Aim of the study. This study aimed at comparing the oral cavity condition and Candida prevalence in generally healthy Polish and foreign dentistry students and evaluating the relationship between Candida occurrence and the oral cavity condition. Material and methods. 79 dentistry students with no systemic diseases, aged 20–25 (mean 23.5), were examined in the present study. Two groups of examined subjects were specified: 43 Polish students (group I) and 36 foreign students (group II). Group II has been divided into subgroups: IIa – students from Taiwan and IIb – students from Europe and USA. Occurence of oral mucosa lesions, periodontal treatment needs (CPITN), caries prevalence (DMFT) and oral hygiene (OHIs) were investigated. Evaluation of Candida occurrence on the oral mucosa was included in the study. Results. Comparison of the oral cavity condition in Polish and foreign students showed no significant difference, with the exception of the number of teeth with active caries, that was significantly higher in foreign students (D 1,2) than in Polish students (D 0.4). Mean indices rates in the group I were: CPITN 0.9; PUWz 8.7; OHI-s 0.4 in the group II 1.0; 7.0; 0,5, respectively. The most commonly observed oral mucosa lesions, in both groups, were white coated tongue and buccal white line. Candida was found in 38,0% of the subjects, its prevalence was similar in both groups (I – 34.9%, II – 41.7%). No correlation between Candida occurence and oral cavity state was detected. Higher frequency of active caries in Candida carriers was the exception.

Key words: Candida, oral cavity state, dentistry students.
