There are about 10004 clinical studies being (or have been) conducted in Brazil. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
In deep carious lesions, presenting risk of pulp exposition, a treatment option is the partial caries removal of carious tissue followed by provisional restoration, while this approach is called indirect pulp capping. The aim of this double-blinding controlled randomized clinical trial is to evaluate the success of indirect pulp capping using only resin-modified glass ionomer, while the additional layer of calcium hydroxide was used as control. The sample of 112 molars and/or premolars (n=56), presenting deep carious lesions, from patients with age between 15 and 30 years treated in dental clinic at Department of Dentistry of Federal University of Sergipe. The selected carious lesions must be reached 2/3 of dentin, observed in bite-wing radiography, without pulp involving and/or other factor that to compromise the evaluation. After detailed anamneses, the selected teeth will be radiographed e all carious tissue from surrounding walls will be removed. At the floor of cavity, the carious tissue will be partially removed using hand dentin excavators, remaining the caries-affected dentin and avoiding the pulp exposition. The removed carious tissue from the floor of cavity will be evaluated for presence of Lactobacilos e Estreptococos Mutans, while the remaining dentin will be evaluated for consistency, colour and humidity. Randomly, the cavity will be provisionally restored with: Control - dress and cement of calcium hydroxide followed resin-modified glass ionomer; or Experimental - only resin-modified glass ionomer. The distance between the base of restoration and the pulp cavity cap will be measured by bitw-wing radiography. The patients will be re-evaluated after 15 days, while the teeth with compromised pulp vitality will be excluded from the study. The remaining patients will be evaluated after 6 months. The distance between the base of restoration and the pulp cavity cap will be measured again, followed by provisional restoration removal. The remaining caries-affected dentin from floor of cavity will be fully removed and a bacteriological evaluation performed. The consistency, colour and humidity of this tissue will be evaluated too. Finally, the permanent restorations will performed.
The purpose of this study is to assess the efficacy of intranasal esketamine plus an oral antidepressant compared with an oral antidepressant (active comparator) plus intranasal placebo in delaying relapse of depressive symptoms in participants with treatment-resistant depression (TRD) who are in stable remission after an induction and optimization course of intranasal esketamine plus an oral antidepressant.
Introduction: The effects of Low Level Laser Therapy (LLLT) on exercise-induced muscular damage have been studied over the last years. Studies have been conducted on animals and humans in order to try to show the benefits of the intervention, but there is still conflicting evidence about its protective and therapeutic effects. Objectives: To describe the effects of LLLT on pain, strength and muscular inflammation after plyometric exercise. Methods: A randomized, double-blinded, placebo-controlled trial with participation of 20 male healthy volunteers will be performed. Healthy and physically active individuals, aged between 18 and 35 years, with no history of injury on the lower limbs or contra-indications to maximal exercise performance will be included. A protocol of 10 series with 10 repetitions of the countermovement jump will be used to induce muscle damage at the lower limbs. Immediately before or after the exercise protocol, LLLT will be applied on one lower limb, while the other will receive placebo treatment. Phototherapy will be applied with an equipment of 810nm and a cluster with 5 diodes on 8 different points of the knee extensor muscle, totalizing a dosage of 240J. The placebo treatment will be held on the same way, but the equipment will be turned off. The volunteers will be evaluated at baseline (before the exercise protocol) and at follow-up of 24, 48 and 72 hours. The following outcomes will be evaluated: knee extensors isometric peak torque by Isokinetic Dynamometer, pain by Visual Analogue Scale and muscular tissue echo intensity by Ultrasonography.
This is a prospective, open label, single-center study, in kidney transplant recipients with stable renal function for 12 and 120 months after transplantation, that are in use use of calcineurin inhibitors, azathioprine, and prednisone. The prevalence of left ventricular hypertrophy will be investigated before and after conversion of azathioprine to everolimus. This study will evaluate as primary objectives: the prevalence of left ventricular mass hypertrophy in renal transplant recipients with azathioprine therapy. And assess the ability of everolimus to reduce left ventricular mass after conversion from Azathioprine, using sensitive methods such as MRI. And as secondaries objectives: Renal function (measured GFR) at 3 and 6 and 12 months after conversion, number and severity of episodes of acute rejection proven by biopsy, and the proteinuria at 3, 6 and 12 months after conversion.
Due to scarce published articles about this subject, the researchers aim to study the volume measurements of the brain cortex of patients with primary severe knee osteoarthrosis and those with chronic knee pain compared to healthy and non-symptomatic volunteers, correlating the neuroimaging of cerebral volumetry with pain intensity, pain duration, knee function and pressure pain threshold.
The correlation between tooth inclination and bone thickness and the comparison between thickness measurements and buccolingual inclination before and after dental decompensation will be evaluated through tridimensional images in individuals with class III dentofacial deformities.
The possible relationship between posture and instability of the masticatory muscles related to occlusion thus becomes the reason, the objective of this study. In this way, it will be possible to evaluate both postural alignment and postural balance in patients with signs and symptoms of temporomandibular joint disorder before and after the use of an occlusal plate. Our research will take place at the School of Odontology of the University of São Paulo in the clinics of the Occlusion and TMJ Services (SOA) and of the Envelhecer Sorrindo program, and the data will be collected in the Biophysics Laboratory of the School of Physical Education and Sports of the University of São Paulo. The population studies will be made up of 120 patients, 60 being part of the sample and the other 60 in the control group. All the patients in this study are over 20 years of age and are of both genders; the research criteria will be diagnosed by way of filling out the questionnaire of the RDC-TMD and complemented by way of diagnostic imaging via MRI of the temporomandibular joint. The study will be a clinical, randomized, controlled, prospective study and intervention. After the subjects' alignment is evaluated by way of photographs and their postural balance by way of a force platform, the group will the randomized; the sample group will receive an occlusal plate with criteria for occlusal stability (simultaneous, bilateral contacts with an absence of interference in the canine and anterior guides). The occlusal plate will be made from "Vacuum Form" acetate with a thickness of 1.5 mm; the simultaneous, bilateral, occlusal contacts and the canine and anterior guides will be obtained by way of autopolymerizable, acrylic resin with the mandible in a centric relationship. The occlusal plate will be controlled weekly. The control group will only receive orientation to do physiotherapeutic exercises seeking to correctly position the mandible in the resting position (maxillar teeth should be approximately 2 mm away from the mandibular teeth) while the tip of the tongue is positioned and accommodated on the roof of the mouth over the incisive papilla on the hard palate (without touching the teeth). The exercise will consist of repeatedly opening the mouth with the tongue cleaving to the roof of the mouth, 3 times per day, each period consisting of 3 sets with 15 repetitions. After 3 months, the two groups will be re-evaluated in terms of postural alignment and balance.
The Physical Therapy for children with Cerebral Palsy is of great complexity, in addition to improving the neuromotor components at the level of structure and body function, must empower them to carry out their activities and daily tasks and enable their social participation. In this way, the goals of Physical Therapy are related to promote the independence and functionality of the individual in situations of daily life. The participation of caregivers in the rehabilitation process can contribute to potentiate the gains obtained by physical therapy as well as to which they are incorporated into the day to day management of children with cerebral palsy. Objective: To assess whether Physical Therapy associated with the education of caregivers is effective in improving the functioning and quality of life of children with cerebral palsy. Hypothesis: The combination of Physical therapy with the education of caregivers improves in 15% the parameters analyzed against only 10% in those who are only Physical Therapy. Methods: 60 children with cerebral palsy after acceptance and signature in the term of informed consent will be randomly divided into 2 groups (G1: Physiotherapy and education of caregivers and G2: only Physical Therapy) to do 3 sessions of Physical Therapy and 1 weekly session of group education with duration of 45 min during 12 consecutive weeks. The evaluation will be carried out by means of the System of Classification of Motor Function Gross (GMFCS), the evaluation of Motor Function through the scale GMFM-88 (Gross Motor Function Measure - 88 ) and the Activity and Participation will be evaluated by the Inventory of Evaluation of Pediatric Disability (PEDI). The analysis of the results will be carried out using the Statistical Package for the Social Sciences (SPSS) using descriptive statistics for social and demographic characteristics and inferential for normality of data (test Kolmogorov-Smirnov ), mean comparison test to check for differences between the groups and measures of association through the coefficient of correlation. The level of significance of 5% will be established
