  1. a The initial logistic regression model was constructed with ST as dependent variable and gender, age group, occupation, use of tobacco, frequency of soft drink consumption, frequency of juice consumption, frequency of gum chewing, time since last visit to the dentist, awareness of untreated oral problems, tooth brushing frequency, mouth washing frequency and type of toothbrush used as independent variables using a backward procedure. The final logistic regression model is presented in the table with ST as dependent variable and gender, use of tobacco, consumption frequency of soft drinks, time since last visit to the dentist, awareness of untreated oral problems, mouth washing frequency and type of toothbrush used as independent variables (likelihood ratio chi-square test (12 degrees of freedom) = 158.53, p < 0.001, pseudo R-squared = 0.048)
