Influence of carcinogenesis in the oral cavity on the level of some bioelements in the saliva

The aim of this study was the examination of influence the oncogenesis process of oral cavity on the level of some bioelements (Ca, Mg, K, Na, Zn, Cu, Mn, Fe) in the saliva. The saliva was sourced from patients with oral cancer (carcinoma planoepitheliale spinocellulare keratodes and akeratodes: mucosae buccae, fundi oris, linguae, palati molli). The determination of the analyzed elements were made by atomic absorption spectrophotometry method. The levels of most of the analyzed elements (Ca, Mg, Na, Zn, Cu, Mn and Fe) were significantly higher in the case grop comparing to controls.
