Prevalence of children’s cerebral paralysis makes 3–5 children on 1000 newborns according to literature. Information on treatment of dentoalveolar anomalies at children with cerebral spastic infantile paralysis has not enough and especially about correction of myofunctional violations of chewing and facial muscles. Research of actually chewing and temporal muscle from both sides by means of a two-channel electromyograph “M-test neuro” for measuring bioelectric potential of these muscles at children with cerebral spastic infantile paralysis and dentoalveolar anomalies is carried out.
The purpose of the research. To study a myofunctional condition of chewing muscles at children with cerebral spastic infantile paralysis and dentoalveolar anomalies in a mixed dentition.
Materials and methods. Research is carried out at 59 children of 6–10 years who were divided into three grous: the main group — children with cerebral spastic infantile paralysis and dentoalveolar anomalies, group of comparison — children with dentoalveolar anomalies without concomitant pathology and control group — children with a physiological bite without concomitant pathology. Each examined patient was examined chewing and temporal muscles from both sides at quiescent is carried out, at the maximum compression of jaws during 5 sec and at the maximum compression of standard cotton dental roller during 5 sec. Research was carried out by means of a two-channel elektromyograph, surface electrodes were fixed by an adhesive plaster at distance of 20 mm.
Conclusions. Electromyography of a functional condition of chewing muscles showed that biopotential at quiescent had the highest indicators of amplitudes at children with cerebral spastic infantile paralysis and dentoalveolar anomalies, and at children with a physiological occlusion — the lowest one. At compression of jaws indicators biopotentials chewing muscles considerably surpassed at children with a physiological occlusion than in those with cerebral spastic infantile paralysis and dentoalveolar anomalies.
