Purpose proper chewing and swallowing functions have great importance in general health, since it potentially affects food's digestion and the subject's nutritional status. The aim was to assess the validity and reliability of the self-applied Quality of Masticatory Function Questionnaire (QMFQ) in a convenience (non-referred) sample of Brazilian adolescents divided into three groups: control (...

Mastication is a forest fuel thinning treatment that involves chipping or shredding small trees and shrubs and depositing the material across the forest floor. By decreasing forest density mastication has been shown to lessen crown fire hazard, yet other impacts have only recently started to be studied. Our study evaluates how mastication treatments alter the density and composition of soil see...

A robotic device is proposed by means of which the mastication process could be reproduced in a mechanically controllable way whilst the masticatory efficiency and/or food dynamics are assessed quantitatively. A robotic model of the mastication system is developed according to biomechanical findings about the jaw structure and muscles of mastication, where each of the major muscles are, tempora...

Oral forces applied to human teeth during biting and mastication are normally described in the literature only in terms of their axial components. The purpose of this study was to fully determine the spatial characteristics of the oral resultant force - its normal and tangential components - for a given individual. A load cell was especially manufactured to measure oral force and was temporaril...

Unlike all other primates, the digastric muscle of the orangutan lacks an anterior belly; the posterior belly, while present, inserts directly onto the mandible. To understand the functional consequences of this morphologic novelty, the EMG activity patterns of the digastric muscle and other potential mandibular depressors were studied in a gibbon and an orangutan. The results suggest a signifi...

UNLABELLED Mouth breathing has been associated with severe impact on the development of the stomatognathic system. AIM This paper aims to analyze the electromyographical findings and patterns of electrical activity of the anterior temporal and masseter muscles in mouth and nasal breathing children. MATERIAL AND METHOD The patients were divided into two groups: mouth breathers (n=17) and nas...

Epulis is a benign neoplasms of the oral cavity, derived from the periodontal ligament or connective tissue, occur commonly in dogs and rare in cats. However, it is very rare in horse. The tumor can be very large to interfere with normal mastication. Several forms of epulides can histologically be distinguished in dogs. Fibromatous epulis microscopically characterized by a dense well vasculariz...

Exposure to chronic stress induces various physical and mental effects that may ultimately lead to disease. Stress-related disease has become a global health problem. Mastication (chewing) is an effective behavior for coping with stress, likely due to the alterations chewing causes in the activity of the hypothalamic-pituitary-adrenal axis and autonomic nervous system. Mastication under stressf...

Pungency is an interesting sensory stimulus analyzed from different perspectives, in particular the underpinning mechanisms of its sensation and perception. In this study, grilled pork meat coated with three types hot sauces were investigated regarding main food oral processing characteristics evaluated using time-intensity temporal dominance pungency sensations methods analyzing descriptors in...

Mastication is the process of mechanically crushing food to form soft particles, facilitating theingestion in providing nutrients body. One objectively assessed mastication functions ismastication performance. The number tooth losses one factor that affects performance; moretooth loss, lower Posterior teeth play an important role function,and loss posterior decreases research aims determine ass...
