[Biochemical adaptation of the periodontium to changes in functional masticatory activity].

The activity of leucine amine peptidase, glutamate piruvate transaminase was increased and those of glutamate dehydrogenase and lactate dehydrogenase decreased locally in the region with functional traumatic overload and increased mastication activity (MA) in patients periodontium as related to that in patients with nonfunctioning link in dentition and reduced MA. ATR contents in patients with functional traumatic overload and generalized periodontitis was substantially increased as compared to those in other groups of subjects.
