The analysis included also evaluation of negative health habits of respondents resulting in dental diseases and afflict damage to teeth and oral cavity. It was found that more than half of respondents had higher education. They consider themselves as financially secure, they did not smoke and had good condition of oral cavity. They choose dentists according recommendation of friends and seek dental care only in case of obvious signs of disease. The analysis of possible reasons for seeking dental professional revealed that 75.5% of respondents seek dental care when there are "obvious signs of disease and deterioration of health", 21.2% "when first signs of disease occurred" and 3.3% "only in critical situation".
