| Research Abstract |
The aim of this study was to characterise haemodynamic reactions in the human masseter muscle evoked by different types of experimental jaw-muscle contractions using non-invasive method. The generally healthy subjects performed the following four standardized oral-motor tasks: (1) maximal voluntary contractions, (2) tooth grinding, (3) gum chewing, and (4) very low level but for two hours of tooth clenching task repeated for three days. The results showed that high-intensity experimental tooth clenching caused constriction-like reactions in the masseter muscle whereas rhythmic tooth grinding did not cause detectable changes in haemodynamic characteristics of masseter muscle.
