| Summary: | There were studied 92 somatically healthy persons of young age (18-25 years old), with generalized periodontitis (GP) of initial-I degree of development, among them: 30 patients with chronic generalized periodontitis (CGP), who were included into group І; and 32 patients with exacerbation of the chronic generalized periodontitis (ECGP) – into group II; and 30 healthy patients. The carbohydrate metabolism indexes were studied, namely: the content of glucose, pyruvate (pyruvic acid) and lactate (lactic acid) and lactate dehydrogenase activity (LDG) in the oral liquid.
We have determined that in the presence of CGP of the initial-I degree of development, and especially in its exacerbation, there is a significant increase of indicators of carbohydrate metabolism. In young patients with CGP indicators of glucose, pyruvate, lactate and LDG activity in the oral liquid increased by 2.0, 1.34, 1.58 and 1.37 (p<0.001, p<0.01) times respectively, and in case of ECGP they grew even more: by 2.71, 1.98, 1.76 and 2.07 (p<0.001) times, respectively.
Among all the indicators, that characterize the carbohydrate metabolism, in addition to the level of pyruvate, in case of different course of GP a significant difference was revealed: in patients with ECGP compared with the data in CGP, glucose and lactate levels and LDG activity in the oral liquid were significantly higher - at 35.75% (p<0.05), 34.29% (p<0.01) and 36.59% (p<0.001) respectively.
Detected violations of carbohydrate metabolism indeces in the oral liquid indicate the involvement of these processes in the pathogenesis of GP and the necessity of their correction.
