Herediana [online]. 2019, vol.29, n.2, pp.137-145. ISSN 1019-4355.  http://dx.doi.org/https://doi.org/10.20453/reh.v29i2.3530.

Objective: To compare those levels enzyme of lactate dehydrogenase (LDH) in the saliva according to the condition periodontal. Material and methods: Descriptive, cross-sectional study. It was included 40 patients between 23 and 73 years, of a clinic specializing in dentistry. There were 10 patients in each group: one control (periodontally healthy) and three study. Not stimulated saliva samples (2 ml) were collected in vials for sample of sputum, directly from the mouth; they moved to 2 ml Eppendorf tubes and centrifuged at 300 rpm for 10 minutes. To assess enzymatic activity, they were placed in the automatic Analyzer “Vitalab Selectra II” (life science, the Netherlands) with reagents LDH-P UV AA liquid for serum or plasma samples. The dinucleotide of NICOTINAMIDE and adenine (NADH) consumed, was directly proportional to the activity of LDH in the saliva samples. The data were analyzed with post hoc Bonferroni-Dunn and Kruskal-Wallis tests. Results: It was found significant differences in the levels of LDH among patients with generalized chronic periodontitis versus periodontally healthy and in phase of maintenance (p<0.01). Also there was difference significant (p= 0.006) between the values of LDH of them patients with localized chronic periodontitis and the periodontally healthy. Conclusions: Enzyme LDH levels are decreased in patients during periodontal maintenance in respect to patients that have generalized chronic periodontitis, also these values are very close to periodontally healthy patients and localized chronic periodontitis.
