Abstract. Caries is the most widespread dental disease among children and adolescents. Its activity is determined by the number of affected teeth. An important role after teething is taken by oral fluid, which directly affects the resistance of sound tooth tissues. Therefore, the aim of our study was to examine the rate of salivation and oral fluid viscosity among adolescents of different ages who study in different educational institutions and have different stages of caries activity. We supervised 540 teenagers who studied at schools, colleges, universities in the city of Chernivtsi. The average rate of caries in each age group was calculated for determination of caries activity stage. The rate of salivation and viscosity of oral fluid were also studied. Statistical data processing was performed by the method of variation statistics considering Student’s criterion. The average salivation rate in schoolchildren of 15-16 years old with a compensated caries activity stage was within the physiological norm. A significant dependence of salivation parameter on the stage of caries activity in 15-16 years-old. adolescents wich were studying in college was found. 16-years-old college students demostrated worse results than the schoolchildren. The salivation rate decreases in adolescents of 17-18 years-old with a subcompensated stage of caries activity comparing to the compensated stage and reaches minimum values in the decompensated form of caries. This is also applicable to the viscosity parameter of oral fluid, which increases in all age periods from I to III groups, especially at the age of 17-18 years in college students. Considering the obtained results, we can conclude that teeth caries is followed by deterioration of salivation rate and viscosity of oral fluid. In our case it is important to investigate adolescents of the same age but different education forms. The highest rates are found in college students even when comparing the same levels of caries activity and require more profound research of reasons that lead to this, which is the prospect of our further research.
