Vissupplementation is a minimally invasive and simple technique that replaces synovial fluid with intra-articular injection of hyaluronic acid (HA). This is a kind of treatment suitable for treating temporomandibular joint (TMD) diseases, such as osteoarthritis and disc displacement, with or without reduction. Aim: The purpose of the present study was to evaluate the use of viscossuplementation in the treatment of temporomandibular joint dysfunctions. Material and Methods: The literature, for this, was searched in PubMed and Scielo databases, from 2009 to 2019, using "Viscosuplementation", "Hyaluronic Acid", "Temporomandibular Joint Dysfunctions" and "Osteoarthritis". Exclusion criteria were those that tested on animals and were not related to the subject. Seven selected layouts. Results: From the reading of the studies, it is believed that hyaluronic acid is beneficial in reducing pain levels, improving the patient's quality of life and mandibular function, even being superior to placebo. However, there are still studies that point out the differences in relation to this technique, due to the question of the molecular weight of HA, the number of sessions performed. Conclusion: Therefore, the patients with temporomandibular joint disorders may improve their clinical setting with a viscossupplementation function, however, greater product standardization and new research studies are needed.
O estudo objetivou revisar a literatura sobre a relação entre disfunção temporomandibular (DTM) e fatores psicológicos. Trata-se de uma revisão de literatura com abordagem qualitativa. As bases de dados foram PubMed e BIREME, no período de 2008 a 2018. Como critérios de inclusão: artigos publicados na língua inglesa, com os descritores “temporomandibular joint disorder”, “anxiety”, “depression”, “stress’’ e ‘‘psychological”. Foram excluídos os artigos de revisão de literatura e artigos onde o componente psicológico foi apenas citado e não avaliado propriamente. Caracterizaram-se oito artigos, dos quais os resultados apontaram a correlação significativa entre DTM e comorbidades psicossociais, somáticas e comportamentais. Os fatores psicológicos como somatização, depressão, ansiedade e angústia, principalmente relacionadas ao gênero feminino, configuram um impacto significativo na prevalência de DTM. Nota-se que existe relação aos fatores citados, dessa forma, necessita da assistência interdisciplinar em virtude da natureza físico-psicológica, ou seja, participação da psicologia para intensificação do tratamento odontológico.
The purpose of this article is to report a clinical case of a patient with TMD, evaluating the efficacy of dry needling as a treatment. The study was carried out in a dental clinic of higher education, where the evaluation of the patient was performed in order to conclude a correct diagnosis complementing with the use of dry needling. Patient, female, 38 years old, reported pain throughout the muscular region of the face, where it was more pronounced in the parotid-massometric region, with spreading to the temporal region. After performing the evaluation in addition to the percussion and palpation tests, the patient was diagnosed with spreading myofascial pain, in addition to headache attributed to TMD bilaterally. As a therapeutic approach, the dry needling technique was performed, in addition to the orientation of Cognitive Behavioral Therapy, since the patient reported having parafunctional habits. The techniques used produced an effective improvement to the patient, where the patient reports a relief of the muscular pains when performing the dry needling.
To evaluate the shear bond strength and the fracture type of orthodontic tubes bonded directly with composite resin throughout the enamel surface. 30 bovine teeth were cut into 3 slices with 5 mm each and embedded in PVC pipes with acrylic resin exposing the buccal face. Subsequently, the teeth were submitted to conventional bonding techniques. Natural Ortho resin was applied for direct bonding of Edgewise Standard orthodontic tubes (Morelli®) and light-cured for 20s. A different viscosity resin was chosen and light-cured for 40s to reinforce the tube surface. The samples were divided into the following groups: Orthodontic tube with direct bonding without reinforcement (CONTROL), Tube with Natural Ortho resin + Reinforcement (NO + NO), Tube with Natural Ortho resin + Reinforcement with Flow resin (NO + FL). These were submitted to shear bond strength; immediate and 1-year aging fracture analysis after simulated through thermocycling. In the shear bond strength test, the group of orthodontic tubes that were directly bonded with Natural Ortho resin and reinforced (NO + NO) showed greater strength results after 24 hours and 1 year with values of (p=0.0225) and (p=0.0273). It was statistically differentto the NO + FL and CONTROL reinforced groups. In the fracture analysis, the NO +NO group was classified immediately as composite cohesive, and mixed failure after aging by thermocycling. The addition of a composite resin layer on the surface of the directly bonded orthodontic tube improved bond strength. The reinforcement must be carried out in regular consistency and the use of Flow resin is not indicated.
Introdução: A interação entre as novas técnicas e novos materiais restauradores é notória em casos de dentes tratados endodonticamente com destruição coronária, como o uso de pinos de fibra de vidro, considerado um material com boas propriedades mecânicas e estéticas. Pode, ainda, ser associado a outras técnicas restauradoras, caracterizando um tratamento multidisciplinar. Relato de caso: Paciente do sexo feminino, normossistêmica, compareceu à Unifametro (Fortaleza) relatando insatisfação com a estética do sorriso. Após uma anamnese criteriosa, identificaram-se, nos dentes #12 e #21, destruições coronárias classificadas como classe IV na classificação de Black; nos dentes #11 e #21 havia restaurações com cárie secundária e cores irregulares; dente #22 com fratura em mais de 50% da sua porção coronária, com substrato escurecido e tratamento endodôntico insatisfatório. Durante o planejamento do caso, optou-se por um tratamento multidisciplinar, com adequação do meio bucal, retratamento endodôntico do dente #12 e cimentação de pino de fibra de vidro. Nos demais dentes, foram realizadas estratificações com resina composta. Conclusão: A utilização de técnicas mais simplificadas e relevantes é uma adequada opção estética e funcional para dentes com tratamentos endodônticos e com cáries severas.
