Experemental prevention of stress changes of tooth pulp tissues and periodontium with nitric oxide donor molecules

The research results of influence of donors and anzyme blocker NO-synthesis on morphological state of tooth pulp and periodontium tissues at stress influence on laboratory animals are presented in the article. It is revealed, that nitric oxide donor molecule L-arginine is able to limit the development of stressreaction and decrease quantity of morphofunctional infrigements in periodontium tissues and teeth stump. Enzyme blocker NO-synthesis LNNA helps to strengthen alternating effects of stress reaction in periodontium tissue and teeth pulp.
