[Indices characterizing the expression of hyperesthesia of the hard dental tissues in patients with periodontitis].

Clinical examinations of 226 patients with periodontitis have revealed in 61% of them hyperesthesia of the hard dental tissues, that was mostly generalized, characterized by a marked reaction to thermal, chemical, and tactile stimulants. Study of the mineral metabolism has demonstrated that growing bone tissue loss in dental biopsy specimens and gingival fluid is associated with reducing levels of P, Ca, and Mg. Combination of clinical manifestations of periodontitis and hyperesthesia necessitate search for combined therapy aimed at simultaneous elimination of hyperesthesia and inflammation.
