Oral health care frequency of dental students and non-dental students before and after the course. a, b Dental and non-dental students improved greatly in toothbrushing and interproximal cleaning after the OHE-related course. c, d Dental students surpassed non-dental students in toothbrushing (P = 0.004) and flossing (P = 0.000) before and after the course. Non-dental students were more willing to use toothpicks after the course (P = 0.016). (Wilcoxon signed-rank test; ****, P = 0.000; **, P = 0.01; *, P < 0.05)
