The purpose of this study was to use the oral health impact profile (OHIP-14) to evaluate the impact of oral health on the quality of life in a sample of Czech population. The study sample consisted of 684 partici-pants aged 30-69. Statistical analyses was performed using Mann-Whitney, Kolgomorov-Smirnov or Krus-kal-Wallis test. Internal reliability for the 14 items overall was very high (Cronbach's alfa = 0,92). The most frequently mentioned impact of oral health on quality of life (answers fairly often and very often during last 12 months) were „Uncomfortable to eať" (9,5 %) and „Painful aching" (9,2 %). The study refered to the attitudes of res-pondents to their own oral health level including aesthetic aspects and effect of previous therapy. Know-ledge of these data seems to be important for the formulation of health care needs and their financial sup¬port, evaluation of treatment efficacy, and creation of health care programs. It can even identify oral diseases and disturbances which patients interpret as the most serious oral problems requiring dentisťs intervention.
