Physical indices of the oral fluid in children with caries and intact teeth at different age periods.

OBJECTIVE: Introduction: Caries occurs most frequently among dental diseases of the hard dental tissues in children. Its occurrence and intensity do not decrease, although scientists and practitioners make much efforts directed to the reduction of these indices The aim: Therefore, the objective of our study was to investigate the indices of rate salivation and viscosity of the oral fluid in children at different age periods with caries and intact teeth. PATIENTS AND METHODS: Materials and methods: 134 children, 7-9 years old, and 89 children,10-12 years old, studying at Poltava schools were examined. Dental examination was conducted according to the common methods. Caries intensity in all the children was determined by Caries Filling Extraction (CFE) Index, and CFE+cfe. To determine salivation rate the oral fluid was collected on empty stomach in the morning into sterile calibrated tubes during 5 minutes. RESULTS: Results and conclusions: Investigations of physical indices of the oral fluid in children of 7-9 and 10-12 years of age did not find their reliable difference considering the child's age. Meanwhile the indices of salivation rate and oral fluid viscosity in children with caries and without it were found to differ much. That is, the course of carious process in children is associated with reduced salivation rate and increased index of the oral fluid viscosity, which in its turn deteriorates hygienic state of the oral cavity enabling to activate the activity of dental deposit microflora and its effect on enamel demineralization followed by occurrence of carious defect of temporary and especially permanent teeth recently erupted and poorly mineralized. The results obtained were calculated by variation statistics method. The indices were considered to be reliable with small er, Cyrillic</=0,05.
