[Effect of adaptation to short-term stresses on periodontal tissue resistance to acute stress].

The experiments on 53 albino Wistar rats exposed to acute stress have demonstrated that there is activation of acid proteinases at pH 5.0 and an increase in the levels of sialic acids in parodontal tissue, which is an important mechanism in the development of their destructive changes. Preadaptation to short-term stresses produces a stress-protective effect, promoting the inhibition of proteolysis and the normalization of parodontal levels of sialic acids.
