Flowchart of the study. Mice received either none or administrations of low (3 nmol) or high (24 nmol) concentrations of the co-carcinogenic substance dibenzo(a)pyrene (DBP) into the oral cavity three times per week over the entire study period of 12 months. The DBP administration was paralleled by a monthly treatment of the right cheek with either UV (ultraviolet) 8 s, UV 48 s, kINPen plasma 10 s, kINPen plasma 60 s, or MWM plasma 10 s across the period of 12 months. After sacrifice, sampling of tissue for downstream analyses was performed. Each group contained 19–26 animals.
