Indicates of structured-functional resistance of the enamel are diametrically opposite with im­portance of the intensities of the caries. If beside examined persons with high structured-function­al enamel's resistance index of intensities of the caries has at the average formed 4,22±0,41 then beside persons with very low cariesresistance -7,82±0,64. Full recovering the area after action of acid to enamel surface occurred in relatively short periods that is indicative of high level enamel resistance.
