Purpose: The aim of this study was to examine the relationship between self-control and self-confidence, and students' self-rated oral health and oral-health-related behaviours. Materials and Methods: The present study sample consisted of 178 first-year medical students. The questionnaire that was used in this study included information about sociodemographic factors, behavioural factors, self-reported oral health status, self-control and self-confidence. Results: The results showed that mean levels of self-confidence in individuals with current extracted teeth and with poor/ very poor perceived gingival condition were statistically significant and lower than those with no current extracted teeth and with self-rated excellent gingival health (P 0.05). Also participants with self-reported gingival bleeding showed lower values of self-control compared with those with healthy non-bleeding gingiva (P 0.05). When oral health behaviour was evaluated, it was shown that students with higher scores of self-control were more likely to use everyday mouthrinses (P 0.05). The multiple linear regression analyses showed, for self-rated oral and gingival health status as dependent variable, a strong association with students' self-confidence level (P 0.05). Conclusions: The results support the view that self-confidence is related with oral health status, and individuals with impaired oral and gingival health have a low self-confidence level.
