Secretory phospholipase-A2 and fatty acid composition in oral reactive lesions: a cross-sectional study.

Background: Oral reactive lesions are the most common lesions of oral cavity. Phospholipases and fatty acids play key roles in the creation of inflammation by change in metabolic activities and production of lipid mediators. The aim of this study was to investigate the amount of secretory phospholipase-A2 (sPLA2) and difference of fatty acid pattern in oral reactive hyperplasia and adjacent normal appearing tissues in patients with oral reactive lesions.
