Introduction/Objective. Aggressive periodontitis (AP) is a progressive
disease that leads damage to periodontal tissues. The aim of the study was
the analysis of intracellular enzymes: aspartate aminotransferase (AST),
alanine aminotransferase (ALT), alkaline phosphatase (ALP), acid phosphatase
(ACP) and electrolytes in the saliva of patients with AP and their
correlation with clinical parameters before and after the therapy. Methods.
The study included 30 patients with AP (experimental group) and 35 patients
with healthy parodontium (control group). Intracellular enzymes and
electrolytes were analyzed in an unstimulated saliva of subjects with AP,
before and after the therapy and in saliva of the control group. The analysis
of biochemical markers was carried out using kinetic methods with commercial
reagents. Results. Concentrations of the biochemical markers AST (28.18 ?
25.16), ALT (5.48 ? 5.14), ALP (31.13 ? 37.79), ACP (17.53 ? 14.77), calcium
(2.80 ? 1.97), phosphate (4.43 ? 1.92) in the saliva of subjects of the
experimental group were statistically significantly higher in relation to the
control group (p = 0.000; p = 0.001). Significant correlation was found
between AST values, debris index (? = -0.444; p = 0.026) and calculus index
(? = -0.513; p = 0.009), and between the plaque index and ALP level in the
saliva after therapy (p = 0.020). Conclusion. The investigation will
contribute to a better understanding and standardization of biomarkers in the
saliva that mayhelp in diagnosing the AP and evaluation of the applied
therapy.
