Fatty acids in different subtypes of oral hyperplastic tissues. Comparison of monounsaturated and n−3 polyunsaturated fatty acids observed according the type of oral reactive lesion and biopsied tissue sample by an analysis of variance test. IFH inflammatory fibroepithelial hyperplasia (n = 24), IF irritation fibroma (n = 10), PG pyogenic granuloma (n = 6), PGCG peripheral giant cell lesion (n = 5). Different letters above columns indicate significant differences among subtypes of oral hyperplastic tissues (p < 0.05)
