Multivariate regression analysis with stepwise insertion method to compare bleeding events with age, gender, VKA, DOAC, degree of gingival inflammation, granulation tissue, and multi-single-rooted elements. Gingival inflammation, registered as absent, mild, present, and severe, was grouped in dichotomic way (absent and mild, as absent and present, and severe as present) for statistical purposes
