Multivariate logistic regression analysis of the influence of the explanatory variables age, gender, teeth number and endodontic status (0, patients without root-filled teeth; 1, patients with one or more root-filled teeth) on the dependent variable ‘periapical status’ [0, apical periodontitis (AP) absent; 1, patients with one or more teeth with AP]
