Filter by:Temporomandibular Disorders (TMD) encompass various conditions that affect the temporomandibular joint and associated tissues, often causing or being associated with other symptoms such as jaw pain, myofascial pain, neck pain, and headaches. TMDs are classified according to the DC/TMD instrument in which the joint and pain axes are evaluated. However, there is no evaluation of mandibular function, and TMDs can result in a decrease in jaw strength and resistance. This leads to an increase in the chewing fatigue. Reliable and time-effective diagnostic methods for evaluating masticatory function are crucial in the clinical setting because of the high prevalence of TMD. Chewing efficiency is essential for food preparation and nutrient absorption, and muscle fatigue is a common problem affecting chewing ability. Despite this, there is a lack of validated tests to evaluate chewing fatigue in patients with TMD, which makes its consideration unnoticed in clinical practice. The modified six-minute functional chewing test (F-6MMT) was proposed as a tool to evaluate chewing ability and fatigue in patients with TMD. This test is an adaptation of a previously designed test in which subjects with mitochondrial pathology were evaluated; however, the subjects were not instructed to perform functional chewing during the test. In this version, modifications are added so that the test is as functional as possible, allowing chewing to be evaluated in a standardized way, and cut-off points established between healthy subjects and subjects with TMD in terms of chewing capacity in general and fatigue in particular. This study will follow standardized reporting guidelines and recruit participants from diverse clinical settings.
the goal of this clinical trial To evaluate the effects of different base materials of mandibular implant supported overdenture with bar/clip attachment on masticatory efficacy. Twenty-four edentulous patients were selected to place two inter-foraminal mandibular implants with custom-made cast bar to retain overdentures made from two different base material and divided into two groups. The masticatory efficiency were tested using three different food categories (carrots, bananas, and apples) and measured by four parameters.
Background: Obesity is considered an epidemic disease of great repercussion on the world and its prevalence has increased in recent decades. The treatment of obesity aims to improve health and quality of life, by reducing body weight. The clinical approach to obesity is routinely the first line of treatment. Clinical treatment usually involves a combination of restriction of caloric intake, modification of behavior and habits, regular practice of physical activity and pharmacotherapy. Clinical treatment of obesity leads to considerable weight loss, but often not sustained in most patients. This long-term sustained weight loss is an attribute of bariatric surgery, since severe obesity remains largely refractory to dietary and drug therapy. Changes in lifestyle that occur in severely obese patients undergoing bariatric surgery, especially in terms of food, lead to the need for the contribution of speech therapy to adapt to the new way of ingesting food. Objectives: to analyze the stomatognathic functions of mastication and swallowing and to verify the effectiveness of orofacial motricity stimulation in adults, severely obese before and after bariatric surgery. Methods: This is a randomized, controlled clinical trial involving severely obese adult patients of both sexes referred for bariatric surgery. This study was approved by the Research Ethics Committee of the Centro Universitário Fundação Assis Gurgacz (FAG) in the city of Cascavel (PR), Brazil, protocol number CEP FAG no. 4,169,295. Patients will be consecutively recruited from the Bariatric Surgery Department of Hospital São Lucas (FAG) and referred to the Speech Therapy Clinic according to the eligibility criteria of the research protocol. After the initial assessment, patients will be randomly assigned to an intervention group (MOG) and a control group (COG). The COG and MOG groups will be evaluated before and after bariatric surgery. Only the GMO will be submitted to the speech therapy training program before bariatric surgery. The myofunctional characteristics will be evaluated through the Orofacial Myofunctional Assessment protocol with Scores (AMIOFE). The AMIOFE protocol was designed according to the assessment models that reflect the physical characteristics and orofacial behaviors of individuals. In this way, the components and functions of the stomatognathic system will be evaluated in terms of appearance/posture, mobility and swallowing functions - liquid and solid - chewing and breathing.
This clinical trial demonstrates prosthetic management of patients complained from lack of satisfaction and function of maxillary conventional complete denture as a result of severe maxillary ridge resorption seeking for fixed restoration. They were attended to the Department of Prosthodontics, Faculty of Dentistry, Mansoura University (Mansoura, Egypt). They demonstrated sever bone loss especially in the posterior region which complicate conventional implant placement for full arch prosthesis. Eight PEEK sub-periosteal implants were surgically placed. Probing depth was measured after three & six months from sub-periosteal implant placement. Tumor necrosis factor-alpha (TNF-α) & Interleukin-8(IL-8) Peri-abutment cervicular fluid were measured one month, three months , six months & one year from sub-periosteal implant placement. Clinical & Radiographic examination (CBCT) was done two years after sub-periosteal implant placement.
The main aim of this cross-over intervention study is to assess the effect of masticatory side-switch frequency on different aspects of masticatory function, including masticatory mixing ability and rhythm. A secondary aim is to explore the subjective perception of taste, muscular fatigue, and saliva production through a VAS. Thirty-six volunteers recruited for convenience, among students of the Degree of Dentistry of the Faculty of Medicine and Health Sciences of the University of Barcelona, will perform 6 tests, each consisting of 2 assays, chewing a two-coloured chewing gum, during 40 masticatory cycles. The tests will be randomised masticatory sequences of "free-style", "unilateral-right", "unilateral-left", switching the chewing side at 5% "G05", at 15% "G15" and at 25% "G25". Video recordings of these tests will be made to later assess, on slow playback, the change of the chewing side and the masticatory rhythm. The masticatory mixing ability will be determined through the scanning and posterior analysis of the red-channel in the histogram plug-in in "ImageJ" (R).
From the change in self-regulation, memory is inhibited, allowing individuals to suppress or ignore unwanted or outdated associations and thus help to filter information relevant to dietary goals from irrelevant information. Provoking changes in neuroplasticity and cortical excitability contribute to the regulation of neural activity. Both could be modified by applying direct electrical current to the sensorimotor cortex, with polarity/current-dependent results, and their effect would last for hours after the end of stimulation. Transcranial Direct Current Stimulation (tDCS), translated into Portuguese as Estimulação Transcraniana por Corrente Contínua (ETCC) is a neuromodulating tool in which a low-intensity electrical current is applied to the scalp to modulate neuronal activity.
This study aims to evaluate the association of masticatory efficiency with different conditions of the stomatognathic system (transitioning from primary to secondary dentition, dental caries, malocclusion, tooth loss, prosthodontic treatment) in the paediatric population. Also, to assess the correlation between masticatory efficiency and nutritional status. The study will be conducted on children between 3 and 14 years of age. Masticatory efficiency will be evaluated by the optical scanning method. Participants will chew a standardized silicone tablet controlled by the examiner for 20 masticatory strokes. By scanning the comminuted particles, data on each particle's size will be obtained. Enhanced masticatory performance is presented by a decrease in the chewed particle areas and an increase in the number of chewed particles.
The primary objective of this study is to establish the effect of the frequency of masticatory side switches on masticatory performance. We also want to know the effect of the frequency of masticatory side switches on the masticatory rhythm. Twenty-eight healthy volunteers will undertake masticatory tests, following a series of instructions given at the moment. These volunteers will take a re-test in two-weeks time. The sequence of these tests will be randomized in such a way that, each participant will initially perform an established sequence of "freestyle, only-right, and only-left" masticatory tests, and then will carry out one of the 6 possible combinations of "A1, A3, and A5". These tests will be recorded on video to assess, on slow playback, the change of the chewing side, and the masticatory rhythm.Masticatory performance will be determined by sieving the silicone particles.
Stroke affects the vital activities of daily living such as breathing and swallowing. After stroke excursion of the diaphragm reduces about 50%, and also the maximum expiratory pressure of the individual 50% or higher. Dysphagia occurs in 29% to 45% of the acute stroke cases.
Today in elderly tooth loss and loss of oral function is widespread, but it is an underexplored modifiable risk factor potentially contributing to the development of dementia. In this interventional study a "cause-effect" relationship between mastication and cognition in humans will be investigated. A total of eighty (80) participants, 65-80 years of age, indicated for prosthodontic rehabilitation will be randomly assigned to either the experimental or the control group. Participants will be randomized into two different groups, measurements are going to be conducted before and after prosthetic rehabilitation. The difference between the two groups is that the control group are going to do two measurements before undergoing the rehabilitation, this to control for the test-re-test effect. The aim with this study is to determine if the rehabilitation of chewing function will cause changes in the neurocognitive assessments of episodic memory and learning.
