[Local homeostasis and acid-based balance in the oral cavity in patients with diabetes mellitus II].

60 patients were researched for the purpose of comparable estimation of local homeostasis' indexes and acid-based balance in the oral cavity. They were divided into three groups: patients with parodontitis and diabetes (second type), patients with parodontitis only and practically healthy patients. Their blood was analyzed for glucose and glycerinated hemoglobin, mixed saliva--for the presence of glucose with use of the new method, salivation speed, bacterial composition of lingual plaque and parodontal pockets, pH of mixed of saliva, pH of lingual plaque and gingival liquor, carbamyde pH-test index. Patients with diabetes showed an increase of glucose concentration in the saliva which correlates with similar index of blood, as well as abrupt reduction of salivation and disorder of micrbiocenosis. An increase of acidosis in oral cavity and parodontal tissues, an increase of the activity of ureazpositive micro flora in lingual plaque were discovered. For express diagnosis of disbacteriosis in oral cavity the authors recommend to use indexes of local carbamyde pH-test on the tip of tongue and the new non-invasive hyperglycemia diagnosis method.
