Mathematical modeling of oral hygiene in children with cerebral palsy depending on the degree of severity of motor impairment and electroneuromyography parameters

Abstract

Introduction. Examination of the dental status of children with cerebral palsy (CP) is indicative of a high occurrence and intensity of lesions of the hard dental and periodontal tissues. One of the leading etiopathogenic factors promoting the development of major dental diseases among these children is an unsatisfactory oral hygiene. Objective: to design a mathematical model to predict the state of oral hygiene in children suffering from CP with various degrees of severity of the underlying disease. Materials and methods. 122 children (average age 8.8±3.7 years) with spastic forms of CP were examined. The state of oral hygiene and intensity of dental caries were determined in all children. Electoneuromyography (ENMG) was conducted for all of them with CP, by means of stimulation methods. Results and discussion. Stomatological examination of children demonstrated a certain tendency of caries intensity increase and deterioration of oral hygiene with increasing the degree of motor function impairments. ENMG examination of patients with CP found neurophysiological signs of supra-segmental disorders, correlated with the degree of motor function impairments. The mathematical model was developed on the basis of the data obtained, enabling to prognosticate the degree of oral hygiene depending on ENMG parameters. Conclusions. The mathematical prognostic model developed enables to prognosticate oral hygiene state in every particular case, on the basis of ENMG examination carried out in the neurological department during general medical examination of children, thus laying the bases for differential indication of preventive measures and optimal direction of appropriate recommendations for both parents and children.
