[The role of natural medicinal factors in federal and regional recreational zones in the rehabilitation of patients following surgical treatment of pathological periapical tissues and oral cavity phlegmonas].

The necessity of considering the problem with which this paper is concerned arises from the current scientific discussion of the actions of physicians working in municipal healthcare facilities and sanatoria directed toward rehabilitation of patients after surgical treatment of periapical tissues and oral cavity phlegmonas. The study elucidated the mechanism of action of mineral waters (alkaline, sodium hydrocarbonate or boron-containing water with elevated fluorine and chlorine content) extracted from natural deposits of the Belgorod Region and Krasnodar Krai (Territory). It was shown that drinking these waters contributed to the correction of the disturbed balance in the ratio of sodium and potassium ions excreted with urine and to the positive dynamics of serum phosphorus level in the patients included in this study.
