Sažetak:
Latencies of the inhibitory reflex (silent period) in jaw elevator muscles were electromyographicaly examined in 62 subjects with natural teeth and in 30 complete denture wearers (periodontal receptors missing). SPs were eliciting during ten subsequent open-close-clench sycles (from the position of open mouth subject closes jaws firmly and the teeth come into occlusal contact) for each individual. The new EMGA-1 configuration and Medwin software enabled exact measurement of such short reflex appearances. Latencies in individuals with periodontal inervation varied from 12.54-12.97 ms. In individuals without periodontal inervation latencies were significantly longer and varied from 16.46-17.27 ms, dependent on the examined muscle. Longer latencies i individuals with complete dentures could be attributed to the time needed for the denture to shift and elecit oral mucous membrane and/or more synapses (or a longer conduction time) from the oral mucous receptors to the nucleus motorius n. trigemini than from the periodontal receptors. Altlhough complete denture werers exhibit similar patterns of muscle activity to the individuals with natural dentition, it is obvious that reflex reaction time is longer without periodontal resceptors.
