Filter by:The loss of periodontal attachment contributes to reduced masticatory performance and has a negative impact on general health.This clinical trial aims to assess the status of masticatory performance among patients with stage I, stage II, stage III and stage IV periodontitis, along with those with healthy periodontium.
This study aims to examine oral structural and functional problems in children with autism.
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.
Chewing is the process of making the food taken into the mouth as a bolus with rhythmic, coordinated, and sequential movements. To normal chewing function oral and perioral sensory integrity; adequate lip closure and intraoral pressure; intraoral bolus transport; normal structure and coordination of lips, palate, tongue, jaw joint, chewing muscles should be ensured. Problems that occur in bolus formation starting from taking food into the mouth are called chewing problems. The underlying cause of the chewing problem can be very diverse. The chewing problem can be seen in genetic, neuromuscular, gastrointestinal pediatric diseases as well as cognitive, behavioral problems or in healthy children. Many different health professionals take part in the rehabilitation of the chewing problem, but the family is at the center of the rehabilitation. For this reason, the level of knowledge, experience, and approach of the family is very important. The aim of this study is to determine the swallowing-chewing problem knowledge levels, experiences and approaches of the caregivers of the child with chewing problems.
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).
The aim of this study was to compare the MBF and chewing efficiency of complete denture bases fabricated by conventional, 3D printing and milling techniques. The research hypothesis was that, there are no significant differences in MBF and chewing efficiency in complete dentures fabricated by the three methods.
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.
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.
The study will investigate to verify whether pediatric dentists could determine chewing performance level by using Karaduman Chewing Performance Scale in children.
This study will report the chewing and swallowing disorders of a Coffin-Lowry Syndrome (CLS) patient, and effects of chewing and swallowing training on chewing and swallowing function.
