Abstract— An electronic method of recording displacement was used to study mandibular movement during mastication. The technique enables the parameters of muscle activity, the sound of tooth contact, the force developed between opposing teeth, and the displacement of the mandible to be recorded at the same time on a single U/V chart.

Characterization of the volatile fraction of mastic oil and mastic gum
Natural Product Research, 2020GC-MS of ethyl acetate solutions and HS-SPME-GC-MS of mastic oil and mastic gum showed the presence of α-pinene and β-myrcene as main components of the mixture. In the GC-MS analysis of mastic oil 19 compounds were detected, while mastic gum allowed to detect only twelve compounds.

Mastication is the first stage in the process of digestion. In most mammals, controlled vertical and transverse movements of the mandible, as well as protrusion and retrusion of the tongue characterize mastication. These controlled movements of the mandible contribute also in swallowing and production of speech. In these functions significant is also

Hemangiopericytoma of the Masticator Space
Annals of Otology, Rhinology & Laryngology, 1996Hemangiopericytomas are rare tumors of the head and neck. The benign presentation of this tumor belies its high local recurrence rate, local aggressiveness, and malignant potential. In view of these characteristics, workup to provide a diagnosis preoperatively is of significant importance. Diagnostic imaging is helpful in planning operative management,

Oral physiology and mastication
Physiology & Behavior, 2006Mastication is a sensory-motor activity aimed at the preparation of food for swallowing. It is a complex process involving activities of the facial, the elevator and suprahyoidal muscles, and the tongue. These activities result in patterns of rhythmic mandibular movements, food manipulation and the crushing of food between the teeth. Saliva facilitates

Mastication of Rubber. I. Mechanism of Plasticizing by Cold Mastication
Rubber Chemistry and Technology, 1952Abstract The process of cold mastication has been rationalized in terms of recognized chemical reactions, and its essential difference from the hot mastication process has been demonstrated. Many apparently unrelated phenomena occurring on cold mastication, as, for example, are collected in a recent survey, can be interpreted as specific ...

Mastication for the mind—The relationship between mastication and cognition in ageing and dementia
Neuroscience & Biobehavioral Reviews, 2011The 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 firmly established, and is investigated in the context of a number of different ...

Coordination of mastication and swallowing
Dysphagia, 1992The coordination of mastication, oral transport, and swallowing was examined during intake of solids and liquids in four normal subjects. Videofluorography (VFG) and electromyography (EMG) were recorded simultaneously while subjects consumed barium-impregnated foods.

Lymphomas of the Masticator Space
Archives of Otolaryngology - Head and Neck Surgery, 1976Lymphomas that involved the masticatory space occurred in three patients. In one patient, the masticator space remained the sole manifestation for many years; in the other two patients, the masticator-space involvement was a local manifestation of constitutional disease.
