Oral cavity homeostasis plays an important role in formation of caries-resistant enamel. Significant incidence and intensity of temporary and permanent caries in children is due to biochemical and biophysical parameters of mixed saliva, whose stability, both quantitative and qualitative, is essential for normal functioning of hard dental tissues. Oral fluid, whose remineralizing ability has been proved by a large number of studies, plays an important role in maintaining oral cavity homeostasis. Salivary flow rate is very important. Salivation reduction causes aggravation of oral cavity hygienic condition, which in turn, leads to development of caries. Therefore, our research objective was to study salivary flow rate in children with different dental statuses. Children with intact teeth have medium salivary flow rate which refers to normal salivation (0,42±0,009 ml/min). In children with caries of temporary and permanent teeth this value is 0.35±0.006 ml/min, which is within normal, but values are much lower than in children without caries (р<0,001). No age differences in the parameter have been found. It is important to determine risk factors in children with carious permanent teeth. Their salivary flow rate in all age groups is lower than in children with intact permanent teeth. This is also true for comparing children with carious temporary teeth and intact temporary teeth. Children with carious temporary teeth had a lower salivary flow rate compared to children without caries in every age group (р<0,05). However, the values are within normal. A study of caries activity in children and its comparison with salivary flow rate is very indicative in the meaning of caries interconnection with salivary flow rate. In 7-year-olds without caries, the average salivary flow rate is 0,41±0,01 ml/min, which refers to normal salivation. With subcompensated and decompensated forms of caries activity, salivation probably gets lower compared to children with intact teeth (р˂0,001). Numeric values are within normal with subcompensated level and refer to hyposalivation with decompensated level (р˂0,05). Salivary flow rate in children without caries in all age periods is probably higher than that in children with carious teeth. No age differences in the parameter in question have been found. As the number of carious teeth in the oral cavity increases, salivary flow rate drops, but it is always within normal. Hyposalivation was found in 7-year-olds with decompensated level of caries activity. Therefore, children with low salivary flow rate require preventive measures aimed to regulate this process in order to reduce caries attack rate.
