Abstract

Aim: To measure the electric potential difference and the salivary pH level in patients with erosive and non-erosive oral lichen planus (OLP) who had two or more different dental alloys in the mouth. Methods: The study included 10 patients with erosive OLP, 22 patients with non-erosive OLP and 29 control participants without OLP. All participants needed to have at least two different dental alloys in their mouths, one of which had to be amalgam. The electric potential difference was measured using PC controlled milivoltmeter, while the salivary pH was measured using pH indicator strips. Results: The median of electrical potential difference in the group of patients with erosive OLP was 120 (45-275) mV, in patients with non-erosive OLP 153 (45-230) mV, and in control participants 140 (45-265) mV. Kruskal- Wallis test showed that there were no statistically significant differences in the electrical potential between the all tested groups (P = 0,689). Also, there was no difference in the salivary pH between the all tested groups (P = 0,322). Discussion and conclusion: The values of electric potential difference and salivary pH in the patients with erosive and non-erosive OLP are not significantly different in comparison to the values in the patients without OLP, suggesting that amalgam fillings in OLP patients should not be replaced.
