunction and orofacial pain outpatient clinic]

[Article in Portuguese]


This study aims to describe the characteristics of patients at a temporomandibular dysfunction and orofacial pain outpatient clinic and to discuss the insertion of nursing care in this service. A questionnaire based on the steps of the Nursing Process was applied to a sample of 150 patients attended from May to August 2003. Patients from both genders and aged between 12 and 77 years old were sequentially admitted to the study. Population data revealed that a majority was female (85%); the predominant age was from 21 to 60 years old (76%); only 3% did not present any formal instruction. The nursing role introduced in this multidisciplinary clinic created conditions to assess demographic and epidemiologic data, identify user needs and develop self-care abilities and attitudes. The proposed model made is possible to organize data collection and promote research.

Temporomandibular joint involvement in a patient with centronuclear myopathy



We describe here the temporomandibular joint and masticatory muscle abnormalities disclosed by computed tomography and magnetic resonance imaging in a 25-year-old man with centronuclear myopathy (a congenital myopathy) who presented with marked limitation of jaw movements. We found an intense and general fatty replacement of the masticatory muscles, and magnetic resonance imaging signals indicated articular fibrosis. We conclude that in centronuclear myopathy, the presence of weakness and hypomotility of the masticatory muscles can induce chronic abnormalities of the temporomandibular joint.
