Background: Among the instrumental devices that have been proposed over the years to integrate the clinical evaluation of temporomandibular joint disorders (TMD), imaging techniques are the most studied, showing that magnetic resonance imaging (MRI) is the technique most need to describe the anatomy of the TMJ and to evaluate the correlation of imaging findings with the clinical diagnosis . Despite the amount available studies on the use of MRI for evaluation of TMJ disorders and treatments, there is a lack of studies that evaluate the imaging findings after physical therapy. Purpose: To evaluate the influence of nonspecific mandibular mobilization about the positioning of the articular disc by MRI in individuals with TMD diagnosis of anterior disc displacement with and without reduction according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Analyze the behavior of pain through the numerical scale of pain assessment (END) at baseline and after each treatment session, the quality of life of individuals with TMD at baseline, immediately, three and six months after the treatment sessions by the World Health Organization Quality of Life Assessment (WHOQOL - BREF), and The Patient's Specific Functional Scale (PSFS) at baseline and after treatment. The treatment will be performed three times a week during four weeks. Metodology: This is a randomized, placebo controlled, blind study designed to assess the effects of techniques nonspecific mandibular mobilization x placebo. Individuals will be randomized and divided into two groups: Group A (intervention) and Group B (placebo). Statistic analysis: The positioning of the articular disc, extracted through the use of MRI, will be considered the primary outcome and, as a secondary outcome will be assessed the quality of life, pain and function after treatment. The adherence of the data to a Gaussian curve will be verified by the Shapiro-Wilk and the data are expressed as mean values and standard deviation. Two-way repeated measures analysis of variance with Bonferroni post hoc test will be used for inter-and intra-group comparisons. The significance level is adjusted p ≤ 0.05.

Introduction: Molar incisor hypomineralization (MIH) is a qualitative defect of enamel development that occurs in the mineralization phase. MIH affects one or more permanent molars and, occasionally, permanent incisors.
Objective: The aim of the proposed study is to determine whether photobiomodulation combined with a new self-cure resin improves hypersensitivity in molars with MIH and caries (primary outcome). Secondary outcomes include assessing the clinical performance of the self-cure composite resin in terms of restoration longevity and comparing the effectiveness of three interventions-photobiomodulation combined with self-cure resin, self-cure resin alone, and photobiomodulation combined with bulkfill photopolymerizable resin-in controlling hypersensitivity over time.
Methods and analysis: Permanent molars with MIH in patients eight to 12 years of age will be allocated to three groups. Group 1: photobiomodulation + self-cure composite resin restoration; Group 2: self-cure composite resin restoration; Group 3: photobiomodulation + restoration in bulk-fill photopolymerizable composite resin. Photobiomodulation will be performed in a single session involving low-level laser administered to four different points. The laser will be used at a wavelength of 808 nm, power of 100 mW and energy of 1 J per points; irradiance will be 3571 mW/cm², with a total radiant exposure of 35.7 J/cm². Data normality will be checked using the Shapiro-Wilk test, and variance homogeneity will be assessed with the Levene test. Descriptive statistics will be used to present the data, with continuous variables expressed as mean and standard deviation, and categorical variables by relative frequency. To compare the VAS and SCASS scales, repeated measures ANOVA will be employed, considering the 3 groups and 5 time points. Bonferroni adjustment will be applied for post-hoc comparisons. Sphericity will be tested with Mauchly's test, and if violated, Greenhouse-Geisser correction will be applied. A significance level of 0.05 will be adopted. Ethics and dissemination: This protocol received approval from the Human Research Ethics Committee of Nove de Julho University (certificate number: xxxxxxx). The legal guardians of the children will agree to participation by signing a statement of informed consent. The results will be published in a peer-review journal and the data will be made available upon request.

TECAR therapy (Transfer of Energy Capacitive and Resistive) is a type of diathermy that uses radiant energy to generate endogenous heat. However, to the date there are no studies investigating the effects of TECAR therapy on exercise preconditioning and post-exercise recovery in humans. Therefore, the aim of this project is to assess the effects of different treatment protocols of TECAR therapy on. exercise preconditioning and post-exercise recovery in humans
