Filter by: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.
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.
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.
This study examined the effect of Functional Chewing Training(FuCT) on tongue thrust and drooling in children with cerebral palsy.
The cause of temporomandibular joint disorders remains unknown. It is considered multifactorial and includes physical (peripheral) and psychosocial (central) factors. It has been showed an association: a steeper condylar path, flatter lateral anterior guidance, and habitual chewing on the symptomatic side. This finding argues the possibility of causation of some of these characteristics. This double blind longitudinal study aims to assess if the presence of one habitual chewing side could contribute to temporomandibular joint disorders over time. Method. Young adults with no signs or symptoms of TMD will be assessed. Participants with one chewing side (observed and interview); with steeper condylar path and lower lateral guidance angles will be considered consistent one side chewers, and this side will be considered more susceptible to suffer TMD. Mouth opening, hemispheric dominance and hemimandibular retrognathia will be considered as secondary pre-specified outcomes. Four years later, both TMJs of each participant presenting signs and/or symptoms will be evaluated according to DC/TMD.
The family has a primary prescription in the identification of the chewing disorder in children to plan appropriate rehabilitation program and implementation of the training. Therefore, it is very important to investigate the validity and reliability of classification systems that can be applied by parents. The purpose of this study is to determine the validity and reliability of the reliability and validity of family report chewing evaluation.
We aimed to evaluate chewing function (CF) in children with neuromuscular disorders, and investigate reliability of the Karaduman Chewing Performance Scale (KCPS).
