411 Editorial T he evolution of new dental technologies, such as three-dimensional (3D) image manipulation, computer-aided design/computer-assisted manufacture (CAD/CAM), and new ceramics, are having a profound impact on treatment planning in oral rehabilitation. Yet the fundamentals of mastication, which are crucial determinants of optimizing treatment outcomes, are often overlooked. The impor...

e goal of this literature review has been to investigate the relationship between mastication and cognition, with a special focus on ageing and dementia, and its possible underlying mechanisms. Since the relationship between mastication and cognition is not yet rmly established, and is investigated in the context of a number of di erent disciplines, a comprehensive overview will contribute to o...

A regional assessment of the ecological effects of chipping and mastication fuels reduction and forest restoration treatments. Project Title: A regional assessment of the ecological effects of chipping and mastication fuels reduction and forest restoration treatments. ABSTRACT: Over the past several years, fire managers have increased their use of mastication treatments, the on-site disposal of...

PURPOSE The objective of this study was to determine whether elevator and depressor muscle activity during 5 minutes of mastication is affected by the presence of a prosthetic appliance in elderly patients. MATERIALS AND METHODS Thirty edentulous subjects (EG) and 30 age-matched dentate subjects (DG) were studied. Surface electromyographic (EMG) recordings were obtained from the anterior temp...

This paper describes and documents investigatory work for the detection and measurement of sheep rumination and mastication time periods from jaw sounds transmitted through the skull. The rumination and mastication time periods were determined by a neural network classifier using a combination of time and frequency domain features extracted from successive 10 second acoustic signal lengths. It ...

OBJECTIVE To assess the impact of aging on masticatory muscle function according to changes in hardness of solid food. METHODS Each of fifteen healthy elderly and young people were selected. Subjects were asked to consume cooked rice, which was processed using the guidelines of the Universal Design Foods concept for elderly people (Japan Care Food Conference 2012). The properties of each cook...

The study of jaw movement in humans is a primary source of information about the relationship between voluntary movement and more primitive motor functions. This study focused on the geometric form of the velocity function, as measured by linear voltage displacement transducer. Movement amplitudes, maximum velocities and durations were greater in mastication than in speech. Nevertheless, there ...
