The regularity of dental care, preferably provided by one and the same dentist, exerts a positive effect on the incidence of caries and dental health knowledge. The DMF index and the results from interviews aiming at evaluating dental health knowledge were used in comparing groups of subjects without dental care and with regular or irregular dental care delivered by one and the same dentist or by different dentists.
