Aim of the study was to assess electrophysiologic characteristics of masticatory muscles, right and left temporalis and right and left masseter, in nasal and oronasal breathing modes. The study was conducted on the group of 30 female volunteers who were referred to the clinic for orthodontic problems. Conflict of interests was ruled out. Read More

The aim of this work is the analysis of histochemical and morphometric properties of the masseter muscles of Ctenomys talarum and Cavia aperea. The former belongs to a subterranean rodent clade, Ctenomyidae, which has evolved a robust masticatory apparatus adapted to chisel-tooth digging and processing of abrasive grasses; C. aperea belongs to the family Caviidae, with relatively graceful jaws and mandibular musculatures, consistent with less mechanically challenging diets.

Aim: To compare dental and psychological status in athletes of Olympic teams and the population of Moscow.

Materials And Methods: In order to study the features of the dental rehabilitation of Olympic athletes, a comparative study of the dental and psychological status of 132 athletes was carried out when they were included in the Olympic teams and 104 residents of Moscow of the same age. Clinical x-ray examination was supplemented by «Hamburg testing» of the masticatory apparatus and psychological examination using common questionnaires and scales. Read More

BACKGROUND Chewing dysfunction is one of the most common serious complications after a stroke. It may be influenced by the hardness of the masseter muscle and masticatory performance; however, the association between these 2 factors is not explicit. Thus, it is meaningful to explore the functional status of the masseter muscle among stroke patients. Read More
