Abstract EN
The diagnosis of oral lichen planus (OLP) is based on clinical examination and histopathological criteria.
Noninvasive diagnostics of saliva may be considered as a confirmation of OLP diagnosis and a potential alternative to an invasive method.
The objective of the present study was to evaluate the relationship between the level of tyrosine (Tyr) as well as antioxidants like uric acid (UA) and glutathione peroxidase (GPx) activity in the saliva of patients with OLP in comparison with the control group (healthy subjects without any oral changes).
A total of 40 patients with OLP and 40 healthy volunteers were selected for the study based on the modified WHO diagnostic (clinical and histopathological) criteria.
High-performance liquid chromatography (HPLC) was performed for Tyr concentration, while GPx activity and uric acid levels were determined by a colorimetric method.
The concentrations of Tyr, UA, and GPx activity were statistically lowered in OLP patients compared to the control group.
All examined parameters correlated strongly and positively with each other.
Mean values of salivary UA concentrations differed between the groups of OLP patients (reticular and erosive forms) and controls (206.66 vs.
196.54 vs.
218.49 μmol/L, respectively, p=0.001).
A similar trend was demonstrated in salivary Tyr concentration which differed statistically between the study and control groups (0.08 vs.
0.07 vs.
0.13 μmol/L, respectively, p=0.001).
Determining of a relationship between the concentrations of Tyr, UA, and GPx activity may be useful in the prognosis of OLP.
The HPLC method may be employed, as an additional noninvasive diagnostic procedure to screen OLP patients, during the routine diagnostics of salivary biochemical parameters such as aromatic amino acids.
