Abstract:
In experiments on 190 adult male Wistar rats it was established that at chronic stress (the congested housing of animals during 3 months) the status of marginal periodontal tissues and hard dental tissues (degree of gum recession, atrophy of alveolar bone, teeth mobility; enamel acid resistance) depended upon the organism thyroid status: hypothyroidism (intragastric introduction of mercazolil in the of 12 mg/kg body weight during 14 days, then in half dose up to the end of the experiment) increased intensity of stress disturbances whereas small L-thyroxin doses (5-8 μg/kg body weight intragastrally during 28 days after that in half dose) essentially limited them.
