Caries data of 489 health vocational secondary schoolgirls between the age of 14-18 was recorded according to teeth, and toothsurfaces. The surfaces with caries and filling were expressed in percent, as the ratio of examined surfaces. The prevalence of extractions was also registered. The caries prevalence on occlusal and approximal surfaces of the individual teeth was analysed, and the similarity and increasing caries prevalence of the approximal surfaces in the upper second distribution of the approximal surfaces was analysed between the mesial and distal surfaces. The most important findings were: the high extraction of the first molars, the increase of occlusal caries rate in the second molars, the high and increasing caries prevalence of the approximal surfaces in the upper second premolars, and lower first molars respectively in the upper incisors.
