25. Effect of occlusal splint thickness on electrical masticatory muscle activity during rest and clenching
The extent of separation between the maxillary and mandibular teeth in the fabrication of interocclusal splints designed to achieve efficiency and muscle relaxation is controversial and undefined in the literature. Based on this premise, the aim of this study was to evaluate the effect of interocclusal splint thicknesses of 3 and 6 millimeters on the electri

26. Effect of triiodothyronine on the maxilla and masseter muscles of the rat stomatognathic system
The maxilla and masseter muscles are components of the stomatognathic system involved in chewing, which is frequently affected by physical forces such as gravity, and by dental, orthodontic and orthopedic procedures. Thyroid hormones (TH) are known to regulate the expression of genes that control bone mass and the oxidative properties of muscles; however, li

27. Occlusal force, electromyographic activity of masticatory muscles and mandibular flexure of subjects with different facial types
OBJECTIVE: The aim of this study was to evaluate whether vertical facial patterns influence maximal occlusal force (MOF), masticatory muscle electromyographic (EMG) activity, and medial mandibular flexure (MMF). MATERIAL AND METHODS: Seventy-eight dentate subjects were divided into 3 groups by Ricketts's analysis: brachyfacial, mesofacial and dolychofacial.

28. Effect of experimental chewing on masticatory muscle pain onset
OBJECTIVES: To evaluate the effect of a chewing exercise on pain intensity and pressure-pain threshold in patients with myofascial pain. METHODS: Twenty-nine consecutive women diagnosed with myofascial pain (MFP) according to the Research Diagnostic Criteria comprised the experimental group and 15 healthy age-matched female were used as controls. Subjects we

30. Electromyographic analysis of the masseter, temporal and orbicularis oris muscles in young people with class II, division 1 malocclusion after treatment with extraoral appliance of occipital traction / Analise eletromiografica dos musculos masseter, temporal e orbicular da boca em jovens com maloclusão classe II, 1ª divisão dentaria, apos o uso de aparelho extrabucal de tração occipital
The surface electromyography is an excellent way to evaluate the muscle function. However, it presents limitations, because the great variability in the amplitude of the electromyographic signal obtained. To reduce this variability, has been proposed the normalization of the electromyographic signal. The process consist of dividing the raw electromyographic

31. Deglutição: estudo eletromiográfico da atividade dos músculos masseter, temporal e digástrico. / Swallowing: an electomyographic study of the activity of the masseter, temporal and digastric muscles.
Abstract In order to study the electromyographic activity of the masseter, temporal anterior and digastric in swallowing with and without dental occlusion, we evaluated 43 women, aged between 19 and 34 years (mean 23 years), students from the Undergraduate or Graduate Department of Speech Therapy of the Federal University of São Paulo. All had permanent tee

32. Influência de densidades do laser de baixa intensidade sobre o músculo masseter de ratos Wistar / Influence of densities of low level laser on the masseter muscle of rats Wistar
A laserterapia tem sido muito utilizada como tratamento alternativo em pacientes com dores crônicas relacionadas às disfunções temporomandibulares. Isso se deve aos efeitos: analgésico, antiinflamatório, miorrelaxante, de redução da fadiga durante as contrações tetânicas, aumento da força de mordida e diminuição da dor orofacial. Embora sejam o

33. Effect of facial vertical pattern on mastication and its parameters / Influencia do padrão facial vertical sobre a mastigação e seus parametros
Craniofacial vertical morphology may influence the disposition of masticatory muscles, affecting some functions of stomatognathic system. Thus, the aims of this study were to evaluate, in subjects with different facial vertical pattern, the quality of mastication and the following masticatory parameters: occlusal contact area, muscles activities, muscle effo

34. Ultrasound of the masticatory muscles and maximal molar bite force evaluation in individuals with osteoporosis in facial bones / Avaliação ultrassonográfica da musculatura mastigatória e da força de mordida molar máxima em indivíduos com osteoporose nos ossos da face
The stomatognathic system identifies a set of oral structures that develop common functions, characterized by constant mandible involvement. Like any system, has features of its own, but depends on the operation, or is closely linked to the function of other systems such as the nervous, circulatory and endocrine systems. Both the states of health and in illn

35. Electromyographic study (surface) of the chewing muscle in patients with and without temporomandibular dysfunction before and after orthognathic surgery / Estudo eletromiografico (de superficie) de musculos da mastigação em pacientes com e sem disfunção temporomandibular antes e depois do tratamento da cirurgia ortognatica
As deformidades dentofaciais são alterações dos tecidos duros e moles que podem ser resultado da influência genética ou ambiental. A cirurgia ortognática possibilita a correção cirúrgica das deformidades dentofaciais e sua importância se dá não apenas pela correção da oclusão e da funcionalidade, mas também pela melhora da estética facial.

36. Posterior crossbite and rapid maxillary expansion in mixed dentition stage : electromyographic, ultrassonographic and cephalometric / Mordida cruzada posterior e expansão rapida da maxila na fase da dentição mista : avaliação eletromiografica, ultrassonografica e cefalometrica
The aim of this thesis, comprised by three manuscripts, was to analyze the masticatory muscles of children with posterior crossbite (PCB) before and after rapid maxillary expansion (RME); as well to analyze if there are vertical and sagittal skeletal differences resulted by the uses of the banded or bonded RME appliance. In articles 1 and 2, 55 children (age
