How many were not? What correlations were there between things when that was factored in? Since tobacco is a leading cause of OSCC, what makes the researchers believe that perio (measured as bone loss) and NOT the current or previous use of tobacco was the causative factor? There is some significant bias in how this was reported, but of course it has now virally spread all over web sties potentially misleading the public as to what is a valid risk factor and what is not. People that engage in one risk factor likely have other lifestyle risk factor issues. People who eat fatty foods and have poor diets also do not engage in exercise and have corresponding collateral issues health issues, just as smokers who are obviously less health conscious likely have more perio disease. Tracking this back to the statement that -perio equals bone loss equals development of the cascade of events that causes OSCC- looks like junk science with poor bias controls stated.
