BACKGROUND AND OBJECTIVES: Temporomandibular dysfunction consists of frequent non-dental pain in the orofacial region of multifactorial origin and interdisciplinary treatment, among them, acupuncture. The treatment of temporomandibular dysfunction acts both in muscle relaxation and pain control, trying to achieve the physical, mental, and emotional balance of the patient, thus reducing anxiety and improving the quality of life. The objective of this study was to evaluate acupuncture as a treatment for temporomandibular dysfunction. METHODS: A total of 34 volunteers screened and selected at the Federal University of Mato Grosso do Sul, diagnosed with muscle dysfunction according to the Research Diagnostic Criteria. They were randomly divided into two equal groups: group 1 treated with occlusal plaque, massage, thermotherapy and selfcare guidelines; and group 2 treated with six acupuncture sessions lasting 30 minutes each. The pain was evaluated by the visual analog scale, and an algometer to assess the muscular tension of the temporal and masseter muscles. The limitation of mouth opening was measured with the use of calipers. The Mann-Whitney test was used for the non-normal distribution (visual analog scale and tension threshold) between the two groups (G1 and G2), and the Friedman test to compare the assessment periods (beginning of the treatment, after six weeks and four months) with a significance level of 5%. RESULTS: There was no difference in mouth opening, visual analog scale scores, or muscle tension threshold in relation to the type of treatment used. Both groups improved after six weeks of treatment. There was no statistical difference in the values obtained after six weeks and after four months.
Objetivo: Esta pesquisa avaliou a estabilidade dimensional de modelos obtidos de moldes de alginato utilizando a técnica de união dos análogos. Materiais e Métodos: foi utilizado um modelo mestre representando uma mandíbula com 4 implantes osseointegrados instalados, sobre o qual foi realizado a moldagem com moldeira aberta dos transferentes unidos por fio metálico rígido e resina acrílica autopolimerizável, utilizando o alginato. Foram feitas 40 moldagens ao todo, sendo 20 para cada grupo. Após as moldagens, os moldes foram vazados utilizando gesso pedra de alta resistência, sendo que em um grupo foi realizada a união de análogos previamente. Após o término da reação de presa do gesso, os modelos foram levados para análise na lupa estereoscópica, onde foram realizadas 3 medições da distância dos análogos entre si, obtendo-se uma média para cada modelo. Resultados:As médias obtidas foram comparadas com a média da distância entre os análogos e enviadas para análise estatística para a obtenção dos resultados, utilizando o teste Tukey HSD. Os resultados mostraram que as medidas de ambos os grupos tiveram diferenças estatísticas em relação ao modelo mestre, sendo que com a união houve alteração nas medidas A e C e sem a união houve alteração nas medidas A, C e D. Conclusão: Concluiu-se que os modelos com maior fidelidade dimensional são os do grupo com a união de análogos.Descritores: Técnica de Moldagem Odontológica; Implantes Dentários; Prótese Dentária.
