Active clinical trials for "Temporomandibular Joint Disorders"

The aim of the study was to evaluate any relation between elongated styloid process (ESP) and type of Temporomandibular Joint Disorders (TMD).

The aim of the present investigation was to perform the content and construct validation of the diagnostic criteria for TMD (DC/TMD) Axis I, for children 7 to 11 years old. A Delphi process was used to perfom the content validity of the DC/TMD Axis I. 189 7-11 years old children were assessed with the adapted instrument. Confirmatory factor analysis (CFA) was used to investigate construct validity of the DC/TMD for children. A baseline one-factor model was compared against a two-factor (Model 2) and a seven-factor (Model 3) models based on the original DC/TMD. Root-mean-squared error of approximation (RMSEA), comparative fit index (CFI), chi-square, change in chi-square and Cronbach's Alpha were used to analyze the data. All analysis were performed in STATA© version 13.0.

The aim of this study was to evaluate masticatory muscle electrical activity in post-pubertal females with forward head posture (FHP) and temporomandibular disorders (TMD) as well as in post-pubertal females with neutral head posture and with no temporomandibular disorders.

It was proposed in this study to evaluate the prevalence of TMD signs and symptoms in State University of West of Parana's dental students with natural dentition, in patients with removable partial dentures and double complete dentures.

The disorders that affect the temporomandibular joint (TMJ) are responsible for the diverse symptoms. Objective: To evaluate whether or not the relationship between signs or symptoms of TMD and presence of harmful habits. The investigators evaluated 244 adolescents enrolled in public school . The investigators used the questionnaire for selection of orofacial pain and temporomandibular disorders, recommended by American Academy of Orofacial Pain to assess the presence or absence of signs and symptoms of TMD.

The aim of this research was to determine the existence of a correlation between the degree of temporomandibular dysfunction and cervical posture in different occlusal classes in adolescents. A cross-section, observational study was carried out, in which 296 adolescents took part. For the evaluation, the patients were divided into groups according to the presence and severity of the temporomandibular dysfunction, using a questionnaire and occlusal Angle classification. The posture analysis was carried out using photogrammetry and the software Alcimage® to measure the predefined angle based on the protuberances of the Spinous Process of the 7th Cervical Vertebra (C7), Manubrium of the sternum and Mentum Vertex.

Increased life expectancy has attracted research attention, interested in provide a quality and healthy aging. According to the latest census conducted in 2010 by IBGE, Brazilian population consists of 97,342,162 women, whom estimates 30 million are between 40 and 65 years old, a period that includes the climacteric. Therefore, clinical conditions such as osteoporosis becomes significant, either from public health policy standpoint or in relation to the social aspect, by compromising life quality. Women also suffer more from temporomandibular disorders (TMD) than men, and the beginning of this situation occurs after puberty, with peaks during the reproductive and remission periods after menopause. Female sex hormones involvement in osteoporosis is well established, but their participation in the TMD is still controversial. Thus, this study aims to investigate the role of systemic bone mass in menopausal women as a risk factor for articular TMD, as well as the TMD pain behavior during menopause transition periods (48 to 55 years), postmenopausal (56-65 years) and senescence (65-70 years). Therefore, 100 women attended by the HC - FMUSP Gynecology Division, Climacteric Sector, were clinically evaluated by the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), used to obtain diagnoses and their associations, as well as to quantify the TMD pain sensitivity degree through the Craniomandibular Index (CMI), both applied by a single examiner. The bone densitometry provided bone mass data of femoral neck and lumbar spine (L1-L4). The RDC/TMD performance as a diagnostic test also was subjected to analysis, considering the 3.0 Tesla magnetic resonance imaging as reference standard, undergoing 30 women, of 100 assessed, in this imaging exam. After analyzing the results, it was shown that the risk posed by osteopenia was 1.33 (IC95% 1.20 - 1.46), with a risk increase of 0.33, while the risk of osteoporosis showed 1.39 (IC95% 1,20 - 1.23 to 1.55), increased by 0.39. Joint diagnoses predominated (68.0%), while 18.0% muscular diagnoses and 14.0% corresponds to the absence of clinically diagnosable conditions, according to the RDC/TMD. The performance of the RDC/TMD to diagnose articular DTM revealed accuracy of 68.0%, sensitivity of 83.0%, specificity 53.0%, pre-test probability of 52.0%, positive predictive value of 60.0 % and negative 74.0%, positive likelihood ratio of 1.77 and negative 0.32. As for the soreness sensibility in TMD, it was found that aging shows a clear tendency towards its reduction (A =- 4.5, p = 0.0324). Then, the study concluded that the decrease in female sex hormones, peculiar to aging, increases the risk of articular TMD, although this pain disfunction decreases with age. The RDC/TMD can be used for large populations screening, but its indication in clinical practice should be done with caution.

The present study aims to verify the reliability of intra and inter-examiner of angular measures proposed by SAPO postural assessment software. Methods: 24 subjects were photographed and three experienced examiners analyzed the images.

This study provides a mechanism for evaluating patients for possible participation in NIDCR clinical research studies. NIDCR studies involve three major areas-pain, neurosensory mechanisms, and pain-relieving drugs-all of which have specific requirements and patient characteristics. No treatment is offered under this protocol; it is intended to facilitate patient recruitment into NIDCR studies. Patients with unusual or unknown conditions that have or have not been diagnosed may be eligible for this screening study. Specific medical criteria for enrollment vary with the particular protocol for which the individual is being screened. Medical and dental histories will be obtained and participants will have a dental examination. Diagnostic procedures will be done in accord with standard medical and dental practice and may include X-rays, blood tests, and routine urinalysis, as appropriate. Participants found eligible for an active study may enroll in that study. Those who are not eligible for a current study may be re-evaluated for future studies within a year if they wish. After 1 year, participants for whom no appropriate studies are identified will be referred back to their primary doctor or referring physician or dentist.
