BACKGROUND Bacterial plaque control plays a key role in the prevention of caries and periodontal diseases. Hygiene negligence in this respect may influence the state of gingiva, and - in the long term - the number of lost teeth. The recommended method of mechanical control of dental plaque is tooth brushing twice a day. OBJECTIVES The aim of the study was to assess the frequency of tooth brushing, the use of various oral hygiene accessories, the number of preserved teeth, and the occurrence of gingival bleeding in adult Poles, based on a questionnaire study. MATERIAL AND METHODS The prepared questionnaire consisted of a general part, assessing the socioeconomic and general medical status of respondents, as well as of specific questions about behavioral actions related to oral hygiene. The study was conducted in 10 Polish cities in Mobile Medical Units as part of the "Health First" campaign in 2017. RESULTS The study included 713 respondents: 447 females and 264 males at an average age of 51.1 ±17.6 years. During the previous 6 months, 448 females and 265 males had visited the dentist. The average number of teeth among the respondents aged 35-44 years was 27, and for subjects >65 years old -13. There were statistically significant differences in the frequency of tooth brushing depending on sex and place of residence. The respondents used manual soft and medium toothbrushes more often than electric brushes (p < 0.05). Inhabitants of larger cities, compared to rural residents, used dental floss and toothpicks more frequently (p < 0.05). In total, 271 (50%) of the respondents reported gingival bleeding during tooth brushing. There was a statistically significant association of gingival bleeding with genetic load, and with the use of a manual soft toothbrush and mouthwash. CONCLUSIONS Pro-health behaviors of adult Poles in maintaining optimal oral hygiene are unsatisfactory and need improvement.
