Healthy teeth and the life standard

V.K. Leontiev

The notion of "life standard" started to be used by the sociologists long ago and gradually has become a generally accepted and universally admitted term that means a totality of qualities and properties (characteristics) of a personality and a society, their life, health, work, existence, nutrition, rest, environment conditions. In this way the notion of "life standard" has got two sides - inside, which depends on the personality itself, and outside that depends on the development level of the society, state, nature factors, civilization level, achieved and utilized benefits.
