Groups of 53 patients with oral cancer and 100 controls who were attended at the Dentistry College (Córdoba, Argentina) between 2009 and 2013 were examined by trained professionals. Age, gender, body mass index, smoking, involuntary smoking, alcohol consumption, hot beverages, chronic mechanical irritation of the oral mucosa, oral potentially malignant disorders, oral candidiasis, human papillomavirus, tooth loss, illfitting dentures, diet, environmental carcinogens, arsenic in drinking water, and cancer family history were recorded. Model 1 (M1) was built with statistically significant variables, Model 2 (M2) was built with statistically significant variables not acquired through clinical examination; both were analyzed with a c2 test. Model 3 (M3) was built with statistically significant variables through multivariate logistic regression analysis. For each variable a value of a whole number corresponding to the OR was assigned. Also, for each individual a total value was obtained by the sum of registered variables. The sample was split into 2 groups according to the median of total value, which were analyzed with a c2 test.http://www.sciencedirect.com/science/article/pii/S2212440314001527Fil: Piemonte, Eduardo David.
