Influência de abordagens biopsicossociais e autocuidados no controle das disfunções temporomandibulares crônicas

BACKGROUND AND OBJECTIVES: Temporomandibular joint disorder (TMD), which is a musculoskeletal condition of the masticatory system, may become chronic and further worsen quality of life (QL) of patients. Due to the inter-relationship between physical and emotional symptoms, there is an increasing search for the integrative model, which includes psychosocial approaches for the treatment of painful conditions. This study aimed at reviewing in the literature the impact of education and simple self-care modalities on pain and disorders related to chronic painful TMD. CONTENTS: Psychosocial factors are often involved with pain chronicity, making bio-behavioral approaches increasingly more indicated to change pain perception and to decrease distress and psychosocial changes which go along with persistent pain. CONCLUSION: Current literature, although not extensive, indicates positive results of education and self-care methods for chronic painful TMD. Further studies are needed to reinforce such findings and spread the application of such approaches to control chronic and TMD pain.

Can cone-beam computed tomography superimposition help orthodontists better understand relapse in surgical patients?

This case report describes the interdisciplinary treatment of a 19-year-old Brazilian man with a Class I malocclusion, a hyperdivergent profile, an anterior open bite, and signs of temporomandibular joint internal derangement. The treatment plan included evaluation with a temporomandibular joint specialist and a rheumatologist, orthodontic appliances, and maxillomandibular surgical advancement with counterclockwise rotation. Cone-beam computed tomography images were taken before and after surgery at different times and superimposed at the cranial base to assess the changes after orthognathic surgery and to monitor quantitatively the internal derangement of the temporomandibular joints and surgical relapse. Our protocol can improve the orthodontist's understanding of surgical instability, demonstrate the clinical value of cone-beam computed tomography analysis beyond the multiplanar reconstruction, and guide patient management for the best outcome possible.

Ertty System®: distalização segmentar

Introduction: Ertty System® is an intraoral system of biomechanical forces to move teeth anteroposteriorly. The application of forces on this system results in the distalization of the molar and all lateral segment in the side to be distalized, including premolars and canine, resulting in alveolar bone remodeling. This system is indicated to correct uni- or bilateral maxillary dental Class II malocclusion in permanent dentition both in children and adults. It is contraindicated in case of skeletal asymmetries, protrusion of maxillary and mandibular teeth, skeletal Class II and Class II subdivision malocclusions with mandibular midline deviation. This study describes Ertty System® and presents two clinical cases treated using this system. The two female patients presented with Class II malocclusion subdivision and maxillary midline deviation. Results: It was achieved correct alignment and leveling, Class I dental relation and correction of upper midline. Conclusion: The success and stability of results confirmed diagnosis and treatment adequacy.

Influencia dos hábitos de sucção na manifestação de dor temporo-mandibular: revisão sistemática

Objective: To assess the attitudes and knowledge about hepatitis by scholars and dental practitioners from Recife and its metropolitan region. Method: The research protocol was submitted and approved by the Ethics and Human Research Committee of the Federal University of Pernambuco. There were included 230 undergraduate students in dentistry and 104 dentists who exercise their professional activity in Recife and its Metropolitan Region. They signed a consent form and answered a questionnaire, the evaluative instrument, with objective questions about biosafety, transmission of hepatitis and sexually transmitted diseases. Results: About the types of hepatitis 133 (57.8%) students and 61 (58.7%) professionals claimed to know the types A, B and C. Concerning transmission 31 (13.5%) students and 25 (24.0%) professionals said that the main route of transmission were sexual and bloodstream respectively. Relating to imunization 221 (96.1%) students and 99 (95.2%) professionals reported that have been vaccinated against hepatitis B, however, only 126 (54.8%) students and 55 (52.9%) professionals have followed the immunization’s schema. Regarding the cleaning of the office equipment, 18.7% of the students replied that they do not know who does it. 56.7% of professionals said that it was performed with alcohol 70 ° GL.Conclusions: The findings indicate that there is a concern for biosafety but the knowledge about the forms of hepatitis transmission and biosecurity measures need to be better settled.

Health professionals ethical and legal liability on patient’s inadequate clarification in order to obtain free and informed consent

It is required that patients are provided information about therapeutic possibilities, showing the risks, benefits, prognosis and costs of each possible and indicated alternative. This is an ethical and legal resolution. However, health professionals possess the clinical/technical/scientific knowledge and determine what information will be (or not) provided. The patient in question decides to undergo a treatment, providing his/her free and informed consent on the basis of the data presented. Unfortunately, some professionals may not provide all the information necessary for making an informed decision or, after obtaining the consent of the patient, may provide him information that causes the patient to give up on the treatment initially accepted. Such information, if relevant, and not a supervening fact, should have been provided initially. However, the information may not be entirely true, and bring the patient, for instance, to decide based on inadequately presented risks. The craniofacial rehabilitation of the temporomandibular joint (TMJ) by means of TMJ prosthesis, is indicated in many situations. Often, patients in need of such prostheses have aesthetic and functional problems and the rehabilitation expectations run high. This work presents a case and discusses ethical and legal issues, including the liability of partial and inadequate information to a patient.

Reabsorção condilar progressiva: revisão de literatura

The progressive condylar resorption is a irreversible complication that can result in malocclusion and facial deformity that can happen especially in postoperative orthognathic surgery of mandibular advancement or combined surgery. Predominantly affect young women, bearers of malocclusions of skeletal class II and with incidence of temporomandibular disorders prior to surgical treatment. Its exact etiology and pathogenesis remain unclear. The purpose of this article is to make a literature review of the last 10 years on the progressive condylar resorption. For this, we used the Medline database for articles in the English language. Then, 13 articles were found, evaluated and compared on predisposing factors, etiology, diagnosis and clinical management.

Sintomas auditivos e desordens temporomandibulares

Introduction: A variety of hypotheses have been proposed to explain the association between temporomandibular disorders and hearing symptoms, including the many anatomical and/or neurological ways, as of a muscle or joint dysfunction, can cause such symptoms. Objective: The purpose of this study is to discuss, through a systematic review of literature, the interrelation between hearing symptoms and temporomandibular disorders. Material and Methods: We consulted the Medline/PubMed, ISI and Scielo in the period 1918 to 2008. The terms related to the research were: “temporomandibular disorders”, “signs and symptoms of temporomandibular disorders”, “otologic symptoms” and “aural symptoms”, where 19 papers were included using the pre-selected criteria for the manufacture of a meta-analysis. Results: According to the findings, the hearing symptoms most often associated with temporomandibular disorders were otalgia and tinnitus, followed by vertigo and hearing loss, respectively. Conclusions: It’s clear the correlation between hearing symptoms and temporomandibular disorders, however there is a need clinical and scientific research more complex to prove the specific cause-effect relationships between them.

Dor orofacial

The orofacial pain, also known by the generic term dysfunction, is highly prevalent in the general population, causing great discomfort to the patients.

Acupuncture as therapeutic resource in patient with bruxism

Bruxism is the harmful habit of clenching or grinding the teeth during the day and / or night, with unconscious pattern, with particular intensity and frequency, outside the functional movements of chewing and swallowing. It is accepted that bruxism is a response controlled by the neurotransmitters dopamine system associated with emotional component. The proposed of treatment of bruxism with acupuncture aims to stimulate sensory fibers of the peripheral nervous system leading to electrical transmission by neurons sufficient to produce changes in the central nervous system. As a consequence there is the release of substances (cortisol, endorphins, dopamine, noradrenaline and serotonin) that promote wellness and restoration of harmony, be it psychological, biological and / or behavioral.
