RESUMEN
AIM: The aim of the study was to measure the efficiency of printed health education matters with reference to caries prevention and the endurance of knowledge acquired. MATERIAL AND METHODS: The study included 74 parents of children coming from three kindergartens in the town of Plovdiv. RESULTS: The results showed that the information was received well by the parents (86.2% correct answers). The repeated test after 6 months showed worse results than those from the first test, with an increase of the wrong answers (1st test - 14 wrong and 36 incomplete answers; 2nd test - 29 wrong and 44 incomplete answers). CONCLUSIONS: The information in this form is received well by the parents but requires periodic repetition for the purpose of assimilating the newly-acquired knowledge.
