Values are given as n (%) or mean ± standard deviation.
P-values were calculated using the chi-square test (sex, birth country and smoking habits) or the Independent t-test (the remaining variables). P values in bold denote statistical significance (P < 0.05).
DMFT, decayed, missing and filled teeth; NRS, numerical rating scale; PI, plaque index.
